As luck would have it, I just compiled F2c under V2 because I wanted to 
build the SPICE circuit simulator. I assume your DJGPP setup is correct 
(ie DJGPP variable points at your DJGPP.ENV file, etc), and you unpacked 
f2c95201.zip in your DJGPP directory (for me, /lang/djgpp).

I just unpacked the ZIP file the usual way (with -d). Next, change to your

 /djgpp/contrib/f2c95201/src/src

directory (or wherever you unpacked the files) and edit the Makefile, 
like this:

replace the line saying 

  cat gram.head gram.dcl gram.expr gram.exec gram.io >>gram

(this is line 37 of the makefile) with

  type gram.head >>gram
  type gram.dcl >>gram
  type gram.expr >>gram
  type gram.exec >>gram
  type gram.io >>gram


also replace the line saying
  
  rm -f gram gram_tab.c

(this is line 48 of the original makefile, but once you change line 37, 
it's going to change too) with

  del gram
  del gram_tab.c

An important caveat: do not use QEdit (damn that ^%$@#@#$!@ editor) for 
editing the makefile! it strips tabs from the file and replaces them with 
spaces, causing Make to whine endlessly. Use the DOS EDIT command, it 
works for me, because any command (like `del gram') must be tabbed once 
from the beginning of the line.

Once you have modified the makefile, change to the directory

 /djgpp/contrib/f2c95201/src

and execute the script `mk.bat'
If you're lucky, everything will compile correctly (at least, it did for 
me, and I've rebuilt everything while typing this mail to make sure I  
got it right !!!)

When the build is complete, execute the script `install.bat'

That's it! (but I don't know if f2c works OK, I just know it got built 
correctly)

FWIW: I built that stuff on an incredibly-buggy Pentium-100 with 16Meg of 
RAM (I mean incredibly buggy 'cause it can't run Windoze for 10 minutes 
without crashing -- some stupid hardware problem). But since DJGPP 
compiled everything correctly with no problems, you should be able, too.
  
BTW: I *don't* know how to use f2c, I just needed the libf2c.a file and 
f2c.h so that I could compile SPICE. I tried using the f2c binary on a 
Fortran file I found on Netlib, but it doesn't work !!! :(

Here's what I did:

f2c <pchfd.f
    pchfd:
Error on line 204: nondigit in statement label field ".    "
Compiler error line 38 of : do_format:  Unknown token type in 
intermediate file


Do you know what's going on here? the line 204 of pchfd.f contains only a 
single period. What's happening? not that I program in Fortran  8(

But I *did* get SPICE 2g6 to compile and execute correctly, so I must've 
gotten at least half right!

Cheers,

Orly
