I am long-time embperl user.
Recently I've upgraded from ubuntu 13.04 to ubuntu 13.10., and embperl
has stopped working. cannot enable zembperl.* files in mods-enabled



The ubuntu installer has upgraded apache 2.2 to apache 2.4.
The upgrade worked, mod_perl works, but I suspect the upgrade broke the
embperl installation. It took me a while to realize that this happened.


Although Ubuntu 13.10 contains an embperl package in the standard repos,
I suspect it has been compiled for apache 2.2

HIer is some infor
Embedded Perl version v5.14.2 for Apache process 53123,
running since Sun Nov 10 18:38:00 2013

What can I do now?

Knut

Hi,

you can try the lastest version from the svn, but this is also not tested against Apache 2.4

On the mailing list there were some patches to get Embperl working with Apache 2.4.

I will integrate these patches in Embperl and make a new release, as soon as I have a little spare time

Gerald
