Hi all,

Is anyone familiar with this error? This is on Apache 2.4. Please see
details below.

Cannot load modules/Embperl.so into server: /etc/httpd/modules/Embperl.so:
undefined symbol: PL_thr_key

Is there a change in how I would compile Embperl on Apache 2.4??

Thanks,
Jim

fyi, I found previous thread on this problem; it seems this was fixed in
2.5.0_3

After I installed mod_perl from source, I was able to make embperl 2.5.0_4

https://perl.apache.org/docs/2.0/user/install/install.html#Downloading_the_mod_perl_Source

[root@centos-s-2vcpu-4gb-sfo2-01 Embperl-2.5.0_4]# perl Makefile.PL

Found mod_perl 2.0 <<< I think you want to see this

Build with support for Apache mod_perl?(y/n) [y]
