Subject svn commit: r952007 - /httpd/httpd/trunk/acinclude.m4
Date Sun, 06 Jun 2010 22:05:18 GMT
Author: rjung
Date: Sun Jun  6 22:05:17 2010
New Revision: 952007

URL: http://svn.apache.org/viewvc?rev=952007&view=rev
Log:
make shared moduled and module set "most" the default.

Static building can be achieved with --enable-mods-static
or as previously using --enable-MODULE=static.
The existing --enable-mods-shared still works for
compatibility with existing build scripts.

Modules build with --with-module=... will still be build static.
For dynamic builds of external modules there is apxs.

The default set of modules os now "most". To build a small
set of modules use the new "few".

If APR doesn't support DSOs we fall back to static binding.
