Hello,
I'm trying to build a cross compiler for UEFI, and having difficulties
building libgcc after having built the compilers themselves. I've already
built a cross compiler and libgcc (with and without red-zone) for
freestanding x86_64-elf in the same machine, so not sure what the issue is.
The machine is an Arch vm, with the following packages installed through
pacman:
gcc-8.2.1+20180831-1
bison-3.0.5-1
flex-2.6.4-1
gmp-6.1.2-1
libmpc-1.1.0-1
mpfr-4.0.1-1
texinfo-6.5-1
>From the AUR, I got:
osl-0.9.2-2
isl-0.20-4
cloog-0.20.0-1
I'm using binutils 2.31 (compiled separately, binutils for
target x86_64-w64-mingw32 were built and installed fine to the same prefix
I'm trying to install my cross compiler to). For gcc, I'm using the branch
gcc-8-branch at revision 264489. I tried to use the 8.2.0 release, but I
ran into an issue with isl 0.20 having moved some headers around, causing
the build to fail. That was fixed in the branch with gcc 8.2.1.
The source for gcc was downloaded to ~/src/gcc. After that, I did:
export PREFIX="$HOME/opt/cross"
export TARGET=x86_64-w64-mingw32
export PATH="$PREFIX/bin:$PATH"
mkdir ~/src/gcc-build-$TARGET
cd ~/src/gcc-build-$TARGET
../gcc/configure --target=$TARGET --prefix="$PREFIX" --disable-nls
--enable-languages=c,c++ --without-headers
make all-gcc
This far, everything worked ok. Then I did:
make all-target-libgcc
And that's where I hit a wall. Make fails with the last few lines of output
being:
checking how to run the C preprocessor... /lib/cpp
configure: error: in
`/home/os/src/gcc-build-x86_64-w64-mingw32/x86_64-w64-mingw32/libgcc':
configure: error: C preprocessor "/lib/cpp"fails sanity check
See `config.log' for more details.
make: *** [Makefile:12659: configure-target-libgcc] Error 1
I won't copy the whole contents of the config log (unless someone feels
they'd be useful) but where it starts having issues it shows (log is at
x86_64-w64-mingw32/libgcc/config.log):

Anyway, been trying to toy with options and such, but no change in results.
Not sure what to make of this. I would appreciate any help anyone could
provide.
