Apache 2.4.4 - undefined symbol: ap_log_rerror

[oh...@cox.net]

Hi,

We use a 3rd party module that works fine with Apache 2.2.x, but when we try it with Apache 2.4.4, we get the Subject error:

undefined symbol: ap_log_rerror

>From searching, this is due to changes in Apache 2.4, and what I've seen says that the module needs to be re-compiled for Apache 2.4.

However, we don't have access to the source for the module (it's an Oracle module), and they are not saying when or if they'd modify the module for Apache 2.4.x, so I was wondering if there is any way to work around this.

What I'm thinking/wondering if it'd be possible to LoadModule whatever module exports that ap_log_rerror (and probably other ap_ symbols), then maybe this would work?

So, I was wondering if anyone tell me which shared library/.so that ap_log_rerror is exported from?

Thanks,
Jim

Hi Jeff et al,

Thanks for responding.  I was kind of afraid (but expected) that that'd be the situation :(...

Yours,
Jim

The trouble you'll have is that even if you make up some hacks to get it to
load it will crash and burn (structure field offset and size changes, etc.)
whenever moving from one stable release to another (1.3->2.0, 2.0->2.2,
2.2->2.4, etc.).

It absolutely must be rebuilt from source.

ap_log_rerror is part of the core libraries, see:

http://ci.apache.org/projects/httpd/trunk/doxygen/group__APACHE__CORE__LOG.html

so I think you're going to have trouble making this work without a 
recompile.
