compile error with trunk of apache httpd

[speedkraken]

Compile error due to some change in httpd scoreboard, see this line:

In file included from /usr/include/httpd/scoreboard.h:35,

Same error using pip installation method with mod_wsgi 4.9.4, as well as compiling the trunk/master of mod_wsgi (output shown below).

The 'develop' branch of mod_wsgi is more recent. Tried that branch with the same compile error.

Sorry, there is possibly no simple fix for this. If they have made connection construction completely private that may prevent mod_wsgi even being able to do what it needs to do. This is because mod_wsgi had to replicate the steps to avoid some of the stuff that Apache did internally around adding filters to the connection. So this will likely take some time to investigate and may require a major rewrite of mod_wsgi daemon mode, which given the amount of effort involved and declining number of mod_wsgi users may not be worth the effort. So for now there is a chance will not be able to support Apache httpd 2.5+.

That's really unfortunate. Thanks for the quick and informative reply.
