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

[John S. <jo...@st...>]

Hi Mike -

The links at http://wiki.calivia.com/index.php/Mod_cplusplus seem to be  
broken - although I find a single patch file at  
http://wiki.calivia.com/svn/sipx-ebuilds/www-apache/mod_cplusplus/ 
files/1.4.3.patch that contains both patches.

I've applied the test_auth.cpp portion (thanks).  For the configure.in  
patch - it would be best to find a more portable way to determine the  
shared library suffix instead of patching it.  On gentoo is libc.so  
somewhere other than /usr/lib?  I can fix configure to look in other  
places for it.

Also, does make install not work for you?  I notice your instructions  
manually copy things in, I will fix that if its not working.

Thanks - Send me the above info and the patches should be applied in  
the next release.  I look forward to more patches!

John
