TTClasses C++ Shared Objs Names And gcc Compiler Versions
3 versions of the TTClasses libraries are shipped with TimesTen due to the fact that gcc 3.2, 3.4. and 4.1 produce binaries that are not compatible with each other. For instance with 7.0.2 has the following libraries:
libttclasses.so.gcc323
libttclasses.so.gcc346
libttclasses.so.gcc410
It appears the naming convention of these libraries indicates the gcc compiler version out to 3 digits that TimesTen used to create the libraries.
As new releases of TimesTen occur, when will the names of these 3 libraries change, i.e. when will TimesTen use a different version of the gcc compiler?
It appears that in 7.0.2, 7.0.2.2, and 7.0.3, the names of libraries don't change. Would it only be possible for them to change for a major release, i.e. 7.X. Could it change for a minor release like 7.0.3.X or 7.0.X?
The reason that I'm asking this is as follows:
- When the TimesTen installer is run, it checks version of the gcc compiler, then it creates a symbolic link to the appropriate lib for that version of the compiler. It names this link libttclasses.so.
- Up to now we have been linking our programs with libttclasses.so.
- However when TimesTen is run on a machine without a compiler (which is the situation in our QA and prod environment), it appears to create a link to the gcc 3.2 lib.
- This is a problem for us on Red Hat 4.0 because the default compiler is 3.4 which is what we are using, but the installer is creating a link to libttclasses.gcc323 when there is no compiler on Red Hat 4.0.
- This causes our programs to crash.
- To eliminate this we are considering linking directly with the appropriate library, i.e. libttclasses.gcc346 in our case.
- However, we dont want to have to recompile or relink or application for future minor releases of TimesTen, i.e. 7.0.3.X or 7.0.X.
- If the names of these files could change in minor releases, then we'd need to relink.
Does anyone know the answer to this?
Thanks.
As you say, the names of the libraries comes directly from the GCC version used to build them. These names (i.e. GCC vesions) will not change between minor releases. Over time and major releases will tend to drop support for older GCC versions and add support for newer versions.
Our strong recommendation is that you change the symbolic link to make libttclasses.sp point to the correct library and then link with libttclasses.so. This is the simplest and most 'future proof' method.

Which Compiler version to Upgrade to....
Hi All,
Currently we have following compiler verion on Solaris 8
CC: Sun WorkShop 6 update 1 C++ 5.2 Patch 109508-09 2002/07/08
We are planning to move to Solaris 9 and above compiler version is not supported on Solaris 9. In the process we also want to upgrade our compiler.
I looked in to Sun Site, Sun Studio 11 is available for free.
http://www.sun.com/software/products/studio/index.xml
But it has been released like a month back. Currently, we are hesitent to take any risks with this compiler...
Can anyone suggest which is the version we should be upgrading to ?
- Thanks in Advance
NagendraHi
If you wish to be very conservative, you could switch to Forte Developer 6 update 2. This supports Solaris 9. However, this stopped shipping about 2 months ago, so it is perhaps not the best choice. Your 6u1 licence(s) should also work with 6u2.
The 2nd most conservative option is to go with Studio 10. This has been out since January.

Can i use a GCC compiler on MacOSX and link this C Code to lbv 6.1 on OS9?
I am interested in compiling my C code on the free GCC compiler which works with Mac OS X but am concerned that I will not be able to connect this with the Call library function and CINs in labview 6.1 that runs on Mac OS 9. Am I able to cross platforms and use the .so file with lbv 6.1 on OS 9? What problems will i most likely encounter or should watch out for? Thanks!
Unfortunately, you cannot port shared objects across these platforms. You are going to have to recompile the .so file on OS 9 for use in the call library function node.

Is it possible to change the font name and size without having to compile?
Dear All
We have one requirement that we need to change the font name and font size at run time dynamically without having to compile all the forms in 6i.
Is there any way or work around to achieve the same.Kindly suggest us.
something like using uifont.ali or forms60_defaultfont, or set_item_property
Thanks and Regards
Thangaraj.Dear All,
Thanks for your updates, Technically what both of you said is correct. but in application server we used something like ClientDPI to match the client server font with the application server, i need to know that is there anyother way something like this...?
I have read one document(Note:28397.1 in metalink) saying that using uifont.ali file we can change the font at run time, but i have used this only for report
Thanks and Regards

