I can't build glibc on computer that does not support evex 512 instruction with default configuration
zcj5918 opened this issue · comments
I just use configure and make -j, yet cannot build gblic 2.37, I think the reason is my E5-2678v3 CPU does not support avx512 instruction set. Can I disable avx512 instruction set before compiling?
When I use make, I received these:

My Environment:
g++ 7+
Ubuntu 16.04.7 LTS E5-2678V3 X 2 nvidia 2080Ti x2
From what I know vpcmpneqb is based on avx512 set, can anyone else kindly tell me how to disable avx512 before compiling?
Hello. I know your comment too old, but I had same issue when working on old CentOS 7. I've upgraded GNU binutils (This contains new version of GNU Assembler) by compiling from it's source and it worked.
try to run configure with --disable-avx512
