Bug 616154 – sys-devel/gcc-6.4.0 does not install omp_lib.mod for 32 bit gfortran compilation in /usr/lib64/gcc/x86_64-pc-linux-gnu/6.3.0/32/finclude directory (eg lapack-reference problem)

• Status: RESOLVED OBSOLETE
• Product: Gentoo Linux

[Description milan hodoscek 2017-04-20 19:13:59 UTC]

gcc-6.3.0 doesn't install omp_lib.mod for 32 bit fortran (gfortran -m32 -fopenmp) compilation in /usr/lib64/gcc/x86_64-pc-linux-gnu/6.3.0/32/finclude directory.
This prevents to compile any fortran program that uses openmp. For example lapack-reference does not compile. I put a link from ../../finclude and everything compiles OK. Although .mod files are now binary I guess they are the same for -m32 as for -m64 compilations, so the whole directory could be just a link ??

Easy to reproduce the problem with these commands:
cat > omp.f90
  use omp_lib
  write(*,*)'works...'
end program
<Ctrl-D>

gfortran -m32 -fopenmp omp.f90

This is my emerge --info:

[Comment 1 Andreas K. Hüttel 2017-10-03 18:06:25 UTC]

Probably worth another look.

[Comment 2 Andreas K. Hüttel 2017-10-22 21:41:33 UTC]

This is also the case for 6.4.0.

However, it's not a regression compared with current stable, so it can't block stabilization.

[Comment 3 Sergei Trofimovich (RETIRED) 2020-02-02 20:43:35 UTC]

That is known upstream as https://gcc.gnu.org/PR60670

[Comment 4 Sergei Trofimovich (RETIRED) 2020-02-02 21:16:01 UTC]

Building gfrotran manually from head I see fincluse being installed correctly:

./lib/gcc/x86_64-pc-linux-gnu/10.0.1/finclude/omp_lib.mod
./lib/gcc/x86_64-pc-linux-gnu/10.0.1/finclude/omp_lib_kinds.mod
./lib/gcc/x86_64-pc-linux-gnu/10.0.1/32/finclude/omp_lib.mod
./lib/gcc/x86_64-pc-linux-gnu/10.0.1/32/finclude/omp_lib_kinds.mod

Let's see if it was fixed or toolchain.eclass mixes up things.

[Comment 5 Sergei Trofimovich (RETIRED) 2020-02-02 21:35:02 UTC]

9.2.0 branch also installs correct files:

./lib/gcc/x86_64-pc-linux-gnu/9.2.0/finclude/omp_lib.h
./lib/gcc/x86_64-pc-linux-gnu/9.2.0/finclude/omp_lib.f90
./lib/gcc/x86_64-pc-linux-gnu/9.2.0/finclude/omp_lib.mod

./lib/gcc/x86_64-pc-linux-gnu/9.2.0/32/finclude/omp_lib.f90
./lib/gcc/x86_64-pc-linux-gnu/9.2.0/32/finclude/omp_lib.mod
./lib/gcc/x86_64-pc-linux-gnu/9.2.0/32/finclude/omp_lib_kinds.mod

gcc-9_2_0 tag was installed as:

time { ../gcc/configure --disable-bootstrap --enable-languages=c,fortran --prefix="$(pwd)/../gcc-fortran-installed" && make -j9 && make install -j9; }

Looking at toolchain.eclass specifics.

[Comment 6 Sergei Trofimovich (RETIRED) 2020-02-03 00:08:20 UTC]

9.2.0 ebuild also installes needed files. 6.5.0 does not. Must have been fixed upstream somewhere in that range. Let's see if I can bisect it.

[Comment 7 Sergei Trofimovich (RETIRED) 2020-02-03 00:14:04 UTC]

7.5.0 ebuild installs correct files

[Comment 8 Sergei Trofimovich (RETIRED) 2020-02-03 09:51:50 UTC]

Let's close as obsolete. gcc-7.5+ should be fine here.
