Failing to build from git master on Arch Linux #18

Open glitsj16 opened 4 years ago

glitsj16 commented 4 years ago

Hi, after noticing recent commit activity I held back reporting broken build failures on Arch Linux for a while, assuming things would sort themselves out. Today I tried another build from latest git at commit https://github.com/otrv4/libgoldilocks/commit/d07cb5b423995bae1155702aa949846c95d855c1. Here are my observations:

...
./goldilocks_gen_tables > GEN/goldilocks_tables.c || (rm GEN/goldilocks_tables.c; exit 1)
/bin/sh: line 1: 104188 Illegal instruction     (core dumped) ./goldilocks_gen_tables > GEN/goldilocks_tables.c
make[2]: *** [Makefile:1333: GEN/goldilocks_tables.c] Error 1

make[1]: *** [Makefile:420: all-recursive] Error 1

OS: Arch Linux

$ pacman -Q gcc make gcc 9.3.0-1 make 4.3-1

I've just built one with PKGBUILD, and found: variables.am:ARCHFLAGS = -maes -mavx2 -mbmi2 #TODO

So it'll be built with AVX2 on, but my machine is a Sandy Bridge, so get a SIGILL.
