My company recently took ownership of a project/website that was
utilizes Apache, mod_perl, and Apache::ePerl on a Linux box. While I'm
familiar with Apache, mod_perl, and other embedding methods (Embperl to
name one), I'm new to ePerl.
I don't have access to the original server, and I've been asked to build
a Linux/Apache/mod_perl/ePerl box from scratch. After a very basic
RedHat install (to avoid RPM dependancy hell), I successfully built Perl
5.6.1 and Apache 1.3.26 with mod_perl 1.27 and mod_ssl 2.8.10 all from
source tarballs. Unfortunately on my last step, I'm having trouble
building ePerl from the 2.2.14 or 2.2.13 tarballs.
I'm attempting to build the integrated Perl 5 modules (Parse::* and
Apache::ePerl, etc.). The first step, perl Makefile.PL works fine.
However, I get the following error when doing make:
[gregg@litlink eperl-2.2.14]$ perl Makefile.PL
Configuring for ePerl 2.2.14 (02-08-1998)
Now please type 'make' to compile. Good luck.
[gregg@litlink eperl-2.2.14]$ make

Latest Perl found on your system is ,
but at least Perl version 5.003 is required.
In case the newer one is not in PATH, just use
the option --with-perl=/path/to/bin/perl to
provide the correct executable.

I came to the conclusion that Perl 5.6.1 produces a different output
from its perl -v argument than version 5.003 for example. So I went
into the configure file, and I edited line 574 to read
'perlvers=5.6.1'. That didn't work, and produced a similar error to
the one described above, so I edited the line to read 'perlvers=5.003'.
This time, it began making the files, but it stoped with a compiler error:

I'm using gcc version 2.96 2731 (Red Hat Linux 7.3 2.96-110). While
I can hack Perl, I know little of C. I know ePerl-2.2.14 was released in
1998, so it wasn't written with version 5.6.1 of Perl or gcc 2.96 in
mind. Is there a way to build ePerl with a modern Linux distro? Am I
doing something wrong, or must I use an older version of Perl and/or gcc?
Many thanks,
Gregg Casillo
