I've got a follow-up question about cross-compiling for dSpace. My
Toolchain file so far:
set(CMAKE_SYSTEM_NAME dSpace)
list(APPEND CMAKE_MODULE_PATH ${CMAKE_CURRENT_LIST_DIR})
file(TO_CMAKE_PATH "C:\\Program Files\\dSPACE RCPHIL 2016-B" DSPACE_TOOLS)
set(DSPACE_PPCTOOLS ${DSPACE_TOOLS}/Compiler/PPCTools)
find_program(CMAKE_C_COMPILER NAMES ${DSPACE_PPCTOOLS}/bin/mccppc.exe)
find_program(CMAKE_C_COMPILER NAMES ${DSPACE_PPCTOOLS}/bin/cccppc.exe)
find_program(CMAKE_MAKE_PROGRAM ${DSPACE_TOOLS}/Exe/DSMAKE.EXE)
set(CMAKE_FIND_ROOT_PATH ${DSPACE_PPCTOOLS})
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
CMake is actually able to locate the C compiler (called "mccppc.exe") and
CMake thus tries to compile a test program ('CompilerIdC.c'). I can compile
this source file 'by hand' with said compiler. However, from CMake (which
automatically uses MSBuild.exe), I get the error output below.
How can I circumvent MSBuild.exe and/or the attempted loading of the SDK?
Do I forget to set some other important variables (e.g. CMAKE_MAKE_PROGRAM
seems to be ignored?)
The C compiler "C:/Program Files/dSPACE
RCPHIL 2016-B/Compiler/PPCTools/bin/mccppc.exe" is not able to compile a
simple test program.
It fails with the following output:
Compiling the C compiler identification source file "CMakeCCompilerId.c"
failed.
