Darin, The only differences that I can see between your files and those that are known to work on a Linux platform have to do with the use of `integer*4'. Are you certain that your FORTRAN `integer*4' maps to your C `int'? Alternatively, do you have access to a true FORTRAN compiler, rather than the FORTRAN-to-C translator? In any case, would you please do the following: 1. Go to the top-level source directory. 2. Remove the file config.cache. 3. Execute the configure script. Trap the output and send it to me. -------- Steve Emmerson <address@hidden>
