SVN configuration problem

Question

Configured the SVN with httpd service including below modules but it gives an error as below:

LoadModule dav_svn_module     /usr/lib/httpd/modules/mod_dav_svn.so
LoadModule authz_svn_module   /usr/lib/httpd/modules/mod_authz_svn.so

error:

Starting httpd: httpd: Syntax error on line 206 of /etc/httpd/conf/httpd.conf: 
Cannot load /usr/lib/httpd/modules/mod_dav_svn.so into server: 
/usr/lib/httpd/modules/mod_dav_svn.so: undefined symbol: 
svn_mergeinfo__remove_prefix_from_catalog

Server version:

Apache/2.2.3 Server built: Nov 12 2008 07:09:27 RHEL 5.4 - 32 bit 

How would you troubleshoot this error message?

Answer 1

This is usually associated with older versions of the libsvn present on your server: see this thread.

Could it be that you still have an older version of the Subversion libraries somewhere?
If so, remove them. mod_dav_svn may be trying to link with the wrong version.

This is assuming that you did update /usr/local/apache/modules/mod_dav_svn.so with the new one.
Otherwise, it could be that mod_dav_svn is the old part and it's having trouble linking with the newer Subversion libraries.

You find the same upgrade advice in this bug report.
