Fortran 90 compilers for the PC
 *******************************
 (Thanks a lot to Clive Page for various information on PC compilers)

 This list was prepared on January 1997, and was partly updated 
 on March 1997, and December 1997, and May 1998


 O  FREE COMPILERS:

    o  Clive Page from Leicester U. kindly offers a tested 
       package of GNU g77 (Fortran 77 + some Fortran 90 
       enhancements) ready to use on a PC, and suitable for 
       DOS and Windows: 

        Intro doc (12.5 KB) 
        Zipped exe (1.31 MB) 
        Zipped doc (0.36 MB) 

       The files are under 1.44 MB each for convenience.  

       A North American mirror site of Clive's package,
       which is easier to get, especially for people in 
       North America, and maybe anywhere outside Europe:

        USA mirror 

       Two other sites offering a similar package (Thanks
       to Clive for the URLs!):

        Cygnus 
        Block 5564 


    o  Lahey Computer Systems offers a subset version 
       of its flagship Fortran 90 compiler (LF90).  
       The subset compiler is called ELF90, comes with 
       minimal documentation, and is ready to use in a 
       Windows environment.  
       The subset compiler doesn't contain many "dusty" 
       Fortran 77 features (e.g. common blocks, storage 
       association), all of them replaceable by better 
       Fortran 90 features:

        The ELF page 

       There are good reports on Lahey products.

    o  Imagine1 offers the "F programming language", 
       another rational subset of Fortran 90.
       The version for the Linux PC operating system
       (not including documentation) is free. 
       F is supposed be the true stepping stone 
       to HPF and at the same time replace Basic, 
       Pascal and C for teaching purposes: 

        F for Linux (1 MB) 

       There are trial versions for other platforms, 
       they are also free, but the program size is
       limited. 

        F free/trial compilers (1 MB)

***    Imagine1 F - educational subset (free for Linux!)
          (dusty features removed, for inexpensive F90 learning)
          Imagine1 Inc offers F, the subset language for Unix and 
          Windows that they hope will be the true stepping stone 
          to HPF and at the same time replace Basic, Pascal and C 
          for teaching purposes. The version for Linux is FREE. 

          The F compiler is suitable only if one is using pure F90 
          syntax with none of the older obsolescent F77 features.  
          The price is good - free under certain circumstances!

***    Lahey LF90 
          for:  DOS, Windows including Pentium optimizations and 
                Interacter Kit.
          Lahey has a native LF90 compiler for Windows and DOS 
          Version 3.0 provides an integrated Windows development 
          environment. 

          Lahey has been shipping a native LF90 compiler for DOS 
          since 29 August, 1994. It is particularly well optimized 
          on the Pentium.

          (very fast compilation; excellent reputation for support)
          Good code generation, good diagnostics, fast compilation, 
          and good support are often quoted as reasons why folks 
          liked LCS.

          very cheap. In fact, the elf90 compiler itself can 
          be downloaded free from the Web site.

          The ELF compiler is suitable only if one is using pure F90 
          syntax with none of the older obsolescent F77 features.  

          There are good reports on Lahey products.

          "Do not consider the PC compiler from N.A.Software, when I 
          tried it out last year it was by no means good enough for 
          serious use."

***    Salford FTN90 
          Salford Software markets a PC version of the NAG f90 compiler, 
          direct generation of object code. Also for Windows 95 and NT. 
          A very cheap student version is available.

          "I use the Salford FTN90 at home, and find that it is 
          pretty good: very few bugs or problems, fast compilation, 
          efficient code, and the company seems responsive to 
          questions/problem reports.  There is a special student
          licence, but be warned that you cannot save an .EXE file 
          with this system, you have to recompile each time.  
          This may be ok for class use, but probably not otherwise 
          (even though the compile speed is good).  Salford also 
          give you a library Clearwin+ which allows you to generate 
          good Windows applications - all the usual widgets."
