[Bf-committers] Building the latest trunk/master on Mac

[Varanda - CG Labs]

Thanks Jens,

It is not clear yet to me: shouldn’t turning off WITH_OPENMP in ccmake makes the build happy ?
How can I override gcc in CMakeLists.txt to point to clang-imp? There is no visible ease line likes setting CC or CXX = ABC

The closest definition regarding to the compiler there is:

		if(${XCODE_VERSION} VERSION_EQUAL 4 OR ${XCODE_VERSION} VERSION_GREATER 4 AND ${XCODE_VERSION} VERSION_LESS 4.3)
			# Xcode 4 defaults to the Apple LLVM Compiler.
			# Override the default compiler selection because Blender only compiles with gcc up to xcode 4.2
			set(CMAKE_XCODE_ATTRIBUTE_GCC_VERSION "com.apple.compilers.llvmgcc42")
			message(STATUS "Setting compiler to: " ${CMAKE_XCODE_ATTRIBUTE_GCC_VERSION})
		endif()

I am not familiar with cmake though. Some more digested information would be very welcome.

Thanks a lot,
Varanda
