[Bug other/78424] New: intl reincludes sysroot into searching for ld
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78424 Bug ID: 78424 Summary: intl reincludes sysroot into searching for ld Product: gcc Version: 7.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: other Assignee: unassigned at gcc dot gnu.org Reporter: neotheuser at ymail dot com Target Milestone: --- Created attachment 40085 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=40085&action=edit intl duplicated directory error Hello! I have switched to GLIBC and the GMP issue is gone, but now when GCC builds, it searches for sysroot/usr/lib/libc.so.6 inside sysroot/git-toolchain-bin. It should be an absolute path, which is simply just sysroot/usr/lib/libc.so.6. "/home//git-toolchain-bin/usr/x86_64-pc-linux-gnu/bin/ld: cannot find /home//git-toolchain-bin/usr/lib/libc.so.6 inside /home//git-toolchain-bin" ~/git-toolchain-bin/usr/lib/libc.so.6 exists, but there is no /home//git-toolchain-bin/home//git-toolchain-bin/usr/lib/libc.so.6 as that would be silly. Configure line is as follows: mkdir build && cd build && ../configure --prefix=/home//git-toolchain-bin/usr --with-local-prefix=/home//git-toolchain-bin/usr --with-sysroot=/home//git-toolchain-bin --disable-nls --disable-shared --disable-multilib --disable-libatomic --disable-libgomp --disable-libmpx --disable-libquadmath --disable-libssp --disable-libvtv --disable-libstdcxx --enable-languages=c,c++ --disable-lto --with-system-zlib --disable-werror --disable-gold --without-isl --disable-libcilkrts --disable-libitm --disable-libsanitizer Removing or keeping --with-local-prefix has no effect. I initially started with having --with-native-system-header-dir set to sysroot-dir/include but having --with-sysroot=sysroot-dir set along with it caused redundancies, so I dropped --with-native-system-header-dir. --with-build-sysroot caused issues finding stdio.h (which was present in the directory that --with-native-system-header-dir was set to, not too sure what happened there, just changed configure options) so changing it to simply --with-sysroot got me a little further. Build log attached.

relocation X against symbol `Y can not be used...
I still have this problem, just ran git pull on master branch, this is my
configure line:
$ cd gcc && mkdir build && cd build
$ ../configure --prefix=/home//git-toolchain-bin/usr
--with-local-prefix=/home//git-toolchain-bin/usr
--with-native-system-header-dir=/home//git-toolchain-bin/usr/include
--disable-nls --disable-shared --disable-multilib --disable-libatomic
--disable-libgomp --disable-libmpx --disable-libquadmath --disable-libssp
--disable-libvtv --disable-libstdcxx-pch --enable-languages=c,c++
--disable-werror --without-isl --disable-libcilkrts --disable-libitm
--disable-libsanitizer --disable-lto --disable-gold
Replacing --disable-libstdcxx-pch with --disable-libstdcxx brings me this:
xg++: error: unrecognized command line option '-funconfigured-libstdc++-v3'
Adding/removing c++ from enabled languages seems to have no effect. Recompiling
Binutils (2.27 branch) with CFLAGS="-O2 -fPIC" and CXXFLAGS="${CFLAGS}" added
to configure line did not fix the issue (nor change it in any way) and
compiling GCC with that same option causes it to die much earlier.
This is as far as I've got so far trying to build a toolchain sysroot, very
close!
