Hi I hope this is the correct place for this question and if not maybe you could point me to where I might find more help. I’d like the use the F95 compiler via cygwin (on Windows Vista). I’ve installed it as per instructions on this page: http://gcc.gnu.org/wiki/GFortranBinariesCygwin?action=fullsearch&context=180&value=cygwin&titlesearch=Titles when I type:> gfc –version I get a Microsoft pop up error box saying "gfortran.exe. has stopped working. A problem caused the program to stop working. Windows will close the program." Any idea on how I can sort this out? Thanks Alison
