Very Computer

I just downloaded PGP262.  I was able to get it to compile under
Slackware 2.3, but not under Slackware 3.0.  It gave a couple of
screenfuls of errors really fast, before it bombed.  Is there
something inherently incompatible with the new GCC, or maybe a
simple fix?  

I can post the error messages here if that helps, but first I have to
remember how to direct them to a file (2&>1 or something).

Thanks in advance for your help

Ok, I got the bash man page to tell me how to save error messages.
Here are the messages I get when I try to compile PGP under
Slackware 3.0:

I am going to hazzard a guess that gcc isn't using some library.
If this is the case, how can I tell which one, and how can I
correct it?

Thanks in advance.

  There's a very simple fix for this problem.  I applied the fix and
compiled it with no problems whatsoever.

Here's the relevent snippit from the document:

New Improvements

Linux/ELF changes

THe PGP 2.6.2 sources do not build under Linux/ELF. If you want to build
2.6.2 as an ELF binary, you need to make two changes, one each to 80386.S
and zmatch.S. Near the beginning of the file you will find a #if
directive for SYSV. Apply the appropriate change to the appropriate file
to get it to work 13 Oct 95:

   #ifndef SYSV ==> #if !defined(SYSV) && !defined(__ELF__)

   #ifdef SYSV ==> #if defined(SYSV) || defined(__ELF__)

linux:

        CFLAGS="$(RSAINCDIR) -O6 -g3 -DUNIX -DIDEA32 -DASM" \
        ASMDEF=-DSYSV

and recompile, it _should_ work then.

Why did the mathematician name his dog Cauchy?
Because he left residue at every pole.

Thanks go to several people who responded privately with solutions.
For any one else with this problem, the easiest solution I received
is to add the following to the end of the linux entry in the makefile:

 ASMDEF=-DSYSV
