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?

That's not what you're doing though since you do not pass --target, so try
adding --target=x86_64-suse-linux to the configure line.

--target defaults to --host when not given (and --host defaults to --build when
not given). Looks like something is using the canonical target name instead of
the target alias.

--- Comment #3 from Bib <bib_aab at hotmail dot com> ---
I tried rebuilding with:
../configure --prefix=/opt/gcc11a --enable-languages=c,c++,ada
--enable-offload-targets=nvptx-none, --without-cuda-driver
--enable-checking=release --disable-werror --enable-ssp --disable-libssp
--disable-libvtv --disable-libcc1 --disable-plugin
--with-bugurl=https://bugs.opensuse.org/ --with-pkgversion='SUSE Linux'
--with-system-zlib --enable-libstdcxx-allocator=new --disable-libstdcxx-pch
--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 --with-tune=generic
--build=x86_64-suse-linux --host=x86_64-suse-linux --target=x86_64-suse-linux
--disable-multilib
And it still happens:
big-iron:/home/src/build/gcc-11.2.0/build$ find /opt/gcc11a/ -name s-oscons.ads
-exec grep -Hi Target_Name {} \;
/opt/gcc11a/lib64/gcc/x86_64-suse-linux/11/adainclude/s-oscons.ads:
Target_Name : constant String := "x86_64-suse-linux-gnu";

--- Comment #4 from Bib <bib_aab at hotmail dot com> ---
I have a bug raised with Suse:
https://bugzilla.suse.com/show_bug.cgi?id=1196861
And they are saying:
Hmpf, so the directory name and the -dumpmachine output is using the configured
target, while s-oscons.ads contains the canonicalized variant. Gah!
Quick grepping on our binary packages indicates that that's the _only_ place
where
the canonical name is used, so maybe the best course of action would be to hack
on it long enough that the generated s-oscons.ads also just contains the
provided
name without canonicalization.
