Hi I am getting the following error messages when I attempt to run a fortran 95 test program. peterm@currawong ~]$ a.out a.out: error while loading shared libraries: libg2c.so.0: cannot open shared object file: No such file or directory The fortran compilation is apparently error less I have two installations of f95. One down the /opt tree and the other down the /usr/local tree. Both give the same error message. My .tcshrc file has the line set LD_LIBRARY_PATH = ( /usr/local/lib /opt/lib /usr/lib and the echo $LD_LIBRARY_PATH yields. [peterm@currawong ~]$ echo $LD_LIBRARY_PATH /usr/local/lib /opt/lib /usr/lib Sorry I cannot see my problem so appreciate comments. Thanks
