Pieter, Thank you for your Email about going to http://g95.sourceforge.net to find out more information about the Gnu Fortran 95 g95 project. I am a big user of the gnu g77 Fortran compiler. It optimizes better than the gcc (in my opinion), and the benchmark tests on the web which compare the Gnu g77 Version 3.2 compiler versus the expensive Fortran compilers like Digital Fortran and Intel Fortran reveal that with all compilers set to maximum optimization, there is little difference between them. I've used g77 with maximum optimization to compile a 1 million line Fortran Linear Algebra library called Lapack. The generated EXE file passed the rigorous tests successfully. I feel that g77 is a very high quality optimizing Fortran 77 compiler. Do you use the gnu g77 Fortran compiler now? - Bill On Fri, 27 Dec 2002 12:59:11 +0100 Pieter Thysebaert <pie...@in...> writes: > On Thursday 26 December 2002 22:58, William G Sternbach wrote: > > Hello, > > > > I know most of the people on this list use gcc 3.2 as a "C/C++" > compiler. > > I also use the FORTRAN 77 "g77 compiler" which is included with > Mingw > > Gcc version 3.2. > > This FORTRAN 77 g77 compiler can only compile FORTRAN programs > written in > > the 1977 ANSI Standard FORTRAN Language. > > The Gnu G77 FORTRAN compiler is heavily used in the scientific and > > mathematics > > community (especially on Linux). > > > > I want to compile some FORTRAN source code which is written in the > newer > > FORTRAN 90/95 > > language (which is based on the 1990/1995 ANSI standard FORTRAN). > > > > 1) Does anyone know if there are plans to upgrade this Gnu > FORTRAN 77 > > compiler > > so it can compile programs written in the FORTRAN 1990/1995 > ANSI > > standard. > > There's some info at http://g95.sourceforge.net > > Pieter > > ________________________________________________________________ Sign Up for Juno Platinum Internet Access Today Only $9.95 per month!

Sorry, I don't even know FORTRAN to be honest; I just stumbled on the g95 sourceforge site once ;-) Pieter |
