Troubleshooting compiled code?

I am using Fieldpont modules to control some lab tests. Since we have a few separate tests, we've decided to use compiled code to cut down on Labview costs.
The issue I'm having is when I have an error in the compiled code on a new install. Is there any way to see where in the code the error is occurring? Maybe some sort of test run mode or something? I know the code interacts with the windows registry as well as a few files on the hard drive. I think this is where the problem is. Unfortunately, I did not write the code, so I'm not certain where the problem could be. I have always been able to easily troubleshoot issues with code when running the full Labview software, but with the compiled code, you can't see the block diagram.
Any help would be greatly appreciated.

Running DS-5 armcc compiled code (PIC) under Windows EC 2013

Hi All,
i just wanted to know if it is generally (officially) supported to run code that is compiled via the armcc (5.03) from DS-5 under Windows Embedded Compact 2013. Or if this is discouraged (reasons?).
The problem i have:
The bootloader contains some code that must be run during Windows EC Startup. So this code is loaded from the Flash, copied to RAM (reserved and commited via VirtualAlloc and marked as executable) and then the functions are called via FunctionPointers.
The code is compiled and linked as position independent and the stack base register is set accordingly before any function is called via pointer and reset when it returns.
This works in about 9 out of 10 tests without problems. But sometimes i get all sort of exceptions (Data Abort, Prefetch Abort, Unknown Instruction, ...). Most (if not all) of the time they occur when the position independent code runs on one of the two
cores.
The code runs on an i.MX6DQ (dual).
If i only enable one core, i can't reproduce the problem (i assume that multicore-handling and multithreading in WinEC 2013 Update 10 is really well tested and works without problems, so this can't be the real reason).
I've thoroughly checked and debugged the code, i'm really sure there is no illegal access or other problem with the code itself.
Could it be a problem to call code compiled via DS-5 armcc? I've compared assembler code that Visual Studio/Platform Builder generates with code that DS-5 generates (but i'm no assembler expert). I can't see any obvious special code that is added by Visual
Studio/Platform Builder (i.e. that functions need) that is not there in the DS-5 code.
Best Regards
Sebastian

So I think you could be able to image some code for ROM from another compiler and without knowledge of Windows CE. However, if the code will be called from Windows CE, this becomes more difficult requiring very careful isolation from the
MMU state, processor state, kernel/user mode, etc. Code that works great when called from the bootloader might not work at all from Windows CE itself. The main problem with mixing code from different compilers is the object file format and conventions for
entry and public names. Very unlikely that you'd be able to "link" code from any other compiler with PB-compiled code.
You might think about the x86 image which can easily call BIOS from the bootloader but which can't even begin to call BIOS from CE itself. The problem isn't the compiler (which is different), but the operating environment differences and assumptions.

How to retrieve constants value from compiled code in jar file?

Hi everyone,
I've been looking for a way to solve this for a week now, without any much success... and I've finally decided to ask the Java gurus for a solution! :-)
Here's what I am basically trying to do:
I have several jar files in which there are only compiled code (.class).
In every class, there are 2 constants (declared as static final String) that I would like to retrieve (one is the version and the other the date of the last modification).
My goal is to print a list of all the classes in the jar files with the values of these 2 constants for each class.
The solution that I have right now to do this does not work properly: for now, I read all the elements of the classpath, check if these are jar files, and if so, I look into each one and load all the classes one by one and print the results.
The problem with this is that it uses the method Class.forName(className) and as some classes are unfortunately present in many jar files (2 or 3 copies), once the classes have been loaded, then it won't be "reloaded".
Without the possibility to "reload" these classes, I cannot see inconsistencies in the versions of the classes present in the jar files.
I have read many articles, and I thought that I could then use a custom classloader and create a new instance of this classloader for each jar file.
2 problems with this:
- according to many posts in the different forums I have read, the jar files should not appear in the CLASSPATH (but this would be easier for me if I could use it...)
- some classes will not be loaded if some classes (present in other jar files) are not loaded... and this makes things really really complicated to implement...
So, I thought that I was maybe doing this the wrong way, and that there might be an easy way out of this...
In fact, I do not need to load the classes... all I need to do, is take a sneak peek at the constants and print their values... and that's it!
Somehow, I think that this is possible to retrieve the values of compile time constants (declared as static final String) as I can see that with Eclipse (when opening a jar file).
So, my question is: how can I do that within my java application?
Or maybe there is another easier solution to do what I need?
Thanks in advance for your help!

