OK, here are the relevant lines from config.log: configure:17833: gfortran -g -O2 -c conftestf.f configure:17836: $? = 0 configure:17839: gfortran -o conftest -g -O2 conftestf.o conftest.o ld: warning: ignoring file conftest.o, file was built for unsupported file format ( 0xcf 0xfa 0xed 0xfe 0x 7 0x 0 0x 0 0x 1 0x 3 0x 0 0x 0 0x 0 0x 1 0x 0 0x 0 0x 0 ) which is not the architecture being linked (i386): conftest.o Undefined symbols for architecture i386: "_sub_", referenced from: _MAIN__ in conftestf.o ld: symbol(s) not found for architecture i386 Your gfortran is compiling for i386, a 32-bit architecture, but your gcc is apparently compiling for a different architecture, probably 64-bit x86_64. You have to use the same architecture if you want to link the software together. You could do this by either using the right flags for gcc, for example -m32 or maybe -arch i386, or use a flag for gfortran, maybe -m64 or -arch x86_64. If you installed netcdf-fortran from MacPorts, you may have a gfortran that produces 64-bit objects with a long name something like /opt/local/bin/x86_64-apple-darwin-gfortran-mp-4.7 but it might be easier to just use the gfortran you have and make gcc produce 32-bit objects. --Russ > On Mar 25, 2013, at 4:57 PM, Unidata netCDF Support <address@hidden> > wrote: > > >> Hi Russ, > >> > >> I don't have problem installing C library with --disable-netcdf-4.
