Unable to build boost-1.86.0 with gcc-4.8.5; std::align missing

[utoni]

I am getting the following build error:

gcc.compile.c++ bin.v2/libs/process/build/gcc-4.8/release/x86_64/cxxstd-11-iso/threading-multi/visibility-hidden/ext/env.o

   return std::align(alignment, size, ptr, space);
          ^

std::align seems to not be available on gcc-4.8.5 for whatever reason, but building boost-1.85.0 with the same CXX works without any issues. Any hints?

this is a known missing feature for gcc😂 see: https://stackoverflow.com/questions/27064791/stdalign-not-supported-by-g4-9

@utoni Is there a current Linux distribution still providing gcc-4.8.5? It appears that there is a package for Ubuntu 16.04 Xenial, for example.

Unfortunately, there are still companies out there, which are using CentOS 7..

(issue was fixed by compiling gcc-11)
