gfortran: error trying to exec 'f951': execvp: No such file or directory

Question

I'm trying to compile a code found on the internet. Actually I'm trying to compile the code found at http://www.cs.berkeley.edu/~fowlkes/BSE/.

I tried to install gfortran and all the other libraries that are needed for compiling it in my MAC. But when I run the command make I get the following error:

$ make
(cd trlan && make -f Makefile.gcc)
gfortran -O3 -ffixed-line-length-132 -c dsort2.f
gfortran: error trying to exec 'f951': execvp: No such file or directory
make[1]: *** [dsort2.o] Error 1
make: *** [trlan/libtrlan.a] Error 2

I believed that the error is related to the version of my c++ compiler, that is not compatible with gfortran.

When I run the command gcc --version:

$ gcc --version
i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)

And when I run the command gfortran --version:

$ gfortran --version
GNU Fortran (GCC) 4.8.0 20120930 (experimental)

The Makefile under the directory that I'm running the command make is here: https://www.dropbox.com/s/q7mxvhnqg62ioum/Makefile.gcc

The Makefile under the directory trlan is here: https://www.dropbox.com/s/jydwpkg3f1upbgf/Makefile.gcc

Anyone has an idea of how to solve this problem or how to find tools that can help me solve it?

Try the steps in the comment 3. It might help. gcc.gnu.org/bugzilla/show_bug.cgi?id=33814 — user1810733

The simplest solution I found (perhaps not cleanest), is to statically link f951 in the path to the binary of gfortran:

find /usr/local/ -name f951

which for me returned:

/usr/local/gfortran/libexec/gcc/x86_64-apple-darwin11/4.6.2/f951
/usr/local/gfortran/libexec/gcc/x86_64-apple-darwin14/5.1.0/f951

so I put a link to the one that fits my system most closely in /usr/local/bin:

sudo ln -s /usr/local/gfortran/libexec/gcc/x86_64-apple-darwin14/5.1.0/f951 /usr/local/bin/.

And now gfortran works again. No need to uninstall XCode or any other exaggerated workload.
