Subject Re: [users@httpd] Apache module compatibility
Date Thu, 28 Aug 2008 18:09:21 GMT
Thanks for your reply. I do expect the binary releases are tied to platform
specific information (OS, processor architecture, dependent libraries). If
the only thing change is Apache server version, does it work? Or I should be
prepared to add a dimension to my binary release matrix. The grid for the
new dimension is the last part of the version number of Apache.

So, let me ask my question specific to a single platform again. Is Apache
a.b.y backward compatible with a.b.x in terms of loading modules previously
compiled with a.b.y? Do I have to recompile my modules for every single
minor releases?
