If anyone knows of such a > beast, please let me know... This is something I keep around for the periodic requests for Fortran to C converters. I have not used any of the products. Also, "Dr. Dobbs Journal on Software Tools" usually carry advertisements from companies offering language converters. -gisle h. ============================================================================== From: dig@peritek.UUCP (Dave Gotwisner) Newsgroups: comp.lang.c,comp.lang.fortran Subject: Re: fortran to C converter Summary: Green Hills Software has one.

Cobalt Blue, a company out of San Jose has 2 FORTRAN-to-C translator products, FOR_C and FOR_C++. I have a copy of FOR_C and have seen demos of FOR_C++. If you need to deal with complex variables, then take a look at FOR_C++. The translation results in very readable code. FOR_C also handles complex but the resulting code might be best described as spaghetti, although it does a very nice job on other standard and non-standard FORTRAN.

Ask and ye shall receive..... Source for f2c, a Fortran 77 to C translator jointly developed by folks from Bell Labs, Bellcore, and Carnegie Mellon, is now freely available. F2c was derived from the original UNIX operating system's f77(1), and the generated C follows f77's calling conventions; on some machines, the resulting object files are interchangeable with (and behave indistinguishably from) objects compiled by f77. The main "advantage" of f2c is that it converts ANSI standard Fortran 77 into C without manual intervention, at least when invoked by a suitable script or makefile (that may need to exercise an f2c option to ensure that COMMON blocks are defined just once). The main "problems" are that f2c does no code restructuring (e.g., gotos are preserved) and that Fortran I/O gets converted into a bunch of calls; thus the translated C code doesn't look too pretty, and in general one would need to maintain the Fortran rather than its translation into C. [F2c is not meant to displace the services of commercial vendors whose business is to convert Fortran into maintainable C.] There is a plethora of options, many of which exist to support different compilation environments for the translated C (e.g., ANSI C or C++ compatability, different type sizes, separate files for COMMON blocks to appease "smart" linkers). So far f2c (and f2c-generated source) has compiled successfully on many machines: Sun, Vax, IBMRT, Apollo, SGI, MIPS, and Cray to name a few. F2c has been under test by the net community for over six months, and has been verified on the NBS tests, several large math libraries, floating point tests, even code for laying cable on the ocean floor! To find about f2c, send the following E-mail message to netlib (netlib@research.att.com or research!netlib): echo send index from f2c | mail netlib@research.att.com Your message will be answered automatically (by a program -- see CACM vol. 30 #5 (May, 1987), pp. 403-407). You will receive a reply explaining how to automatically acquire f2c source (about 600K), f2c library source (130K), and supporting info (man page, etc). ****************************** DISCLAIMER ****************************** Careful!

I first posted this to comp.lang.fortran and then later realized I might find some people here familiar with FORTRIX-C. If you have any $.02 about that fortran to c conversion product, I would love to hear from you. (Email prefered or followup to comp.lang.fortran, thanks!) *** DUCK. It's another post about fortran to c convertors! **** Actually, it isn't quite that general. Don't bother telling me about f2c; I read about it earlier in this group and will be chasing it down shortly. However, I have been requested (by my employer) to elicit opinions, recommendations, and/or warnings from anyone out there who has used the _FORTRIX-C_ conversion program for Unix (and specifically Sun workstations) by Rapitech Systems, Inc. Some of our specific concerns include compatibility with F77 on Unix, and ability to efficiently handle floating point formats (which I suspect will just be: don't do anything that keeps us from using -68881 and similar floating point optimization switches.) E-mail replies. If anyone expresses an interest I will post a summary in a week or two. Thanks! Mitch Mitchell S.
