Hi Manfred,

Thanks for your reply. I have made the changes that you suggested to
my /etc/bashrc file but I still get the same error when I try to compile
hello.f90.

That file is simply:
       program hello
          print *, "Hello World!"
       end program hello

When I compile that code I get the following.

Documents]$ gfortran hello.f90 -o hello.exe
/usr/local/gcc-4.8/libexec/gcc/x86_64-unknown-linux-gnu/4.8.2/f951:
error while loading shared libraries: libcloog-isl.so.4: cannot open
shared object file: No such file or directory


Could the previous version of g compilers be conflicting with this
latest version? I did not remove the previous version whilst trying 4.8
out in /usr/local. The files for the older version are in /usr/ but I
know that I am running the newer version by using the gfortran -v
command.

Documents]$ gfortran -v
Using built-in specs.
COLLECT_GCC=/usr/local/gcc-4.8/bin/gfortran

--prefix=/usr/local/gcc-4.8
Thread model: posix
gcc version 4.8.2 20130704 (prerelease) (GCC) 

The error message given during compiling hello.f90 talks about
libcloog-isl.so.4 and in the information provided by that gfortran -v it
says:
--with-cloog-include=/usr/include-cloog
--with-cloog-lib=/usr/lib64
DOes this mean that gfortran is looking for libclood-isl.so.4 in these
folders? These are not the folders that I have placed libclood-isl.so.4.
How can I get gfortran to use the correct folder for this file?

Or is there another issue?

Thanks for your help,
Jonathan
