Call External shared library

Hi all
I have the following situation:
Oracle Version = 10g
O.S = HP UX 11
in the db I have define a library to run a C sl (shared library).
But when I try to execute my sl oracle return the following error:
ORA-06520: PL/SQL: Error loading external library
ORA-06522: '/home//EXE/exe_srv.sl' is not a valid load module: Bad object file type
ORA-06512: at "USER.SEMA_EXT_PROC_FUNCT", line 1
ORA-06512: at "USER.SEMA_EXT_PROC_TRI", line 4
ORA-04088: error during execution of trigger 'USER.EXT_PROC_TRI'
The configuration of the listner is the following:
SID_LIST_EXTERNAL_PROCEDURE_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = extproc)
(ORACLE_HOME = /oracle/product/10.2.0)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=/home//EXE/exe_srv.sl")
I did not understand the problem
Can you help me?
Thanks in advance
Fabio

It appears to be having no problem finding the library.
What is at issue appears to be that the library is invalid.

How to load external SWF used sharing library.

Hi~~~
Before ask the question, plz understand my bad English..
Recently I try to load the Swf file that is maded by Flash CS 6.0.
Especially it used shared library..
When I try to load this SWF, I used FileStream instead URLRequest.
This is because the target SWF File located same device with the Swf Application.. So when I use the URLRequest
it give me the warning - Sandbox security violation.
But by using FileStream, the warning did not occur.
This is the sample code below..
var myFile = new File(path);
var myStream = new FileStream();
myStream.open(myFile, FileMode.READ;
var myBytes:ByteArray = new ByteArray();
myStream.readBytes( myBytes );
mSwfLoader.loadBytes( fileStream, context );
mSwfLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoadedComplete);
As you can see, I made a event listener to get the content of the Loader, after receving Complete Event(I guess.. after decording?).
But I can't receive any event call, so I removed symbol used sharing library in the SWF.
And this gave me the result as I respected... So I guess the problem caused by using sharing Library..!
(In parenthease, I can see the valid result in running debug time on the Flash CS6..)
What should I do? I respect that using sharing libary give saving memory. So I want to using it as possible.
Thanks for your reading...!

Here is one way:

HTH,

When calling a function in a shared library, are parameters copied locally?

I have a shared library with a function whose header is:
void __cdecl nextevent(double Input[], int32_t len);
When called it sends the values in Input[] to the control Input:
This vi is compiled to a DLL which uses the header above.
My question now is: Which of these operations is the correct one:
1. The Input control is a reference to the array Input[], no values are copied.
2. The values in the array Input[] are copied to the control Input, the local copy is used by the vi, then the values in the local copy are removed/deallocated.
It seems reasonable to me that 1 is the correct one, but I can't be sure, and I can't think of any way to check it.

Solved!
Go to Solution.

For this particular case option 2 is valid. The reason is that LabVIEW arrays are not just pointers to a memory location but handles. And there is no legal way to create valid LabVIEW handles from an C runtime allocated memory pointer. So LabVIEW converts the incoming array pointer into a handle which is basically nothing else than allocating the handle with a size large enough to hold all array data, and then copies the data from the array pointer into this handle. After the call, the handle is properly deallocated.

Accessing an external HD as a shared library

Here's my situation: I have a personal collection of music (about 30 GB) on my MBP hard disk, which I manage with iTunes. As a part-time job, I am also a DJ. I recently ripped all of my 3500+ CDs onto an external dive, which takes up almost 200GB. What I would like to do is to access this as a shared itunes library - as if it were on another computer. I know how to use the external drive as my only itunes folder, but that's not what I'm asking. By using it as a shared library, I can have the music that I use with me at all times without connecting the large external, and only bring that along when I have a gig.
This will all be done under the latest version of Leopard, on the December 2008 model MBP. Thanks to anyone who can shed some light on this for me!