How can I use the "gcc compiler and emacs editor" in Solaris 8 for Intel?
I installed Solaris 8 for Intel to my desktop computer.
After the installation, I found I couldn't use the companion software (the software CD included in the Multilinugal Media Kit for Solaris 8) - especially the emacs editor and gcc compilers.
I certainly installed the companion software to my computer. And I can identify that those softwares are
really installed to my system. In order to check out whether I installed them or not, I went to the "System Administrator" and opened the "Solaris Product Registry", in which I identified that all the files in
the companion software were succesfully installed in my computer.
However, when I open terminal or console box and tries to use those
software, the system responds that "there is no emacs or gcc."
Why I cannot use those things?
Did I install the companion software wrong?
I really don't understand why I can't use them.
For your reference, I saw the directories "/usr/bin" and "usr/ccs/bin"
too.
In /usr/bin I typed
#as
and no such command.
In /usr/ccs/bin
#as
and also no such command
was what I had as a response.
If I installed the companion software CD correctly and if they are installed somewhere in my computer,
where I can find them and how I can use those softwares?
Lastly, whenever I try to connect to my ISP via telnet mode, I see this
message.
"Try to connect ...
connected to ***.***.***.*** (IP address of my ISP)
Closed by foreign hosts."
Is there any one who knows why this happens?
Thanks for reading my question.gcc and emacs install in /opt/sfw. You should change your path statement to include /opt/sfw/bin and should obtain the FAQ from sunfreeware.com. The FAQ answers all your questions.
I have installed gcc and gtk and am using both at this time.

File name and Date Display as an obj not the data
All,
The issue that I am having is that when I view a Visio file hosted on SharePoint. The file was created in Visio 2007 and when it is opened by Visio 2007 and Visio Viewer in SharePoint. The file name field object and date
modified object show the information. The issue is when the file is opened by a device that has Visio 2010 the information does not show. Is there something that I can do for these users to have it show correctly.Hi，
Which way did you open the Visio 2007 file in SharePoint？Opened it in the browser or downloaded it to open？ I had test in my environment. Insert a text box>Add a data/time field, it worked fine both in Visio 2007, 2010.
Thus, let‘s do some test to narrow down the issue’s reason.
1.Download the Visio 2007 file and open it with Visio 2010.
If it worked fine, the issue seems more related to Visio object and sharePoint connection.
If it does not display the information in Visio 2010 by a device client, the issue was more related to Visio 2010 client.
2.Create a new drawing included file name and Date
field in Visio 2010.
If the new drawing displays correct, the issue is more related the original, please try to repair the file or re-create the file name and Date filed.
If the new drawing still displays incorrect, please try to start Visio 2010 in safemode, some third-party add-ins my be casued the issue.
If the issue still exists, try to repair Visio 2010.

George Zhao

Creating JNI DLL on WinXP using MinGW and GCC
Ohh man, I spent entire day fighting with "UnsatisfiedLinkError "while trying to cal my native method. After reading all the posts with similar problems, and checking for every little thing that was suggested I figured it out. So I'm reposting the solution here since no one else had suggested this.
The solution to my problem was that g++/gcc compiler needed an option "-Wl,--add-stdcall-alias". This was the killer. I had the "-shared", but it wouldn't link without the "-Wl,--add-stdcall-alias" option!!!
As a summary, while its fresh in my mind, here are the trouble shooting steps I used:
1) Check package names and the generated .h file using javah. I checked and rechecked the names, even created simpler static void method to try and get it to link.
2) Make sure to use the "jobject" parameter for dynamic methods and "jclass" for static methods in the signature as second argument.
3) That method name starts with "Java_" and I stress the CAPITAL "J", can not be lowercase. Although if you are using javah, that should not be the problem, since javah can not ommit this kind of detail. The only thing that you need to check for is that if you change method from dynamic to static, and don't rerun the javah, or javah doesn't replace the previous file. So make sure you restart clean and that javah regenerated the file with "jclass" or "jobject" whichever is the case.
4) Used the "java -verbose:jni" debug flag to see my native method loaded. In my case when it wasn't working I couldn't see the method load, but there were no error messages from "System.loadLibrary" or from the verbose output. Only the UnsatisfiedLinkError. Frustrating. After the fix it loads perfectly:
[Dynamic-linking native method org.jnetpcap.Pcap.openVoid ... JNI]5) I used "nm" found at "c:/MinGW/bin/nm.exe" to dump the symbol table, and I could see all my methods, with the appropriate named marked as text (T) flag. They were not being loaded when viewed using "java -verbose:jni" though.
6) I put "extern "C" {}" around all my JNI C++ methods.
7) Tried a gazilion other gcc options, posted in various messages, none worked.
8) Finally came accross the "-Wl,--add-stdcall-alias" flag which fixed it.
Here is a portion of my Makefile for reference:
$(LINK_TARGET) : $(OBJS)
g++ \
-shared \
-Wl,--add-stdcall-alias \
-o $@ $^ \
$(LIBDIRS) $(LIBS)LIBDIR and LIBS point to a single external library dependency.
My IDE environment is Eclipse 3.2, but I run everything from Makefiles as external programs.
I wish this was documented somewhere, would have saved me an entire day of troubleshooting.
Cheers,
mark...

