Bug #: 52313 Summary: useless error message for old version of .mod file Classification: Unclassified Product: gcc Version: unknown Status: UNCONFIRMED Severity: enhancement Priority: P3 Component: fortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: daniel.pr...@monash.edu This is a fairly minor request, but should be an easy one to fix. When upgrading gfortran to a newer version, you often get the following error message: use blah 1 Fatal Error: Parse error when checking module version for file 'blah.mod' opened at (1) ...cryptically referring to the fact that the module was previously compiled with an old version of gfortran. Any chance this can be changed to something more understandable by humans? My suggestion is: "Fatal error: 'blah.mod' module version is wrong, most likely because it was compiled with an old version of gfortran. Delete the .mod file and retry." (this bug report is because I got a support request because some code I support didn't compile with a new version of gfortran) Thanks, Daniel