So are you saying that iTunes need to be running on a computer in order to share its library?
Yes.
If yes, then I obviously can't do what I want.
I can't tell really what you wan tat this opint.
As Meg pointed out in her first post, you can create 2 ibraries. One library on the external for DJing and one on the internal for you own use.
Does iTunes crawl all shared network directories for "iTunes Library.xml" files? I'm just trying to figure out how it searches for shared libraries!
No.
iTunes is running and you set it up in iTunes prefs -> Sharing to Share the library (or playlists).
iTunes on that computer will then broadcast that info on th elocal network.
If iTunes on another computer on that network is set up to look for Shared libraries, it will get that info and you can play songs from that Shared library.
Creating a new library is completely different.
Hold Option and launch iTunes.
Select *Create library* and select somewhere to put this new library.
It will be a complete, new iTunes folder. Any songs you add are added only to this library.
To use a different library (not a "shared" library), hold Hold Option and launch iTunes. Select *Choose library* and select the iTunes library file in the iTunes folder of the library you want.
This is what some people do when they want to keep a library for lossless and a library of AAC/MP3 for loading onto their iPod.

How to build a shared library (dll) of a VI to be called by VC++

hi All,
How should I build a shared library ( dll ) using LabVIEW so that the desired output from LabVIEW can be returned to the main program that runs in VC++ ?
I'm currently working in a project that uses the PXI 1042 & DMM, AWG, FGEN, SCOPE, RFSG, RFSA etc.
The VC++ programmers dont want the LabVIEW front-end to be visible when called into VC++, in the sense they don't want LV to be another front-end, as the entire software is designed using VC++. It is enough if I simply pass the final values of measurement to them for display purpose.
So, they've asked me if it is possible in LabVIEW to provide the VIs as dlls instead of exes.
Since I've seen the feasibility of building a EXE or a DLL in LV, I've replied positively to them.
In another of my project, I'm using dlls built in VC++ for hardware drive interaction parts in my LabVIEW project.
Likewise, what are the methodologies that I should follow when building a Dll in LV ?
I tried with a simple VI, wherein it returns a value of addtion of 2 elements & I passed it thro' the connector pane correctly.
When I called the same dll in LV itself & configured it correctly by specifying the correct return type & I/O, then also it did not run properly.
I could not understand what was going.
So experts pls help me out by some simple examples or related links.
Regards & Thanks,
Partha.

Sharing Library Stored on External Drive

I have an iTunes library stored on a firewire 800 drive attached to a new Mac Mini. The Mac Mini sees and plays all songs.
I can select the Mini as a shared library on another Mac and all of the metadata appears, but none of the songs play when clicked. After I've clicked on one song that doesn't play and then select another, I get an exclamation point next to the first track, but no exclamation points next to any tracks until I've tried to play them.
I've deleted all songs from my library and added them back, I've consolidated several times and I've tried holding option down while starting iTunes to select the library file located on the external disk. None of this has helped at all.
Both machines are running 10.5.6 and iTunes 8.1.
Any thoughts?
Thanks.
Brad

I'm having a similar problem.
I've set up two different user accounts on my iMac to separate my iTunes libraries, one ripped in AAC that I use for my iPod (stored on a partition on my internal HD) and one ripped in ALAC (stored on an external HD) that I use to wirelessly stream music to my main music system. Both are set up to share the library.
When I access them from my MacBook, both show some exclamation marks, but the are almost exclusively not the same songs. Go figure.
I have a SqueezeBox linked to my Lossless library, and it plays everything fine.
I've also installed Simplify Media (http://www.simplifymedia.com/) which restores the sharing iTunes over the internet feature that Apple dropped from iTunes a few versions ago. This too plays all the songs in my Lossless library just fine.
This seems to be iTunes sharing specific, and I'm glad to see that I'm not the only one to have this problem.

Linux Cannot Create Shared Library to call from Labview. Anyone have any ideas?

