[srslte-users] srsran installation fails on ubuntu 20.04

[Cristian Balint]

Hi Nadav,

 Your GCC (9.3.0) is old, it fails on the invoked "native" optimization for
"tikerlake" on your gen. 11 (latest) Intel CPU.
 To be able to compile it out of the box you should use the latest GCC 11
series of GNU compilers.

(*) As alternate option, you can try replace "native" string into "generic"
here:

https://github.com/srsran/srsRAN/blob/89f16eed2b7f2e6c45e675298f5829c230698e1d/CMakeLists.txt#L110
    Or use other appropriate GCC flags (as -march=):
https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html

(*) Make sure you invoke the -DHAVE_SSE, DHAVE_AVX, -DHAVE_AVX2 flags for
cmake as of arch is not detected (e.x. you set "generic").
