The ROPP /m4/cm_compiler_defualts.m4 detects 'GNU' fortran and sets the default to the f2c form. This is correct for g95, but not (now) for gfc. Adding -DNAGf90Fortran to the configure CPPFLAGS doesn't override the default - both appear in Makefile, so presumably gcc only accespts the first occurance (the default). While ropp_tools appears to build correctly with gfc, the print_stdout.c & print_stderr.c in messages/ are not built with the right interface; this causes dependent modules (ropp_io) to fail ./configure, as the test for 'message' in ropp_tools fails to comple. Hand-editing ropp_tools/build/Makefile to change AM_CPPFLAGS from 'f2c' to 'NAGf90' allows the correct C interfaces in ropp_tools to be built, and ropp_io ./configure works again with gfc. cm_compiler_defaults.m4 (and/or the vendor detector code in cm_compilers.m4) needs modifying to detect gfc from g95 (both report as 'GNU').
