Necessary Matlab compiler options to integrate generated dll in VI

What Matlab compiler (mcc) options are required for Labview to be able to import the generated dll?
Using typical options, there are symbol definition problems with the header file.

I've never actually done this, but in searching the forums I found a number of helpful posts:

How to use matlab compiled DLL in Labview ?

I have LV 8.5, and am unable to use a matlab compiled DLL in my LV code. I have tried the 'import' command, but it does not list any functions. However, it does not show any errors during its execution. The existing solutions/responses to this question do not work either. I would also like to know of a way to deal with mxArray datatype. What is its equivalent in C (or any other high-level language) ? How do I retrieve an array that is returned from the matlab dll ?

I'm assuming you have either Matlab installed or at the very least the Matlab Runtime, otherwise the DLL won't work. The "import" command relies on having a header file. Do you have one? You also need to make sure the DLL has been compiled so that it's compatible with LabVIEW. The most likely problem is name mangling, which also occurs when you try to compile a DLL written in C++. See this post, which contains links to useful posts.
The mxArray datatype is a special datatype which is actually a structure. It's complicated. Your best bet is to create a C DLL that acts as an intermediary between the Matlab DLL and LabVIEW. If you are able to, you can, instead, simply call the Matlab code directly using the Matlab script node.

-keep-generated-actionscript Compiler Option Question

I'm trying to learn how Actionscript works. I turned on the -keep-generated-actionscript compiler option so that I could see the generated actionscript for an ItemRenderer I'm creating.
Should I:
1. directly edit the generated file, or
2. use the generated file as a reference for creation of my own ItemRenderer class file.
I'm thinking the latter, right?
all feedback appreciated!
many thanks,
Mark

You can do either, but there are AS item renderers in the SDK that are
better reference implementations.

BUG in Oracle SQL Developer 3.0.04 on the "generating DLL" with comments?

I'm newbie on oracle, but I think that I found out a bug in Oracle SQL Developer version 3.0.04 on the "generating DLL" tool using "comments".
I will describe the steps that I gave:
I created a view, but after I test it I had to change my “where” condition, so I comment the old code and then I wrote the new “where” condition below. After I done that I tried to look at the sql code of my view using “generating DLL” tool, but oracle sql developer only shown me half of the code, a lot of code were missing. Then I began with some test trying to understand what happen and I notice that if I put an invalid sql code in my comment the generating DLL start working with no problems, for example(pseudo-code):
(COMMENT WITH VALID SQL CODE the "Generating SQL" don't work:)
CREATE OR REPLACE VIEW <user>.<view_name> ( <column1>,<column2> )
AS
SELECT column1, column2
FROM table1
INNER JOIN
(SELECT
FROM table2
INNER JOIN .....
INNER JOIN ....
--where time_stamp = (select max(time_stamp) from .....)
WHERE time_stamp >= TRUNC(sysdate)
) t1 ON t1.ID = ....
AND ..... >= TRUNC(sysdate)
ORDER BY ....
Generating DLL returns this(when the error occurs):
CREATE OR REPLACE VIEW <user>.<view_name> ( <column1>,<column2> )
AS
(COMMENT WITH VALID SQL CODE the "Generating SQL" work with no problems:)
CREATE OR REPLACE VIEW <user>.<view_name> ( <column1>,<column2> )
AS
SELECT column1, column2
FROM table1
INNER JOIN
(SELECT
FROM table2
INNER JOIN .....
INNER JOIN ....
--where
WHERE time_stamp >= TRUNC(sysdate)
) t1 ON t1.ID = ....
AND ..... >= TRUNC(sysdate)
ORDER BY ....
I believe that "Generating DLL" tool have some problem with the comments, I also used /*...*/ to comment but the problem is still active.
I notice as well that if I started to add some more comments along the code, the conditions migth change, so I think the problem is related with "comments" code.
Would you mind telling me if this is a real bug or if I'm doing anything wrong.
Thank you in advance,
Rodrigo Campos

Hi Rodrigo,
Thank you for reporting this. The only bug I see currently logged on a comment affecting the generated View DDL involves ending the last line of the definition with a comment, which treats the ending semi-colon (even if on a different line) as part of the comment. That is actually related to a low-priority bug against an Oracle database API.
Unfortunately, your pseudo-code is a bit complex. Trying a few quick, simpler tests against the standard HR schema did not reproduce the issue. I tried INNER JOIN, and nested SELECTs. It would help greatly if you could provide a test case compilable against one of the standard schema, like HR or SCOTT.

