It's pure assembler issue, not compiler. You can compile the module with gcc 3.x if you wish (I actually do) as long as you have new enough 'as' on your $PATH. >> I've been trying to build OpenSSL-1.0.2a on an outdated SLES11 system. >> It fails unless I configure with "no-asm".

I mean it might have to be adjusted as $1>=2.20 instead of 2.19. While AVX support was added in binutils 2.19, they might have omitted specifically vpclmulqdq. Can you confirm if it works if you replace 2.19 with 2.20? _______________________________________________ openssl-dev mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-dev