Hi there. A while back i created a shared library (.dll) to call in labview which works great. Lately i have been using Linux more and more and was hoping to recompile the shared library for use in Linux Labview. My first go I am getting the following error #error "Unknown Linux platform" from the platdefines.h. Evidently it does not like my system. Using QT creator on linux mint 64 bit. Anyone have any ideas on how i can get this working?
thanks so much!

I have a few version questions: What version of Windows was this DLL orignally created in? What version of LabVIEW are you using? What version of Linux are you using?
I think you will also find this previous discussion forum thread useful: http://forums.ni.com/t5/LabVIEW/Calling-DLL-on-LabVIEW-for-Linux/td-p/58322

TS2972 I can see the song titles in itunes shared library on my new imac but songs will not play. I have a pc with wifi network that the main music library is on. tried saving songs from pc to an external drive then to new mac but thats not working eithe

attempted to transfer itunes music from pc to new imac. didn't work. apple suggest using sharing method. main library of music is on pc. did those steps and shared library shows up on mac but when you click on the song to play it doesn't play or maybe ther is no content? any suggestions?

Hi there,
It sounds like your purchased content is not transfering via a flash drive. It may be easier to re-download this contnet directly from iTunes. Take a look at the article below for mor information.

Problem with JNI in a Solaris shared library

Hi,
I have a problem.
I have used JNI in my .dll on Windows & .so on Solaris . I have also used the same JNI code in a .exe on Windows & an executable on Solaris. 3 out of the above 4 combinations work & 1 doesen't. When I use JNI from a .so on Solaris 8(with/without the J2SE recommended patch), the JVM seems to have some exception & dumps core when I invoke CreateJavaVM(). See Below - I've included the output on the screen & the output from 'pstack core' :

This is an update to the original message -
I have tried both HotSpot & Server JVMs but still see the
same behavior. I'm using 1.4 .
I'd like to provide more information to those who can help
me. I have a feeling there might be something wrong in my
CC options. Thus you will find below what my CC statement
looks like for one of the files in my project & for the
linking of the final shared library. I also have
provided the output of ldd on my shared library libaicd.so
& for comparison the output of ldd on libjvm.so as that
might provide some usefull information just incase
something looks suspecious & might ring a bell.

How can I use a shared library made with the application builder?

Hi,
I am using LabVIEW 7.1 running on Slackware 10.1 (kernel 2.4.29) and I am trying to call a graph display from a C program that I use for debugging VME access from a VMIVME controler. So using the application builder I built the VI as a shared library (graph.vi -> graph.so) containing a function called "graph". In my main program the call to the dlopen fails with the error: "graph.so: undefined symbol: UninitLVClient". When I examin graph.so with nm I see that UninitLVClient and other LabVIEW functions are indeed undefined and using ldd shows that graph.so has dependencies only on libc.so.* and *linux*.so.* but not on LabVIEW related stuff. Those functions are defined in the liblv.so that's in the cintools directory but I have no idea if the user is supposed to use that.
So I think I am missing an important concept here. Can somebody help or direct me to some documentation (I found lots of information about how to link external code to LabVIEW but nothing about how to link LabVIEW code to an external program)?

