Re: [Modcplusplus-devel] Apache segfaults w/mod_cplusplus-1.4.3

[Michael S. <mic...@ca...>]

Hi

compilation of 1.4.3 now works fine on my Gentoo system. I created a 
beta quality ebuild for mod_cplusplus-1.4.3 (tested on 4 x86 machines). 
I'm using mod_cplusplus together with SIPfoundry.org's sipXpbx, a 
software PBX for the SIP protocol.

Instructions on how to use my ebuild can be found here: 
http://wiki.calivia.com/index.php/SIPfoundry.org_sipX_Ebuilds_for_Gentoo_Linux

Anyone to test the ebuild and give feedback is more than welcome.
Mike