voytechs - added CODE tagsGlad my post helped out at least a few people.
Believe it or not, I'm in the same boat now on Linux.
Atleast I know its the name mangling problem again. I
see a few symbols unmangled with nm, but most are,
and those are then one's JNI is complaining about
with UnsatisfiedLinkError.
So now I'm going through various post related to
linux and trying to find the same type of flag. The
"alias" flag doesn't work with RH4 g++ version
4.0.2.You should not need a flag on Linux. A typical compile for me on my Linux box is:
gcc -shared -o libjnitest.so -I/usr/java/jdk1.6.0_01/include -I/usr/java/jdk1.6.0_01/include/linux jnitest.c>
Window builds perfectly fine, but now I'm creating a
new platform target. Everything compiles and creates
the shared library, just can't get JNI to be happy.
BTW, my project: http://jnetpcap.sf.net
Ah. You have .cpp extensions on your filenames. Are you using gcc or g++ to compile? If you don't use g++, you can get errors such as:
undefined symbol: __gxx_personality_v0

I am trying to run a script as a patch to the install Oracle 9i on UL. First it fails with libjava.so not found. Then I tried to apply patch 3423540 as suggested by Oracle. Here is the actual script that should run. Needs the gcc compiler - so installed that from ul distribution. And now while running the patch it cant find standard include directories like errno.h and syscall.h . Any help will be appreciated
#!/bin/bash

if [ $USER != root ]; then
echo "Must be root to run this script, please login as root and re-try"
exit

# see if libcwait.so is already being loaded
if [ -f "/etc/ld.so.preload" ] && [ -n "`grep libcwait /etc/ld.so.preload`" ]; then
echo "Patch has already been applied"

fierrno.h and syscall.h are provided by glibc-headers package. So check whether this package is installed on your system.
I'm not sure what UL means?
dou you mean United Linux or Unbreakable Linux (aka Enteprise Linux)?
If you mean Unbreakable Linux then you can check this installation paper: http://ivan.kartik.sk/oracle/install_ora9_elinux.html -
Difference between VS2013 and GCC debug symbols
Hi guys,
I am writing you today as I am having trouble with my software. it has a Windows and a Linux version, each of them respectively using a static library (C++).
I notice that, if I build my Windows static library as RELEASE without any debug info : /O2, and Debug Information Format -> None and manually removed.pdb, the .lib file size about 40mb.
On the contrary, regarding the Linux library, I use GCC in order to build it as RELEASE as well: -O2 and -g0.
Once compiled, my .a file's size is about 12mb.
Well, those compilers are completely different, and the library's size doesn't really matter.
Of course, my application, which needs the library, has debug symbols generated (whether I am on Windows or Linux).
While debugging, I can have access to all of the members/classes of my application (and also the ones from my Windows library), using Microsoft Visual Studio 2013.
And now, while debugging with the Linux lib (within Eclipse), I have access to my class members, except the one from the library.
I was wondering what's happening in the background:
_ Why does it seem like the Windows version of my library contains more symbols/data, which allows me to debug my program using the library ?
_ Why can't I debug the objects from my Linux library ? (this one is about four times smaller than the Window's one)
If I try to access to some classes from my library, Eclipse/GDB says <incomplete type> in the Debug view.
I am lost on this point. Does anyone know about that ?
Thank you very much for your help !Hi ddocteur,
Appreciate your patience and sharing detailed information.
It does need to cost some time to to involve someone familiar with this topic to further look at this issue. Your detailed information will be quite helpful, and there might be some time delay.
Thanks for your sharing and understanding.
Best Regards,
Carl