Error during distribution for compiled code generation-Reply

Hi,
Looking at your error messages, it looks as though your build is failing during the code generation phase of an autocompilation. To determine why the code generator crashed, either look in the $FORTE_ROOT/log/forte_ex*.log files or don't use autocompilation and use fcompile.
There are many reasons why the code generator could crash. Some of the things I've come across are running out of memory and trying to find invalid classes.
If its the invalid class problem you'll find a message like:
Generating code for partition BLTCustomWindow_cl0_Part1.
ERROR: Exiting due to following exception:

The solution for this instance is to clean up the invalid classes using the c4tstdrv utility.

Integrate the changes to the workspace, start the build again and this should have cured the problem.
However, its hard to know what the cause of your problem is without seeing the output in the log files.
Good luck.

Hi,
I'm doing application distribution for my application using a fscript
script and am forcing compilation on 2 of my partitions.
This I have been doing from quite sometime successfully. Recently I
developed a new service and plugged it into my application for
deployment.
I'm successfully able to distribute & deploy the interpreted code. But
I'm getting a long list of system errors when I try doing distribution
for compiled code. And I see only one of the .exe generated instead of
two because of which I'm unable to go ahead with installaion. I would
appreciate if anybody let me know why this's happening ?. The following
is the main chunk of this error list.
Thanks in advance.

Compiled Code Error Running Excel

Writing to Excel works fine with source code but gives this error with compiled code:
Open VI Reference in Dispose Report.vi->Write_to_Excel.vi->Golden_Thread_V2.vi<APPEND>
VI Path: <b>C:\Golden Thread\Golden Thread V2.2.exe\Excel_Quit.vi</b>
Built Application or Shared Library (DLL): Make sure all dynamically loaded VIs were properly included in the build specification for the application or shared library.
Any thoughts???
Thanks.

Hi Steve,
if you use for example the "Append Table to Report.vi", then you have in the "Excel" case a dynamic loaded vi, also in the "New Report.vi". See the picture.

Compile code in a file

i have some java codes in my "fl.txt"(c:\fl.txt). these are;
public class file_{
public static void main(String args[]){
System.out.print("hello world");
}i want to compile these code from my program(i am building it with java) at runtime.. how can ii do that.i think i need to use runtime.exec() method but i dont know how can i compile these codes in a file....

It is possible to dynamically compile code from within a running Java program,
but you should have a damn good reason for doing so.
Check out the documentation for javac: http://java.sun.com/javase/6/docs/technotes/tools/windows/javac.html
<quote>
javac supports the new Java Compiler API defined by the classes and interfaces in the javax.tools package.
Example
To perform a compilation using arguments as you would give on the command line, you can use the following:
JavaCompiler javac = ToolProvider.getSystemJavaCompiler();
int rc = javac.run(null, null, null, args);This will write any diagnostics to the standard output stream, and return the exit code that javac would give when invoked from the command line.
You can use other methods on the javax.tools.JavaCompiler interface to handle diagnostics, control where files are read from and written to, and so on.
</quote>
If you are using an older version of Java, check out the documentation to see the old interface to do this (com.sun.tools.javac.Main).

Actually, the jar and class file was in the same path...
Thus, what the correct command i need to run the my code?Then your classpath would be .;mysql.jar (or whatever the heck the name of the connector was).
So java -cp .;mysql.jar foo.bar.MyClass

Compiler Code Generation API

I would like to ask if you guys could make a Compiler Code Generation API. This would allow developers who would like to fine-tune details you guys probably don't have time to do, for projects we think its important on. Specifically with [Bindable] and {} code generation.
I would like to be able, and many others I'm sure, to turn Binding on/off (conditional binding), and add more complicated expressions, but that's currently impossible, unless I rewrote the core UIComponent and everything. Or unless I had access to the generated code through a nice API which shouldn't take you guys long at all: you already are generating lots of code and have templates for it, I would just like to ask for easy access to those templates.
Please let me know what you think. Thanks a lot for your time.
Lance

