Some gfortran options allow you to include paths to libraries and Fortran modules:
$ gfortran -c <código fonte> [opções]
Among the functions is the -J<path file .mod>, which allows to indicate the modules' directories, as well as -I and the -L.
The question is whether gfortran is possible to make use of environment variables and so define a path for the implementation of the programmes. Reference would also have been made to file.[90 or 95 or 03 or 08]?
