Building toolchain under Win10 WSL - Missing gmp, mpfr and mpc

[marcopoloFR]

They are easy to install with ./sources/gcc-13.2.0/contrib/download_prerequisites
but you need to delete these options in linux-build-toolchain.sh
--with-gmp=/usr/local --with-mpfr=/usr/local --with-mpc=/usr/local

PS:
I'd love to have a GDB stub for debugging

I suppose I was working on the assumption that the user would figure out how to identify and install the missing dependencies.

But if you have an example of how this could be integrated into the install script, perhaps you could submit a pull request with those changes and I'll merge it in.

Thanks! :)

OK, I'll do it.

Sorry, no time to learn Git this morning.
I propose replacing line 49 in linux-build-toolchain.sh with :

if [ -e /proc/sys/fs/binfmt_misc/WSLInterop ];
then
echo "Windows Subsystem for Linux (WSL)"
(cd toolchain/sources/$GCC && contrib/download_prerequisites) || exit 1
(cd toolchain/build/gcc && ../../sources/$GCC/configure --target=$TARGET --disable-werror --prefix=$PREFIX-$GCCVER --enable-languages=c && make -j $CORES all-gcc all-target-libgcc && make install-gcc install-target-libgcc) || exit 1
else
(cd toolchain/build/gcc && ../../sources/$GCC/configure --target=$TARGET --disable-werror --prefix=$PREFIX-$GCCVER --enable-languages=c --with-gmp=/usr/local --with-mpfr=/usr/local --with-mpc=/usr/local && make -j $CORES all-gcc all-target-libgcc && make install-gcc install-target-libgcc) || exit 1
fi

Thanks. I'll give this a try.
