Re: [mod_perl2]: Install error with M akefile.PL - uninitialized value at TestRun.pm

 

Ok. I finally got it to glue together with apache 2.2.22, perl
5.14.2, and mod_perl 2.0.7. The perl can probably be upgraded to newest.


However, mod_perl 2.0.7 will NOT do a static build (as daniel states
below, tho that looks real good otherwise) with large file support
enabled and no perl thread support enabled. It throws constant errors in
various places -> error: unknown type name 'off64_t'. 

So it appears it
has to be built as a dso under those circumstances, and that goes pretty
smoothly with httpd installed first, --with-mpm=prefork and any other
apache options enabled, as a dso it or something else can be unloaded
anyway if memory issues with ssl, for instance, are an issue as the
mod_perl (1) docs state. 

Fred's patch is a lifesaver, so patch first:

configures without error, 'make' without error, 'make test' without
error, and then 'make install'. 

thanks for your help!

For more information on the registry scripts refer to the
ModPerl::Registry manpage. (XXX: one day there will a tutorial on
registry, should port it from 1.0's docs).

Finally check that you can run mod_perl handlers. Let's write a response
handler similar to the registry script from the previous section:

MyApache2/Rocks.pm, somewhere where mod_perl can find it. For example
let's put it under /home/dani/httpd/perl/MyApache2/Rocks.pm, and we tell
mod_perl that /home/dani/httpd/perl/ is in @INC, via a startup file
which includes just:
