Re: [AMBER] installation error in AmberTools1.5

This means that the library necessary to link C and Fortran codes cannot be
found (libgfortran.a, This library _did_ exist for GCC
4.3 (which is the version of g++ you have), so something must be wrong with
your setup.

We need a little more information in order to help.

What version of Linux are you using? What does "gcc --version" and
"gfortran --version" return? How did you install your compilers?

All the best,
