apache2 + subversion "undefined symbol: dav_register_provider"

English Applications
#1

hi,

system: opensuse 11.4 x86_64
kernel: 2.6.37.6-0.7-desktop

so i wanna set up an svn server, thus subversion-server. the apache2 itself works as expected.

so i followed this instruction (GERMAN) about setting it up.

however, starting (reloading) gives me this output:

# service apache2 reload
Reload httpd2 (graceful restart)

httpd2-prefork: Syntax error on line 116 of /etc/apache2/httpd.conf: Syntax error on line 30 of /etc/apache2/sysconfig.d/loadmodule.conf: Cannot load /usr/lib64/apache2/mod_dav_svn.so into server: /usr/lib64/apache2/mod_dav_svn.so: undefined symbol: dav_register_provider

The command line was:
/usr/sbin/httpd2-prefork -f /etc/apache2/httpd.conf

this forum post suggests that the apache2 wasn’t compiled with the needed options.

my subversion.conf looks like this now:

As i thought, dav must be loaded before dav_svn. however, i edited the wrong file. apparently /etc/apache2/sysconfig/loadmodule.conf gets overwritten each (re)start by /usr/sbin/rcapache2 . thus, one must edit this file and in there the variable “APACHE_MODULES=” whereas you MUST MAKE SURE, that dav is loaded BEFOR dav_svn…

for example:

APACHE_MODULES="actions alias rewrite auth_basic authn_file authz_host authz_groupfile authz_default authz_user autoindex cgi dir env expires include log_config mime negotiation setenvif ssl userdir php5 mod_dav dav_fs auth_digest dav_svn"

i’ll file this as a bug report later…

thx!
