I am working to build a Code Composer Studio project using cmake, which is new to me. It builds successfully under Linux but I am struggling to get it to work under Windows. The cmake command executes without issue, but make fails during the very first C object at the very first #include with the error code
fatal error: could not open source file "stdbool.h" (no directories in search list)
I'm using the libraries included in CCS's compiler (c6000_7.4.15), and that whole folder is included in the CSS project. I include it in cmake as well. In my .cmake file:
set (CCS_ROOT ${CCS_ROOT_V6_WIN} CACHE PATH "code composer install directory")
set(CGT_COMPILER_ROOT ${CCS_ROOT}/tools/compiler/c6000_7.4.15 CACHE INTERNAL "DSP Compiler Root")`
And in the CMakeLists.txt file:
set (COMPILER_INCLUDE ${CGT_COMPILER_ROOT}/include)
INCLUDE_DIRECTORIES ("${COMPILER_INCLUDE}")
Why can the header files not be opened when they're linked in the project and CMake can find them just fine?
EDIT: The directory structure had been changed underneath me, so I took the opportunity to add all of the external files directly into the project to make it completely platform-independent. That way, since the project is managed by our Git repository, users won't have to install the CSL or any other programs to build the project. This also means that paths to libraries and header files will never change between revisions and environments.
Unfortunately, this has not solved my problem. The project continues to build in Linux while failing to ind the very first included header file. I also notice that, under Windows, it cannot find my own header files unless I provide a relative path, e.g. #include "../Common.h" I can get make to find stdbool.h if I provide an absolute path to the compiler directory, but that exposes a web of additional broken links between files.
As a side note, the project builds successfully within Code Composer Studio, so I am assuming that this isn't an issue with my specific Windows environment nor with the code within the project itself.
This seems to be an issue with gcc.exe. I set an environment variable CC to the path of a different compiler (in my case a TI compiler) within my build script and that fixed the problem.
