Hi,
I am working with CMake 2.8.3 and trying to set up a cross-compiling toolchain
for an ARMCC that runs on a Windows system.
What I´ve done up to now is that I set up a toolchain file that I am using in
combination with nmake makefiles.
This file defines:
SET( CMAKE_C_COMPILER "${ARMCC_ROOT}/armcc.exe" )
SET( CMAKE_CXX_COMPILER "${ARMCC_ROOT}/armcc.exe" )
# specify the compile command
SET( CMAKE_C_FLAGS <SOME FLAGS HERE> )
SET( CMAKE_CXX_FLAGS <SOME FLAGS HERE>)
# specify the linker and its options for creating static libraries:
SET( CMAKE_AR_FLAGS "${SOME_LINKER_FLAGS} -o <TARGET> <OBJECTS>")
SET( CMAKE_CXX_CREATE_STATIC_LIBRARY "${MY_LINKER} ${CMAKE_AR_FLAGS}")
SET( CMAKE_C_CREATE_STATIC_LIBRARY "${MY_LINKER} ${CMAKE_AR_FLAGS}")
# specify the linker for linking applications
SET( CMAKE_C_LINK_EXECUTABLE "${MY_LINKER} ${MY_LINKER_FLAGS_APP} " )
SET( CMAKE_CXX_LINK_EXECUTABLE "${MY_LINKER} ${MY_LINKER_FLAGS_APP}" )
Now comes the interesting part...
When I start the cmake "first-time" configuration process on a clean build
directory,
- The compiler detection build uses the settings above
- The "compiler works" build does not use them and fails
- The ABI check build does not use them and fails
Do you have a hint for me what is going wrong?
As the compiler detection build succeeds and uses the flags, I assume that it
can be a bug in CMake´s detection modules.
What do you think?
Regards,
Alex