It's something we've thought about but it's not a high enough priority right now. Certainly a feature that folks could think about implementing on their own and contributing back though. It tends to be more complicated than you'd think though

Java.lang.NoClassDefFoundError: com/sun/j3d/utils/applet/MainFrame         at HelloUniverse.main(Compiled Code)

I'm getting this error
java.lang.NoClassDefFoundError: com/sun/j3d/utils/applet/MainFrame
at HelloUniverse.main(Compiled Code)
I receive this error when I try to run the demos that are in the /usr/java1.1/demo folder.
I followed the directions to install java3d. I installed the java3d binary in the top part of
the JDK directory then ran the binary. Everything installed o.k., but I cannot run
any of the demos. I also have J2SE 1.2.2_05a, JDK 1.1.8_10, and.
JRE 1.1.8_10 installed. My operating system is SunOS 5.6, Solaris 2.6. My workstation
is an Ultra 5 with 374mb ram.
Here is part of the install intructions.
Place the java3d1_2-solsparc.bin file into the top level directory
of the JDK you wish to install Java 3D into. Execute the
java3d1_2-solsparc.bin file (ex: sh java3d1_2-solsparc.bin).
After installation, you may remove this file.
The Java 3D(TM) SDK includes several demo programs that can
verify correct installation. Assuming your Java 2 SDK is installed
at ~/Solaris_JDK_1.2.2_05, try the following:
cd ~/Solaris_JDK_1.2.2_05/demo/java3d/HelloUniverse
java HelloUniverse
Note: Many more demos are available under the demo/java3d/
directory. Some of the demos require a maximum memory
pool larger than the default in java. To increase the
maximum memory pool to 64 meg, add the following command
line options to java or appletviewer:
java: -mx64m
appletviewer: -J-mx64m
You do not need to include the J3D jar files in your CLASSPATH,
nor do you need to include the J3D shared libraries in your PATH.
You should include "." in your CLASSPATH or ensure that CLASSPATH
is not set.
I'm not sure how to set set/unset the CLASSPATH and I'm not sure if I was supposed to
place the binary file in the /usr/java1.1 or /usr/java or /usr/java1.2 directory.
Can anyone help?

-- If jar size isn't an issue, I recommend using thick "weblogic.jar" instead of the thin "wl*.jar" jars. The thick jar is a better performer, is used by more customers, and has more features. Otherwise:
          -- It might help to use the thin client jars from a later service pack - several service packs have been released since SP2, or you might even try using jars from a recent 9.2 SP or even 10.0.
          -- Also, check to see if the 1.4.2 JVM is up-to-date and/or try switching from the Sun JVM to the JRockit JVM (or vice-versa).
          -- Finally, it might help to check if your XP environment matches your Linux environment (JVM command-line, classpath, etc).
          -- Also: The IIOP newsgroup may also have some advice. The thin client uses the IIOP protocol even when a "t3:" URL is specified by the application.

Does PLX file have any compiled code

What exactly is a plx file. I created a plx file giving the COMPILE_ALL option as
NO. I saved the plx and the pll in the libraries directory .
When i run my form i can see the changes. Does the plx have any code or is it just
a referece to the pll file.
thanks

the point with the security is a good point. I appended it in my blog:
our projects are normally applications for customers and never standard-software. So we have no problem with security. The application server with the deployed forms and libraries is secured as strong as the database, so that only admins have access.
### this is added in the blog - try the example on your machine ###
Other developer say: plx is only the compiled code, so nobody can steal my sourcecode or something valuable from within the code - in that case try this example:
Create a library with a package and this variable:
<pre>
PACKAGE Const IS
HiddenPW CONSTANT Varchar2 (100) := 'HiddenPW';
END Const;
</pre>
Generate the plx and open it in an editor. Search for "HiddenPW". You'll find the name of the variable and the string associated to the var. That's not save in my eyes. Only the sourcecode is hidden. I think, that a pll on an Application Server is secure enough.
If the application is standard software and is not for free, then you can use the plx-technique :-)

You are right, if we are giving priviledges explicitly , it works .
can't we do anything else because in this way at start of the financial year we have to grant so many explicitly priviledges .Yes, don't create database objects that are named based on data (e.g. names with months and years in them).
Data should be inside the table and not used to distinguish the table.

