Regards, Jonathan For: find_program(CMAKE_AR NAMES ${_CMAKE_TOOLCHAIN_PREFIX}ar${_CMAKE_TOOLCHAIN_SUFFIX} HINTS ${_CMAKE_TOOLCHAIN_LOCATION}) It seems the ${_CMAKE_TOOLCHAIN_LOCATION} hint is not used when CMAKE_FIND_ROOT_PATH_MODE_PROGRAM is set to ONLY. You are right. The CMAKE_FIND_ROOT_PATH is used also as base for the HINTS paths. You can use _CMAKE_TOOLCHAIN_LOCATION to pass NO_CMAKE_FIND_ROOT_PATH to the find_program calls: set(_CMAKE_TOOLCHAIN_LOCATION NO_CMAKE_FIND_ROOT_PATH) This should work but I am not sure if it is a good solution. I prefer setting documented variables rather than hacking the undocumented _CMAKE_TOOLCHAIN_LOCATION variable to add the NO_CMAKE_FIND_ROOT_PATH flag for FIND_PROGRAM. I think it is a issue in cmake and the _CMAKE_TOOLCHAIN_LOCATION don't work with CMAKE_FIND_ROOT_PATH_MODE_PROGRAM set to ONLY. I have open an issue in cmake to get some feedback. The could patch all find_program calls in CMakeFindBinUtils.cmake modules: - find_program(CMAKE_AR NAMES ${_CMAKE_TOOLCHAIN_PREFIX}ar${_CMAKE_TOOLCHAIN_SUFFIX} HINTS ${_CMAKE_TOOLCHAIN_LOCATION}) + find_program(CMAKE_AR NAMES ${_CMAKE_TOOLCHAIN_PREFIX}ar${_CMAKE_TOOLCHAIN_SUFFIX} PATHS ${_CMAKE_TOOLCHAIN_LOCATION} NO_DEFAULT_PATH NO_CMAKE_FIND_ROOT_PATH) + find_program(CMAKE_AR NAMES ${_CMAKE_TOOLCHAIN_PREFIX}ar${_CMAKE_TOOLCHAIN_SUFFIX}) Additionally there is a second issue as cmake fails to add the paths to the CMAKE_C*_COMPILER variables in CMakeDetermineC*Compiler modules and thereby couldn't set the _CMAKE_TOOLCHAIN_LOCATION. But this is a issue of oe as we should pass the full path of the compilers. ___ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
