using gcc version 4.3.0 20070315 (experimental) The -fcase options are not in gfortran as they were in g77. Specifically -fcase-preserve. This makes it very hard to link to pre-compiled C libraries that have mixed case function names.
compile line and error message C:\sha>gfortran -c sha.f90 -fcase-preserve f951.exe: error: unrecognized command line option "-fcase-preserve" There is mention of -fcase-lower in the gfortran .pdf manual but it doesn't exist either. The addition of this g77 option to gfortran would be appreciated. Or a workaround / new method for mixed case functions calls from gfortran to C. -- Summary: gfortran is missing -fcase-preserve option Product: gcc Version: 4.3.0 Status: UNCONFIRMED Severity: minor Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: mralanmorgan at gmail dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31310
