Bug ID: 104856
Summary: Build gcc with a target not containing '-gnu' gets
added to gnat target
Product: gcc
Version: 11.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ada
Assignee: unassigned at gcc dot gnu.org
Reporter: bib_aab at hotmail dot com
Target Milestone: ---
Building the gcc suite with Ada with a target such as x86_64-suse-linux causes
Target_Name to be set to x86_64-suse-linux-gnu in s-oscons.ads.
Build gcc with:
../configure --prefix=/opt/gcc-11 --infodir=/opt/gcc-11/share/info
--mandir=/opt/gcc-11/share/man --libdir=/opt/gcc-11/usr/lib64
--libexecdir=/opt/gcc-11/usr/lib64
--enable-languages=c,c++,objc,fortran,obj-c++,ada,go,d
--enable-offload-targets=nvptx-none, --without-cuda-driver
--enable-checking=release --disable-werror
--with-gxx-include-dir=/opt/gcc-11/include/c++/11 --enable-ssp --disable-libssp
--disable-libvtv --enable-cet=auto --disable-libcc1 --disable-plugin
--with-bugurl=https://bugs.opensuse.org/ --with-pkgversion='SUSE Linux'
--with-slibdir=/opt/gcc-11/lib64 --with-system-zlib
--enable-libstdcxx-allocator=new --disable-libstdcxx-pch --enable-libphobos
--enable-version-specific-runtime-libs --with-gcc-major-version-only
--enable-linker-build-id --enable-linux-futex --enable-gnu-indirect-function
--program-suffix=-11 --without-system-libunwind --enable-multilib
--with-tune=generic --build=x86_64-suse-linux --host=x86_64-suse-linux
Running 'gcc -dumpmachine' returns x86_64-suse-linux. This is as per the
configure switches, so all well and good.
However:
eth5:~$ grep Target_Name
/opt/gcc-11/usr/lib64/gcc/x86_64-suse-linux/11/adainclude/s-oscons.ads
Target_Name : constant String := "x86_64-suse-linux-gnu";
For some reason -gnu has been added. This means it is near impossible to build
the gprbuild tools since it compares them and barfs because they are not the
same. And we cannot just edit that file, since it states 'make changes to
s-oscons-tmplt.c and rebuild the GNAT runtime library.'
Why on earth is it adding -gnu? If it's a good idea, why doesn't -dumpmachine
also return it?
