Hi everyone, I am kind of new to cross-compiling (if we can call my task like this), so maybe my question is kind of stupid. I need to build my project for old runtimes (libstdc++, libgcc_s, etc) that came with GCC 6, but I can build my sourcecode only with newest C++ features, so I chose GCC 12 for this. Of course my API is old enough to support GCC 6. And of course I am aware of potential risks (like some implementations that can be missing in the old runtime). Currently I am doing this in a very hacky way, and build my project in a container that looks like this: https://gist.github.com/olologin/b4ba2db91fc5c526d625715b39ac4579 As you can see, starting from line 73 it gets hacky because I could not find a better way to make sure GCC 12 links my code with GCC 6 runtime instead of GCC 12. So I decided that I should just get rid of all *.so, *.a and *.o files in GCC12 install directory, and later when I build my project I point GCC12 on GCC6 runtime with -Wl,-L. Is there a better way to do this? Maybe I am missing something. Thanks in advance.
