Dear Tim
thank you for your message. My sincere apologies for not being careful
enough in my descriptions.
I am all too aware of the frustrations and wasted time that these lapses
of care and exactness cause. Please let me try again in greater detail.
Okay I run on a Red Hat Fedora 8 system running on an 2800+ AMD 32 bit
processor. My standard shell is tcsh.
I have the following modules installed.
1. f95 which came as part of the Fedora distro. This is the ONLY
fortran compiler that currently works on my system. It is based on GNU
4.1.2
[peterm@currawong ~]$ which f95
/usr/bin/f95
Unfortunately this compiler will not support the GAMIT GPS code. The
main reason for this is the intrinsic functions including fseek. I did
try to install a test 4.3 in early December hoping to bypass some
problems but I never got a working 4.3 up.
2. g77 which is GNU 3.4.6 based. This compiler will support GAMIT up to
10.30. It needs user intervention for the maximum number of logical
units. I now report the same problem with this compiler that I have with
the GNU 4.2 compilers. Before December 2007, when I ran a Fedora 7
system this compiler was operational.
Here are the three command sequences that show the installation and run
attempt of g77
[peterm@currawong ~]$ which g77
/usr/local/bin/g77
[root@currawong /]
# find . -name libg2c.so -print
../usr/local/lib/libg2c.so
../usr/local/gcc-3.4.6/i686-pc-linux-gnu/libf2c/.libs/libg2c.so
[peterm@currawong ~]$ g77 testg77.f
[peterm@currawong ~]$ a.out
a.out: error while loading shared libraries: libg2c.so.0: cannot open
shared object file: No such file or directory
3. gfortran which is based on GNU 4.2.2. This compiler was working on my
Fedora 7 system. I had an important task for all of December so the
system work kind of got pushed to the side immediately after putting up
Fedora 8.
I have installations in my /opt branch and my /usr/local branch. I
point to the /opt branch.
[peterm@currawong ~]$ which gfortran
/opt/bin/gfortran
Then
[root@currawong /]# find . -name "libgfortran*" -print
../media/Fedora 8 i386 DVD/Packages/libgfortran-4.1.2-33.i386.rpm
../media/Fedora 8 i386 DVD/repoview/libgfortran.html

../opt/lib/libgfortran.a
../usr/lib/libgfortran.so.1.0.0
../usr/lib/libgfortran.so.1
but
[peterm@currawong ~]$ gfortran testgfortran.f
[peterm@currawong ~]$ a.out
a.out: error while loading shared libraries: libgfortran.so.2: cannot
open shared object file: No such file or directory
So it appears that it cannot find the libraries either.
The output from
[peterm@currawong ~]$ echo $LD_LIBRARY_PATH
/usr/local/lib /opt/lib /usr/lib
I trust that this is a better description of my problems.
I know that my colleagues at MIT who are on a Fedora 6 system have none
of the problems that I am now experiencing. They are unable to help at
this instant.