Servicegen / clientgen : Really annoying lack of debug in compile code

WLS7.0 SP1
Unless I have missed something silly, there seems to be no way to influence the
compile options of the code compiled by servicegen and clientgen - and by default
they are not compiled with debug info.
Its in clientgen that it is a particular pain. Because there is no debug info,
you get quite poor intelliSense with dev toos and also no line numbers in stack
traces.
Is there a way around this?

Are we talking about the same spec? The LineNumberTable attribute sounds like debug info to me, and it's defined at 4.7.8 of the JVM spec. Yes and no. I don't think that used to be in there.
In any case, for the stratum parameter of of Location.lineNumber (defined in the JDI section of the JDK docs) to be useful, the stratum for a line number has to be recorded somewhere such that Location.lineNumber can recognize and access it.Given that my response above was a guess, and you thought it sounded likely just get a real class file reader and look to see what values are in the attribute section. If it is there, either as some odd variation of the debug stuff, or another type of attribute then problem solved. If not there then the reader should help to determine where it actually is.

PXIe-8101 Unable To Compile Code

Hello,
My system is a PXIe-1065 chassis (I've also had the same issue in the PXIe-1082 chassis), PXIe-8101 controller with Windows 7 installed by NI, and the following instruments:
DMM PXI-4071, Power Supply PXI-4110, DAQ PXIe-6356, Timing Card PXIe-6674T, and Motion Control PXI-7332.
I also have a PXIe-8361 which I will use on occasion and will be what I use in the long term.
Now for the actual problem. What happens is I'll put together some code in labview using the instrument driver VI's and everything will work fine. I can make VI's that call subVI's that call the instrument VI's and it works great, but if I double click on an instruments VI and then try to look at the block diagram, for example, opening "DAQmx Create Channel (AI-Voltage-Basic).vi" it seems to break the code. Initially it won't say anything but once I hit the run button the arrow will change to the broken gray arrow and will state that the code failed to compile (this is without actually changing anything with the VI, I open it and look at what it is doing).
Also any code I've written that called that VI will now get the same error, if I click show error it will bring up whatever window I was looking at last, so if I was looking at the front panel, then clicked show error it would just bring up the front panel again without highlighting anything. If I create a new file and build a small vi that uses the instrument drivers it works fine, if I copy the vi's from the broken code and paste it into the new file it will fail with the same error.
It doesn't have this behavior with all the instrument VI's but will happen with some. I mentioned it happens with "DAQmx Create Channel (AI-Voltage-Basic).vi" but then it doesn't happen with "DAQmx Timing(Sample Clock).vi". I haven't gone through and checked exactly which VI's it happens with but it seems to happen with other instruments drivers as well, not just for the DAQ. It also only seems to happen when using the PXIe-8101. If I connect it to a computer this issue doesn't pop up. My company primarily controls the chassis using MXI cards so we don't have any available embedded controllers I could swap in to see if it still happens.
It's not a big issue as looking into the instrument vi's isn't necessary for me to do my job, I just do it to try to better understand what exactly is happening but it is something I'm curious about.
DISCLAIMER: I'm a hardware engineer so I may not be familiar with some concepts/terminology/best practices so... patience is appreciated
Solved!
Go to Solution.

At the time I first noticed this error I was just starting to use labview, so I simply avoided opening that vi, now I've been working with labview for about 9 months. I haven't been working with it consistently, not all my projects require it, but I would say I've spent at least half my time working with it.
Well I seem to have recorded it slightly off. So when I looked into the DAQmx vi it gave an error and when I clicked show details it gave the following:
When I tried to exit it asked me if I wanted to save the changes, I chose defer decision and eventually chose do not save. I closed labview and reopened the VI, tried to run it and it gave the error:
I selected show error and it gave:
Then where it said it failed to compile was within another vi in the same project. When I first opened it it said SubVI is not executable. When I clicked show error it took me to a VI that had the DAQmx vi in it and it was saying VI failed to compile.
I've attached the SubVI from which I opened the DAQmx. It's a basic vi to read analog data. Is that what you meant for screenshots?

You can compile it using Runtime.exec() and invoking the command as used from command line; or refer to reply #1 on http://forum.java.sun.com/thread.jspa?threadID=695534