Object is to sync address and calendar between laptop with Max OS 10.4.11 and iPhone. Upgrade of our 10.4.11 laptop to 10.5 is accomplished and we now need to upgrade Quicktime and iTunes; however, the user name and password for the laptop is now not working after the upgrade to 10.5., though it was working prior to the upgrade, for file sharing.
@ BDAqua > I tried your suggestion but no luck. holding opt+command just gave me a blue screen and it rebotted, pushing the disk out of the drive. Yes, the macbook has 1 gb of ram. I realize that the min req. call for 2 gb of ram so i've got an order in for another dimm to put into the machine. Thanks for your suggestions.
@ a_brody > Yes. The machine was plugged into a power source. The disk promts you to do that and i recall aspect this form other installs. Thanks for the reminder tho! ( btw your second post is like greek to me man!)
@ Kuncklesmac > You're right about Snow Leopard being an upgrade from Leopard. I'm aware of this. And yes previously i've been told by Apple that I needed the Box Set (not the family pack. i am using the family pack for OS Snow Leopard) to upgrade my 10.4.11 mac - they never mentioned adding ram but i figured that out on my own and an apple specialist recommended it when i purchased Snow Leopard and confirmed that I coul duse the Snow Leopard to upgarde from Tiger (10.4.11). I've also read extensively (as i said above) that it isn't necessary (always) to buy the box set. Several 10.4.11 users report having upgraded using the Snow Leopard upgrade disk only (not the Box Set) without trouble on intel macs (also see the apple link i posted). So i'm just ondering how they did it and i cannot.

There was one time where my wi-fi wasn't connecting so I tried to turn it back on. A window popped up but I had alrdy clicked enter before I read it, but it said something like "...will change settings, is that okay...?" And then wi-fi still would not connect. So I tried restarting my computer, but when it turned on, my user account did not show up and all there was on the screen was two boxes that asked for name and password. I was the only person using my macbook so I never set up a password for it. Has anyone had this problem? How do I fix this?
Since I'm not in front of your computer I can't tell what you see - I can only guess and give a hint. So once again, if the disk name on your Mac is "Macintosh HD", when you boot in Recovery Mode, and start up the Terminal in "Utilities" menu, and then type in the command:
df -k
you should see a list of "volumes" - one of which is named "/Volumes/Macintosh HD" (but yours could be anything) and in that folder there is another folder called "Users" and in that folder is the names of the home directories of the user accounts (and the names that you can enter into the login screen) that you are looking for. So if you are not familiar with using the Terminal you should say so and I can give more details. But assuming you're OK with typing in commands to theTerminal this is what I would try:
ls -l /Volumes/Macintosh HD/Users
and you should see something like the following (my disk name is "Yosemite" so I typed "ls -l /Volumes/Yosemite/Users")
ML9Book:~ xxxx$ ls -l /Volumes/Yosemite/Users
total 0
drwxr-xr-x+ 11 Guest _guest 374 Oct 25 19:23 Guest
drwxr-xr-x+ 33 Jack staff 1122 Oct 24 10:49 Jack
drwxrwxrwt 13 root wheel 442 Dec 27 2013 Shared
drwxr-xr-x+ 38 admin staff 1292 Oct 25 16:59 admin
drwxr-xr-x+ 15 x13 staff 510 Oct 23 22:41 x13
drwxr-xr-x+ 12 514 staff 408 Oct 23 12:24 x14
So now reboot your mac into normal mode - and you will see the login screen with the two empty boxes.
So the above output tells me that there are 3 users - Jack, x13 and x14 (there is always a Shared user and there might or might not be a Guest user since it depends on how your setup was setup) - and these 3 are the names that I could try and enter into the login screen (in the top or first box). You can try no password, but I don't think you can create accounts without passwords, so this will likely fail. In that case you need to reboot in recovery mode and run the Terminal command again (from the Utilities menu) and do a resetpassword command. Another window will pop up and from there you select the Volume (in my case I selected the Yosemite volume - in your case you would select the "Macintosh HD" if that is what your volume name is). Then select the user account you want to reset the password from the drop-down list of user accounts (it will show you the long and short names, and the short name is what was in the listing above from the "ls -l" command), then enter the new password in the indicated box, and then enter it again in the next box, to make sure you didn't make a typo, and enter a password hint in the last box (optional). Then click the "Save" button and you will see another dialog box pop up telling you that the password was changed but not the Keychain password (hopefully you remember this one) - click the OK button then reboot back in normal mode (click on the Apple logo in the top left corner of the screen and click on Restart).

