I did another test in v5 using 7.3.1. The command gmake is invoked successfully at the beginning of the build, and 100% build could be completed now. Then, the linker stalls (runs forever) at this 100%build. If I stop the build manually, I get the error:
--------------------------------------------------------------------------------------
!CommandLauncher.error.commandCanceled!
Error: Program "C:/ti/ccsv5/utils/bin/gmake" is not found in PATH
...
--------------------------------------------------------------------------------------
I am guessing this should be something about the environment variable related to the linker, but this "gmake" path can be strangely found in the beginning of the build.