Thanks Watermann,
your message has been very useful so now I am linking to the proper library but I still have problems when trying to load dynamically the shared library produced with LabVIEW. It is strange that I could successfully load the lvrt library at loading time but it does not work when I am loading the library at execution time.
I made a small LabVIEW program that prints a hello window and I am calling it from a C program. In the first program main.c I am linking to the lvrt library at loading time and it works but in the second one I am linking dynamically at execution time and it does not work. For my work I need to be able to load code done in LabVIEW at execution time. Any help is appreciated!
Program main.c:
// small program to call a LabVIEW shared library
#include
#include
#include "hello.h" // got this from the LabVIEW builder, i.e. when I made the hello.so
int main(void)
printf("Hello from C!\nLets call LabVIEW now\n");
hello();
printf("Bye ... \n");
return 0;
The command to compile main.c, i.e. linking shared library lvrt when loading main program:
gcc -Wall -I /usr/local/lv71/cintools/ -o main main.c hello.so -l lvrt
The LD_LIBRARY_PATH has been defined and exported:
$ LD_LIBRARY_PATH=$PWD
$ export LD_LIBRARY_PATH
IT WORKS!
Program main2.c:
// small program to call a LabVIEW shared library
#include
#include
#include
int main(void)
void * h_lvrt;
void * h_hello;
void (* hello)(void);
char * error;
printf("Hello from C!\nLets call LabVIEW now\n");
// open LabVIEW RunTime shared library
// in my computer located at /usr/local/lib/liblvrt.so
h_lvrt = dlopen("/usr/local/lib/liblvrt.so", RTLD_NOW);
// check for error
error = dlerror();
if (error) {
printf("error : could not open LabVIEW RunTime library\n");
printf("%s\n", error);
return 1;
// open hello shared library
// in my computer located at /home/darss/lv_call/hello.so
h_hello = dlopen("hello.so", RTLD_NOW);
// check for error
error = dlerror();
if (error) {
// close LabVIEW RunTime shared library
dlclose(h_lvrt);
printf("error : could not open hello library\n");
printf("%s\n", error);
return 1;
// get function hello from library hello.so
hello = dlsym(h_hello, "hello");
// check for error
error = dlerror();
if (error) {
// close hello shared library
dlclose(h_hello);
// close LabVIEW RunTime shared library
dlclose(h_lvrt);
printf("error : could not get the hello function\n");
printf("%s\n", error);
return 1;
// call hello function
hello();
// close hello shared library
dlclose(h_hello);
// close LabVIEW RunTime shared library
dlclose(h_lvrt);
printf("Bye ... \n");
return 0;
The command to compile main2.c, i.e. dynamically linking library lvrt at execution of main2 program:
gcc -Wall -o main2 main2.c -l dl
The LD_LIBRARY_PATH still defined and exported.
IT DOES NOT WORK!
Program output:
Hello from C!
Lets call LabVIEW now
error : could not open hello library
/home/darss/lv_call/hello.so: undefined symbol: WaitLVDLLReady

How to make the symbol to be resolved within the shared library ?

I have two definitions of a symbol, one is in the main code, the other in a shared library. I want the symbol to be resolved within the shared library if it needed in the shared library.
From the 'C++ User�s Guide', use the option '-Bsymbolic' to build the shared library is a choice. But it also said 'Never use -Bsymbolic with programs containing C++ code, use linker map files instead. So I have to try to use the map file, but I did not get more useful information from 'Linker and Libraries Guide'.
I want to know what should be included in the map file and how to generate the map file?
Additionally, from the 'Linker and Libraries Guide', the 'Direct Binding' also could resolve this problem. And I tried to build the shared library by the '-B direct' option, it works.
Could anybody tell me what's the difference between the '-Bsymbolic' and '-B direct'?
Any comments are appreciated.

