Re: Trunk: APR.so won't load
Hi All
I had some more time looking into this, and here's some info I can provide.

It seems that ap_strchr is not defined anywhere outside httpd, and not in
any of the shared libs. This seems to create the problem when building
a module with mod_perl or outside the mod_perl source.
I find a somewhat related change by Stas in the past in the Changes file:
bug reports generating code: [Stas]
- add (apr|apu)-config linking info
- show the full path to the config file used to get the data for the
report
The APR and APR::* family of modules can now be used without having
to load mod_perl.so. On *nix, this is done by compiling the needed
functions from the appropriate sources used to build mod_perl.so
