When I execute sh build.sh，an error occurred:

Should I use a specified version of gcc? or add some options to build.sh?
Current version of my gcc is like below:

Thread model: posix
gcc version 9.4.0 (Ubuntu 9.4.0-1ubuntu1~20.04.1)
ubuntu 20.04 may not support avx vnni instructions.
update to 22.04.
a newer clang-13 compiler fix this issue too.

gcc --version

after sudo apt-get install clang-13
and use
gcc=clang-13
g++=clang++-13
compile success, result is right, avx_vnni dp4 works about 2x fast as FMA_f32, not 4x :
