sha.cpp:294:2: error: invalid instruction mnemonic 'movsl'

[Manish Gautam]

I was trying to compile  cryptopp562 using command "make CXXFLAGS=-m32" 
I gave following errors:

sha.cpp:294:2: error: invalid instruction mnemonic 'movsl'

Can somebody help me?

This looks like a Clang-ish error message from inline assembly. What is the platform, and what is the compiler?

Also note that we improved Clang support at Crypto++ 5.6.3. It started at 5.6.3 and continued after as encountered more issues with the integrated assembler. Prior to 5.6.3, I believe -DCRYPTOPP_DISABLE_ASM was added to CXXFLAGS to avoid all the problems with the integrated assembler. You might want to consider using Crypto++ 5.6.3 or Master.

I tried 5.6.3, I am getting follwoing errors

Is there any reason you're trying to build "fat" binaries? It used to make sense several years ago, and Apple still allows that - but not any more. Now no system binary is "fat" (they're all 64-bit), and you'd be much better off with just "-arch x86_64".
