src/arch/posix/CMakeLists.txt and -DFORTE_LITTLE_ENDIAN [message #1827830]

Hi,

We have a little endian build (on host compiler platform for dev/test work) and a big endian build (for ColdFire target). For both to co-exist, we moved the -DFORTE_LITTLE_ENDIAN from src/arch/posix/CMakeLists.txt to a "toolchain-${target}.cmake" file.

Then in the "setup-${target}.sh" file the host specific build is executed:
cmake -G "Unix Makefiles" -DCMAKE_TOOLCHAIN_FILE=./toolchain-${target}.cmake $NOJA_CMAKE_VARS ../../

What do you think is the best way of handling this endian configuration in the forte code base?

Thanks

Hi,

I think that endian handling as so many other things would be best suited as cmake configuration option (maybe in the advanced section), which then generates appropriate code in the forte_config.h. Cmake code in the different architectures could then already check if it is set and even provide sensible default values.