You didn't provide fun.h, and you didn't show all the commands that you must have used -- there are no commands that compile the source code into .o files. So I can't tell why the -xldscope option didn't work for you.
Problems and errors that I see in your example:
Functions func and swap are referenced from C code, but swap and one of the func functions are compiled by the C++ compiler and will get mangled names. If you compile a function with the C++ compiler that is to be called from C code, you need to declare the function as extern "C". But the extern "C" in a shared header needs to be guarded by +#ifdef __cplusplus+, since a C compiler won't understand the declaration.
When you build a shared library, you must explicitly list the libraries it depends on, since no dependencies are created by default. For a C++ library, you need at least -lCrun -lc in that order. Otherwise, in a real-world program you can have program failures due to incorrect library initialization order. To be sure you have listed all needed libraries, use the -zdefs option, which causes the linker to complain about missing definitions.
To be sure the shared library is picked up at run time, provide a RUNPATH via the -R option when you build the executable.
The -xldscope option must appear on compile commands for the files where you want it to take effect. It has no effect on a link command, because the option affects how code is generated.
Here is my rewrite:
% cat fun.h
#ifdef __cplusplus
extern "C"
#endif
void func();
#ifdef __cplusplus
extern "C"
#endif
void swap();
% cat fun.c
#include <stdio.h>
#include "fun.h"
extern "C" void func()
    printf("func in the shared lib\n");
extern "C" void swap()
    func();
% cat fun_in.c
#include <stdio.h>
#include "fun.h"
void func()
    printf("func in the main code\n");
% cat main.c
#include <stdio.h>
#include "fun.h"
int main()
    func();
    printf("invoke the swap:\n");
    swap();
% CC -G -xldscope=symbolic fun.c -Kpic -o liboutside.so -lCrun -lc -zdefs
% cc -o run main.c fun_in.c -L. -loutside -R .
% ./run
func in the main code
invoke the swap:
func in the shared libAs you can see, it works as advertised.
Please note that the -xldscope option affects all functions in the module. If you need more fine-grained control, you must add declarations to the source code, or use a mapfile instead of -xldscope .

How to create a c++ shared library (.so) for linux real time (for myRio) with Eclipse to use in LabView?

I tried already these Tutorials and Advices but I didn't find a solution:

- http://www.ni.com/tutorial/14690/en/
- http://forums.ni.com/t5/LabVIEW/Shared-Library-on-myrio-Linux-Real-time-system/m-p/2842540/
- http://forums.ni.com/t5/LabVIEW/How-to-create-shared-library-for-linux-real-time-target-in/m-p/28218...
- and some more
I want use c++ codes on linux real time. For testing reasons I want to have a function that adds 2 values and gives the result.
I've done these steps:
1. writing a c++ file in Eclipse (see screensot 2)
2. building a shared library (.so) from my c++ project in Eclipse (with Cross GCC)
3. putting this file on myRio (path: /usr/local/lib/)
4. creating a VI that calls this library from Labview with a "Call Library Function Node" (see screenshot3)
5. Setting the properties for the "Call Library Function Node" (see screenshots 4-7)
After I run this VI i get this error message: LabVIEW: (Hex 0x627) The function name for the ... node cannot be found in the library. To correct this error, right-click the Call Library Function Node and select Configure from the shortcut menu. Then choose the correct function name. (see screenshot1)
I've tried a lot things to solve this problem but I couldn't find a solution. Would be very happy if anyone can help me. I guess that I have to edit my c++ code to export my function (symbol). But I have no idea how to make it. I also tried it with a dll file in the same folder but it didn't help.
Perhaps someone can send an example which works on myRIO.
Thanks!

can see it in the screenshot8 there is a function called "_Z8AddierenddPd" instead of "Addieren". I copied this name to Labview (see screenshot9) and it worked.
I'm sure that there is a way to compile the shared folder with gcc without decorations (mangling). But I don't know how. If someone has a recommendation I would be very glad!
Prepend each function declaration that you want to be available without name decoration with
extern "C" <your function declaration>
Or if you have multiple functions you want to export you can in the header file where you declare your functions simply use:
#ifdef __cplusplus
extern "C" {
#endif
<all your function declarations>
#ifdef __cplusplus
#endif

