[x86-compile] error: impossible constraint in ‘asm’

[alanzhai219]

e7176cf causes such error. inline code cant work properly in some CPU.

You can append -DPPL_USE_X86_AVX512=OFF to the cmake command-line to separate the AVX512 codes.
But in this case, the error is not about the CPU but the compiler.
Can you tell us about your environment?
Including OS, compiler and the command-line?

PPL_USE_X86_AVX512 work for me.

os : ubuntu20.04
gcc: 9.3.0
cmd: ./build.sh -DHPCC_USE_X86_64=ON

I cannot reproduce the compile error with a similar environment.
I have built the lastest master successfully with:
CPU: i7-10700K
OS: ubuntu 20.04.2
gcc: 9.3.0
cmd: ./build.sh -DHPCC_USE_X86_64=ON

Can you show the entire error message by GCC?

Hope it is not late to say sorry. I think my description above may guides wrong direction.
In brief, try to replace 'Release' with 'Debug' in build.sh and then rebuild your master.

Hello, I fix the compile issue with bulid type Debug in #109 .
You can try my forked repo first or wait for the manager to accept the merge request.