Question about LabVIEW generated DLL's

Hello,
I want to try programming games in either JAVA or FLASH.
What I want to know is if I can use the LabVIEW generated DDL's for use in my games, without having to need the LabVIEW runtimes installed.
(in other words, are the LabVIEW generated DLL's, stand alone DLL's as generated in for example C/C++ or other programming languages?)
Second, how good is LabVIEW in converting it's code into a DLL. Can I make complicated algorithms, or are just simple functions allowed.
Hope you guys can spare a few words on this topic.
Sincerely,
Heinen

Hello dan_u and thank you for your quick reply.
If the LabVIEW Runtimes are needed to use the DLL's, that is not a good option for me then. I eventually want to distribute my games over the internet, and having to sent the LabVIEW runtimes with the games is just not an option.
To bad, I'm better in programming stuff in LabVIEW then in writen C++ like code.
Sincerely,
Heinen

Generating DLL with LabVIEW - A basic question

Hi everybody !
I'm trying to generate a simple DLL with LV. I have read as much as I could on the subject, prepared a small test vi (calculate x*x), built the corresponding dll, inserted and configured the ddl into another vi... Every thing seems to be fine, except that the ddl returns 0 whatever I'm doing.
I'm obviously missing something here, and I would be very gratefull if somebody could guide me out of this stupid corner.

Hi Chrisger & Becktho !
Thanks for your replies.
Unfortunately I'm still stuck.
First thing is that I followed already exactly the path develepped by Chrisger. I also tried changing the calling convention as suggestedc by Becktho. No success.
Second thing is that the ddl provided by Chrisger works perfectly (sorry Becktho, you just forgot the attachment...). At least that's something that shows I'm not entirely stupid, since I'm able to use a DDL compiled by someone else !
So, this seems to be a problem related to the way I am generating the DLL. Just in case, I have attached here the files I'm using (the source, the .bld file, and the generated DLL. Could you give them a look/trial ?

How to solve this problem..Pls advise...
Thanks
Sateesh

I suspect you are trying to compile the files one by one. You may also be trying to compile them disregarding the package structure.
From your post, I gather these files are in the package: com.geindustrial.sqms
Therefore, if they are not so already, put them under a directory structure:
com/geindustrial/sqms
and then compile with:
javac com/geindustrial/sqms/AddCtq.java com/geindustrial/sqms/Ctq.java com/geindustrial/sqms/VariableData.java
(The above is all on one line.)

Javac compiler options

Could anyone explain the difference between these two javac compile options:
-source <release> Provide source compatibility with specified release
-target <release> Generate class files for specific VM version
Say, I want to make sure my bytecode runs on Java 2 version 1.4 or above, which option should I choose?

Passing compile options in PKGBUILD honoured or overriden?

Hey there.
First post. New Arch user here, saying: hello! Been using Linux for years. Recently switched from a .DEB-based distro. Love the rolling release model and pacman and ABS (first time exposure to the latter - I don't even have it in my car!). Thanks for all the good stuff.
I figured a good way to start using Arch would be to contribute to the Wiki and to build a package or two.
In the PKGBUILD I submitted, I have:
make GCCOPTS="-DKERNEL2_1 -D_GNU_SOURCE -O3 -Wall" tleds || return 1
I included options like -O3 and -Wall verbatim from the Makefile of the original tarball. Do these get overridden by CFLAGS from /etc/makepkg.conf? (I pretty much left it untouched)
Is -D_GNU_SOURCE even necessary? (it seems to compile without it as well)
* Edit: changed subject.

In this particular case, the default Makefile needs to be modified or else the app won't work with kernels 2.1.x and up. This is taken care of by the $GCCOPTS variable (defined by the app author in the Makefile) which will pass the "-DKERNEL2_1" compile option to 'make'.
What I'm unsure of is: the Makefile also specifies "-O3" while /etc/makepkg.conf defines "-O2". Which one wins? Should the PKGBUILD not include that option and in that case would 'make' use "-O2" from the makepkg.conf?
Moreover, the Makefile includes "-Wall". Can/should this be omited? Does it really matter?
Asking questions is the only way to learn. Thanks guys!

TS1468 Where is the compilation option in version 11?

I have a single album what was split into 5 sections because of variations on artist name. Past support articles suggested using the Compilation option when selecting the multiple split portions. Where is that option in version 11 of iTunes? I do no see this feature.