Class name and package name clashing
When i have a class and a package with the same name, I cannot access classes in the package. For example I have 3 classes and 1 package as below
- Test.java
- PackageName.java
+ PackageName // this is a directory
- MyClass.java
Below are the codes of .java files
Test.java
=======
public class Test { PackageName.MyClass a = new PackageName.MyClass ();}
PackageName.java
===============
public class PackageName{ }
MyClass.java
==========
package PackageName; public class MyClass { }
I can compile PackageName.java and MyClass.java but not Test.java. It says
cannot resolve symbol
symbol : class MyClass
location: class PackageName
PackageName.MyClass a = new PackageName.MyClass ();
But if I remove the PackageName.java, I can compile Test.java perfectly. I think when I use PackageName.MyClass, java thinks that I try to access an inner class MyClass of PackageName class, and that does not exists. Is there any way to solve this ambiguation, other than making the package name and class name different? Thank you very much.This works fine: just add an import to Test.java.
import PackageName.MyClass;
public class Test
public static void main(String [] args)
MyClass a = new MyClass();
public class PackageName {}
package PackageName;
public class MyClass {}It's a pretty wacky, useless example, but it works.
Plus I thought inner classes would have a dollar sign in their .class file names. When I compile this:
public class OuterClass
public static void main(String [] args)
OuterClass outer = new OuterClass();
System.out.println(outer);
public String toString() { return "I'm an OuterClass"; }
class InnerClass
public String toString() { return "I'm an InnerClass"; }
}I see two .class files: OuterClass.class and OuterClass$InnerClass.class
Why make up examples like this? It's hard enough writing code, and it's easy to disambiguate for the compiler. -
Time Capsule won't accept my user name and password for access - Help!
Hi all,
My Time Capsule seemed to stop working one day and I had to do a hard reset with the little button at the back. After that it worked and I restored my wireless network settings but now I can't access the Time Capsules hard drive with Time Machine.
When I try to choose it as my Backup Disk in the Time Machine preferences it says "Enter your user name and password so Time Machine can access the file server "Our Time Capsule" (the name of my time capsule). However, every time I try to enter my password I get "Sorry, you entered an invalid username or password".
I've already tried several resets of the Time Capsule and I've also tried logging on my computer as the Root user and changing my administrator account password back and forth but no go.
Help! and Thanks.Norman & Harry,
Consider the following:
*_Time Capsule Keeps Asking Me For a Password_*
It will be important to know what is going on, or what you are doing when it asks for the password. Is it asking for a password only when Time Machine attempts a backup? Consider this:
It is NOT your username and password it wants when you try accessing the Time Capsule. (I know... it SAYS "username and password") But it means the Time Capsule's Name and Password.
You will find that by launching Airport Utility.
Select the TC on the left.
Click "Manual Setup".
Click the "Time Capsule" Tab.
You will see "Time Capsule Name:" and "Time Capsule Password".
Make sure “Remember password in keychain" is checked.
That is the information you need to enter when it asks for "username & password."
*I Don’t Remember What My Time Capsule Password Is*
You can see what your current TC password is by going into Keychain.
Open your Keychain and select "login" from the Keychains pane in the top left. Highlight "Passwords" in the Category pane from the lower left.
Sort all the items by Kind. Note everything labeled "Airport...". How many do you have listed? There should only be one "Airport base station password" for each base station that you have active. Also, there should only be one "Airport network password" for each network you have created. If there are more than these, then delete all but the ones with the most recent Modification date.
To see what passwords are being stored, double-click your Time Capsules' entry. A new window will appear.
Put a check beside "Show Password". You may be asked for your own Admin password so enter that.
Now the Password field will display the password you entered into Airport Utility for your Time Capsule
*It Still Won’t Accept the TC Name and Password*
Launch Airport Utility --> Manual Setup.
Select "Disks" in the tool bar above.
Click the "File Sharing" tab.
Is "File Sharing" checked? It should be.
What is selected beside "Secure Shared Disks"? If it says "With Accounts" or "With a Disk Password" then the system will ask you for a password every time it mounts the TC hard disk. If you switch it to "With Time Capsule Password" then use the password you designated earlier in the “Time Capsule" tab. It should only ask you once and then never again - because you had checked "Remember password in keychain".
If you have made any changes then click "Update".
Let us know if this resolves your issue.
Cheers!
