Description Sam Steingold 2006-05-12 10:50:57 EDT
libgfortran 4.1.0 does not install /usr/lib/
on which some executables rely.
the user has to create a symlink:

cd /usr/lib
test -f || sudo ln -sv*.*

(there is no component named libgfortran in bugzilla, so I have to use gcc which
is the source of the Fortran 95 runtime)
Comment 1 Jakub Jelinek 2006-05-12 10:59:52 EDT
Programs which do that are incredibly broken. is included in gcc/gfortran specific directory, similarly
to other gcc provided libraries, as what exactly this points to is dependent
on the compiler version used (you need different libgfortran (
when using GCC 4.0.x, different when using 4.1.x ( and yet
different when using 4.2.x (
So, rather than using crappy checks for /usr/lib/ (after all,
on x86_64, ppc64, s390x etc. that wouldn't be in /usr/lib64 anyway) they should
use standard (e.g. autoconf) checks for presence of libraries.
Comment 2 Sam Steingold 2006-05-15 17:13:25 EDT
without the symbolic link /usr/lib/, "-lgfortran" does not work:
/usr/bin/ld: cannot find -lgfortran
collect2: ld returned 1 exit status

I am reopening the bug:
 how do I recompile my program so that it uses /usr/lib/

Comment 3 Jakub Jelinek 2006-05-15 17:21:23 EDT
When you forgot to install gcc-gfortran package, that's not really surprising.
If you install it, that command will work just fine.
Comment 4 Sam Steingold 2006-05-15 18:15:13 EDT
I have these packages:

(Alas, I am stuck with c++ software that want 3.2)
Comment 5 Jakub Jelinek 2006-05-16 03:04:01 EDT
If you are using compat-gcc-32, then you obviously can't mix that with gfortran,
you should use compat-gcc-32 with g77 (and it's -lg2c), or gcc 4.x with gfortran.
Please stop reopening this.
