Cannot build it. AVX problem about vectorsimilarity

[DvirDukhan]

hi @somsomers
Thanks for reporting

1. If I understand correctly from the build log, you are using GCC version 6 /usr/lib/gcc/x86_64-linux-gnu/6. We require modern gcc, e.g. version 10 and up. Can you verify your GCC version? Also, you can follow https://github.com/RedisAI/VectorSimilarity#build for requirements. In addition, we have provided a docker image for dev/build purposes (see https://github.com/RedisAI/VectorSimilarity#docker-build ) Waiting for your input to understand any further checks required on our side.
2. If you want, you can try running make VECSIM_MARCH=x86_x64, for generic x86_64 instructions. Please note: Even if you will build it with VECSIM_MARCH=x86_x64-v4, the AVX512 instructions are not supported on your machines. The best-supported optimization (SSE/AVX/AVX512) is selected in runtime according to your machine specs.
   You can check for additional information here:

• https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html
• https://www.intel.com/content/www/us/en/products/sku/64596/intel-xeon-processor-e52690-20m-cache-2-90-ghz-8-00-gts-intel-qpi/specifications.html

Thank you for quick response.

Reinstalled GCC, updated links and priorities.
Almost there (: but:

Interesting thing: RediSearch, which build VecSim too during compilation, got compiled without any problems.

In general, Debian is a place you can't get a modern GCC installed except by building it (Ubuntu and CentOS systems have access to relatively modern gcc, hence readies/bin/getgcc --modern).
It is possible to build VecSim with gcc-10 no sweat. You can try it on Debian Bullseye or Ubuntu Focal, and deduce from there.
May I ask why do we insist on having it on Stretch?
Our containers, for instance, are aligned on Bullseye and we naturally opt for not building GCC ourselves.
Thank you.

@somsomers any updates on your side? did you manage to build?

[somsomers]

Had to build it in docker for now.
