Oh yeah,... OS X ships with an early 2000's assembler. Uri knows more about this than I do, but when using a modern GCC on OS X, you should add -Wa-q. That tells GCC to use Clang's integrated assembler. The integrated assembler can handle modern ISAs (depending on the version of the LLVM back end). Clang's integrated assembler has some problems because it can't consume .intel_syntax. It can't even handle a simple negate in Intel syntax. So in the makefile we add a define to disable Intel code paths (https://github.com/weidai11/cryptopp/blob/master/GNUmakefile#L310): # Tell MacPorts GCC to use Clang integrated assembler # http://github.com/weidai11/cryptopp/issues/190 ifeq ($(GCC_COMPILER)$(MACPORTS_COMPILER),11) ifeq ($(findstring -Wa,-q,$(CXXFLAGS)),) CXXFLAGS += -Wa,-q endif ifeq ($(findstring -DCRYPTOPP_CLANG_INTEGRATED_ASSEMBLER,$(CXXFLAGS)),) CLANG_INTEGRATED_ASSEMBLER := 1 CXXFLAGS += -DCRYPTOPP_CLANG_INTEGRATED_ASSEMBLER=1 endif endif I thought it was present in Crypto++ 5.6.5, but I guess not. So the short of it is, try adding -Wa,-q. If CRYPTOPP_CLANG_INTEGRATED_ASSEMBLER is missing when source files are compiled, then add the define, too. Something like: $ CXXFLAGS="-DNDEBUG -g2 -O2 -fPIC -march=native -Wa,-q" make -j 8 And don't believe a compiler that claims to be GCC by defining __GNUC__. The LLVM developers have been told several times to stop doing it. LLVM's fake GCC and MSVC support is so bad, it is the reason we don't support LLVM on Windows. It took Uri and I several months to work around all the LLVM issues on Linux and OS X. We were not subjecting ourselves to the same on Windows.
