Hi Matthias,
Thank you for replying quickly.
I typed the two commands in your email.
Here's what happened:
$ which g++
/usr/bin/g++
$ ls -l /usr/bin/g++
lrwxrwxrwx 1 root root 7 2009-03-22 10:49 /usr/bin/g++ -> g++-4.3
$ g++ --print-file-name libgfortran.so
/usr/lib/gcc/i486-linux-gnu/4.3.3/../../../../lib/libgfortran.so
Then I removed the symbolic link for
/usr/lib/libgfortran.so that fixed my problem, and
ran g++ again.
$ rm /usr/lib/libgfortran.so
$ g++ --print-file-name libgfortran.so
libgfortran.so
Does that help?
Thanks,
Kingsley