How to call external Perl routines from Pl/SQL - Urgent

Available software in the Test Environment:
1. Sun Unix 2.8
2. Oracle 8.1.7 ( 8i)
3. Perl 5
Iam trying to call/execute perl scripts from PL/SQL using the DEMO_RDBMS.mk. I am able to call C scripts from PL/SQL, but actually want to call Perl scripts.
The steps followed for for C are -
1. Create and compile a simple C program to execute a unix command (eg., touch a file).
2. Make a shared library of the above compiled program (object), i.e., load the compiled object module into a dynamic load library.
3. Declare the above library in Oracle using SQL*Plus.
4. Define a PL/SQL function or procedure to call the external routine.
5. Test the external routine.
The above steps run good for a C program, but step 2 fails when run for a Perl script.
When I tried to use the following command for step 2 -
make -f $ORACLE_HOME/rdbms/demo/demo_rdbms.mk extproc_callback \
SHARED_LIBNAME=cmd_lib.so \
OBJS=tst_cmd.pl
got the following error -
ld: fatal: file tst_cmd.pl: unknown file type.
ld: fatal: File processing errors. No output written t cmd_lib.so
*** Error code 1
This gives me an indication that demo_rdbms.mk does not understand/interpret Perl scripts. Going through the demo_rdbms.mk suggests the same.
My questions is - How do we call external Perl scripts/routines from PL/SQL ??
Do I have to get a different version of "demo_rdbms.mk" ?
PS: The perl scripts used above (tst_cmd.pl) is error free and works as intended in the unix environment.

Iam trying to call/execute perl scripts from PL/SQL using the DEMO_RDBMS.mk. I am able to call C scripts from PL/SQL, but actually want to call Perl scripts. Well, C is a "compiler" language and Perl is interpreted. In a sense, C is not "scripts".
When I tried to use the following command for step 2 -
make -f $ORACLE_HOME/rdbms/demo/demo_rdbms.mk extproc_callback \
SHARED_LIBNAME=cmd_lib.so \
OBJS=tst_cmd.pl
got the following error -
ld: fatal: file tst_cmd.pl: unknown file type.
ld: fatal: File processing errors. No output written t cmd_lib.soI guess this compiles an extproc "stub" with your object file, generating an external procedure. So the object file really needs to be an object file :-)
My questions is - How do we call external Perl scripts/routines from PL/SQL ??I'd guess you need an embedded Perl interpreter in the external procedure.
Not much help though I'm afraid :-/

Calling external C procedures from PL/SQL

Hello,
The first two development steps for external C procedures are:
1. Create and compile the external procedure in 3GL.
2. Link the external procedure with the standard shared library at the operating system level.
For others, for example for 3. Create an alias library schema object to map to the operating system's shared library, i can see details of how to do this, but for first two, i see "Varies for each operating system; consult documentation".
My question is, how can 1 and 2 be done, in case of Windows? So i have the .c file, where i've written a procedure. And next what should i do for the first two steps?
Thanks

The "standard shared library at the operating system level", is that .dll file, isn't it?Yep. On Linux/Unix these are actually called shared libraries.

Transferring external iTune library from one computer to another

I am having great difficulty in changing my external iTunes library from my old MBP laptop to my new iMac 5k.
My entire iTunes library is stored on an external drive and can be accessed directly with my MBP. When I started up iTunes on my new iMac, it created a new empty library in the MUSIC folder. What I want to do is connect my new iMac to the external library directly. I can see it when I turn on HOME SHARING but only when iTunes is running on my MBP, which is useless since my MBP will now be seldom used. I have of course on the iMac, changed the library location in the advanced preferences to the external location, to no avail. I do not want to keep any media files on the iMac for capacity reasons.
To compound the problem, I cannot seem to sync my new iPhone 6+ to the original external library, only the new empty one!
Surely this ought to be a simple job, transferring an external iTunes library from one computer to another! Am I missing something obvious here?

Wow, what a quick response! Thanks, Limnos. I guess it was bleeding' obvious, and I should have thought of it before. Such a simple solution!
On a related matter, I also have just realised that the iTunes iOS backups are saved on the internal computer drive in a folder called MOBILESYNC rather than on an external drive, thus chewing up a lot of capacity on my SSD. Others reading this response may be interested to know that it is easy to have iTunes save the iOS backups to any external drive using a symbolic link in this directory. Go to
http://support.digidna.net/hc/en-us/articles/203504123-Storing-your-iPhone-Backu ps-on-an-Alternate-Location
for the details.
However, note that iBooks will NOT let you use this work-around, pathetic app that it is.
