XDC runtime error: can't find program 'app.xe66's linker command template file: 'null' along the path

Additionally, if I issue a secondary project build the above error no longer happens, but rather other build errors happen due to the Program.global.XXXX for static mailboxes, queues, etc. are *not* being defined when compiling project source files.

I am confident that this secondary problem is rooted in the original XDC error posted earlier.

How do I fix my project to resolve the XDC error to autogenerate the needed compiler and linker input files?

At the moment I am stuck.

I would greatly appreciate any help to remedy this issue.

Thanks in advance,

Another piece of information is that both "Platform" and "Program" entries within the XGCONF Outline view have a RED dot whereas all the other entries are BLUE

The "Platform" say DO NOT MODIFY, but upon inspecting its Basic/CPU I see that dataMemory and stackMemory are not pointing to the correct memory segment DDR3_CODE as was configured within the "custom" platform.  The codeMemory is correctly pointing to DDR3_CODE.  Another observation is the L2Mode shows 0k and not the 512K that it's supposed to be.

Other changes made to the "custom" platform do get detected by the XGCONF editor, but the above are still incorrect.

Why aren't all the "custom" package platform settings correctly detected by XGCONF?

Maybe this is a related issue to my XDC tools generation problem.

George,
the linker script template and the build platform are related but they are not the same thing. If you have a linker script template that you want to use, you should set Program.linkTemplate to point to that file. If you want the build platform to set Program.linkTemplate, there is no need to set Program.linkTemplate to "null" because it is "null" already. However, it should still work if you set it to "null". What really happens if you try to set it explicitly to "null" is that XGCONF tries to set it to the string "null" instead of the value null. If you check your config script you'll probably see the line:
Program.linkTemplate = "null";
To fix it, either remove the line completely, and any other previous line that sets linkTemplate or just remove the quotes:
Program.linkTemplate = null;
That's a bug in XGCONF and I'll file a bug report to track it.
Edit: the filed bug is https://bugs.eclipse.org/bugs/show_bug.cgi?id=407602.

Also, you can't change the build platform in your config script. You already set up your platform to SaturnV_C6655, you can see it from the configuro command line. Please remove the line that invokes useModule on "SatrunV_C6655" from your cfg script and try building again. I am guessing you used the Platform Wizard to create your custom platform. You can use it to view your platform just to be sure that the settings still show up correctly in the platform. Use Tools->RTSC Tools->Platform->Edit/View to open your platform.

Let me know what happens after you fix these two lines from the script.

Sasha,

After using XDCscript Editor...

Removed quotes around "null" from... Program.linkTemplate = "null"; to... Program.linkTemplate = null;

Still failed, but differently...

**** Build Finished ****

I then removed quotes around "null" from... Program.sectionsTemplate = "null"; to... Program.sectionsTemplate = null;

NOW THIS IS FIXED!!!  The quotes present in the .cfg file visable within XDCscript Editor but not XGCONF was indeed the problem.

I also removed the useModule for the "custom" platform as you recommended and things are much happier now.  This was an attempt on my part to see if that fixed things.

I still have an issue wherein the compiler is *not* resolving XGCONF statically created Program.global identifiers such as named Heaps, LoggerBufs, Mailboxes, Queues, Semaphores, and Tasks.  How can I fix this?

If you can answer that here I'd appreciate it or I will re-post this question in this or another forum as you recommend.

Thanks,

-George

Sasha,

Adding the <xdc/cfg/global.h> to my source C files remedied the compiler unresolved references to the statically created global entities being created by XGCONF.

Thanks,
