The Linux and Windows versions of Gfortran work with gfortran -static -o prog.exe prog.f to produce an executable that can be run on other systems where gfortran is not installed. But the -static option does not seem to work with gfortran on a MAC, I get ld: library not found for -lcrt0.o and another person with a different version of gfortran on his MAC gets the same results. gfortran -static-libgfortran prog.f works, but the executable does not even seem to run on other systems with a different version of gfortran. So it seems to be impossible to produce any executable with gfortran that has the dynamic libraries loaded so it can run elsewhere. Is there a way to get -static to work on MACs, or any other way to produce a portable executable? Thanks for your help Granville Sewell
