Set your environment variable FC to null, and try again. (Do a "make distclean" first). In sh, I can do it like this: make distclean && FC= ./configure && make check If you want the fortran interface, I would suggest getting the latest version of gcc. There have been a lot of changes in gfortran in the last few versions of gcc, so hopefully upgrading to the latest version of gfortran will fix your problem, which I have never seen before!
