The semicolons prevented the "configure" script from seeing the variable settings because the shell would have made them into shell variables rather than environment variables (due to the semicolons). The following would have worked: CPPFLAGS='-Df2cFortran' CC=/usr/bin/gcc CFLAGS='-O \ -fno-builtin' PERL=/usr/bin/perl FC=g77 FFLAGS=-O \ ./configure Regards, Steve Emmerson Ticket Details =================== Ticket ID: GWR-559570 Department: Support UDUNITS Priority: Normal Status: Closed
