Kefu Chai 38e7686a37 cmake: pass cflags to disutils using CC instead of CFLAGS ... in python's distutils.ccompiler, linker_exe is composed using CC instead of LDFLAGS. the latter only effects how it builds (shared) library. and put CMAKE_C_FLAGS into the cflags for the compiler for building python C extensions, it's more consistent this way. more importantly, if we build with ASan enabled, the canary program, a.k.a. rados_dummy.c, won't link without proper CFLAGS. without this change, rados.so fails to build with errors like: /usr/bin/ld: /var/ssd/ceph/build/lib/librados.so: undefined reference to `__asan_stack_free_10' /usr/bin/ld: /var/ssd/ceph/build/lib/librados.so: undefined reference to `__asan_report_exp_store8' ... ... clang: error: linker command failed with exit code 1 (use -v to see invocation) Link Error: RADOS library not found make[3]: *** [src/pybind/rados/CMakeFiles/cython_rados.dir/build.make:57: src/pybind/rados/CMakeFiles/cython_rados] Error 1 Signed-off-by: Kefu Chai <kchai@redhat.com>		2018-10-22 14:40:03 +08:00
