Subject: Re: converting gcc from glibc to musl
since patching with the recommended patch (the one i had wasnt a full patch
apparently) i have been able to use this option --host=i686-linux-musl
however now when i compile i run into new issues.
Firstly gmp, mpfr, and mpc do not like this flag obviously since they do
not have the musl settings patched in so i cant compile with the musl
wrapper because i cannot include those math libraries and when i try to
prebuild them and use the flag --with-mpfr=/target/location it errors out
saying it cant find any compatible versions of these libs/headers.
that brings me to compiling without the musl wrapper but with
--host=i686-linux-musl and that does work until you try to run the binary
of gcc made static which gives the error cant execute or doesnt exist.
Checking with ldd shows its static so the binary itself is corrupted in
some way.
My question now becomes, what would be the troubleshooting steps to see how
its broke if possible?
