I have Cygwin installed on my WIndows box. I am trying to install a program that requires gfortran to build. I found a few solutions mentioned previously such as apt-cyg gcc4-gfortran to install the fortran compiler. When I do this, with a working internet connection, I get the error message 'unable to locate package gcc4-gfortran'. If I leave off the gcc4- part, I get the same error message. While the previous solution worked 6 years ago for another user, it is not - apparently - working for me. Can anyone suggest a solution for this repetitive problem? Thanks
