My system is i686, and I found there is no -march=i686 by default. I found this in CMakeCache.txt CMakeCache.txt://Test _OPENTHREADS_ATOMIC_USE_GCC_BUILTINS CMakeCache.txt:_OPENTHREADS_ATOMIC_USE_GCC_BUILTINS:INTERNAL=1
CMakeCache.txt:_OPENTHREADS_ATOMIC_USE_GCC_BUILTINS_COMPILED:INTERNAL=TRUE CMakeCache.txt:_OPENTHREADS_ATOMIC_USE_GCC_BUILTINS_EXITCODE:INTERNAL=0 Is there a problem? I'll add CXXFLAGS as you mentioned and compile again.
