TMS320F280049C: How to use CCS v11.2 compiler to compile a .c file?

I don't see how the CCS project issued these build commands ...

There are two commands.  The first one is a cd (change directory) command.  The build of a CCS project never uses cd.  The second command is an invocation of the compiler cl2000.  It compiles one source file and then links the program.  A CCS project uses the compiler, but never in that manner.  It always compiles the files, then links with a separate invocation of the compiler.

The immediate problem is that the compile command does not indicate where to find the RTS library include files like <math.h>.  You need to add an option similar to ...

--include_path=C:\ti\ccs1120\ccs\tools\compiler\ti-cgt-c2000_21.6.0.LTS\include

When I build the project you attached, the build succeeds.  Here are the contents of the Console view ...

This build works as I describe above.  The project is configured to use compiler version 16.9.2.LTS.  I have this compiler installed in a non-standard place C:\ti\compilers.  I configured CCS to search this directory for compilers any time a new project is added.

Thanks and regards,