Compilation can be found in the Get Info dialog. Generally all you need to do to link things is fill in an appropriate Album Artist. For more details see my article on Grouping Tracks Into Albums, in particular the topic One album, too many covers.

Adding Engine component causes: "Compiler errors occurred when generating a Windows Forms wrapper..."

I got this error when I tried to drop a TestStand Engine class onto my main form in VisualStudio.NET.
Compiler errors occurred when generating a Windows Forms wrapper for ActiveX control 'AxNationalInstruments.TestStand.Interop.API'
The error message went on to say that it saved the source in ./obj/AxInterop.TS.cs so I added that to the project. When I try to build it, I get this error:
The designer must create an instance of type 'System.Windows.Forms.AxHost' but it cannot because the type is declared as abstract.
I am using TestStand 3.0 evaluation, Version 7.1.3088 of Microsoft Development Environment 2003, and .NET Framework 1.1 Version 1.1.4322 SP1.
Is this aximp.exe problem?
Can someone suggest how to fix this?
Thanks,
Jeff

TestStand installs pre-built interop wrappers for the TestStand engine and all the TestStand UserInterface controls. You can find them in \API\DotNet\Assemblies\CurrentVersion\.
However, the best thing to do is usually to add the ApplicationMgr control to your .NET form and then call form.axApplicationMgr1.GetEngine() to get the engine. Doing this automatically adds references to the interop assemblies to your project. You can find this control in the TestStand tab of your .NET toolbox when you have a form active.
Ideally, you should start with the .NET simple operator interface examples which are in \OperatorInterfaces\NI\Simple\CSharp\ and \OperatorInterfaces\NI\Simple\VB.Net\

Passing extra compiler options to flexunit ANT task?

Hi,
Is there a way to send any extra compiler options to the <flexunit> ANT task?
I'm using conditional compilation and compilation (mxmlc) is failing from the <flexunit> task:
"Error: Access of undefined property DEBUG.
CONFIG::DEBUG {"
I tried sneaking "-define+=CONFIG::DEBUG,false" in with one of the other compiler options you can set on the <flexunit> task, but that just doesn't work or results in a validation error like this:
"One of the directories specified as a 'testSource' element does not exist."
Let me know if this is possible at all.

Not late at all! I think a response within a day on a forum is quite fast!

I'll also update the wiki @ http://docs.flexunit.org/index.php?title=Ant_Task to be more detailed regarding compilation so other don't have to dig.
Did you just do an update on that Wiki page or did I completely miss the part that explained the <flexunit> parameters?

In 4.2, which is super pre-alpha right now, I've added support to accept a series of flex-config.xml files provided by the user. Not sure if conditional compilation can be tackled with a custom flex-config.xml file, but if so then that'd be the feature that may help you.
Yes, being able to add (+=) a custom config file will solve this problem for me. You can define properties and values like this:
<flex-config>
    <compiler>
        <define>
            <name>CONFIG::DEBUG</name>
            <value>false</value>
        </define>
    </compiler>
<flex-config>
So in your AS code you can use:
CONFIG::DEBUG {
    // Do something that only should be done in debug mode.
I have another question, I ran into this one during testing my SWF with flexunit.
unittest.xml:82: java.util.concurrent.ExecutionException: command [<testcase classname='com.tuenti.video.unittest.testcase.player::MockPlayerCase' name='loadPlayer' time='0.000' status='success'/>] not understood
I had a look at the FlexUnitSocketThread.parseInboundMessages method that throws this error and it looks like that your defined END_OF_SUCCESS doesn't entirely match what the SWF is spitting out. They are of by 1 space: END_OF_SUCCESS is defined as: "status=\"success\" />", whereas my SWF spits out the following: "status='success'/>" (single quotes and no space before the closing of the tag).
It looks like I'm not the only one with the ExecutionException as it is reported on StackOverflow as well: http://stackoverflow.com/questions/3953677/flexunittasks-error-of-command-not-understood

How to specify java compiler options in JDeveloper ?

I am using JDeveloper 10.1.2. I downloaded and installed JDK 5.0.
In my "Project Properties"->"Libraries" I created a new "JDK 5.0" J2SE Version and pointed to the new JDK5.0 execuitable. So far so good.
Now I need to compile all my source code with -source=1.4 option. How do I specify java compiler option "-source=1.4" in JDeveloper ?
Thanks
Sachin

Even before compilig I am not sure that by just going to "Project Properties"->Libraries and creating a new J2SE, I now have the new compiler working with JDEveloper. How do I test this ?
