Hi SK, On our RHEL5 system we have: /usr/lib64/libgfortran.so.1 which is provided by package libgfortran-4.1.2-52.el5.x86_64 /usr/lib64/libgfortran.so.3 which is provided by package libgfortran44-4.4.6-3.el5.1.x86_64 Both packages installed and up to date. I can't find a package called compat-libgfortran-41. Thanks, Matthew ________________________________________ From: Shakthi Kannan [shakthimaan@xxxxxxxxx] Sent: Wednesday, March 14, 2012 6:11 PM To: Matthew Hobbs Cc: gcc-help@xxxxxxxxxxx Subject: Re: external BLAS library with gfortran 4.1 or 4.4 on rhel5 Hi Matthew: --- On Wed, Mar 14, 2012 at 12:13 PM, Matthew Hobbs <matthew.hobbs@xxxxxxxxxxxxx> wrote: | gfortran44 -L/usr/lib64/atlas -fexternal-blas -lf77blas matmultest.f90 -o matmultest_f77blas | /usr/bin/ld: warning: libgfortran.so.1, needed by /usr/lib64/atlas/libf77blas.so | may conflict with libgfortran.so.3 \-- Could you try installing and using the compat-libgfortran-41 package that provides libgfortran.so.1?
