Thread: apache2 + subversion "undefined symbol: dav_register_provider"

  1. #1

    Default apache2 + subversion "undefined symbol: dav_register_provider"

    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:

    Code:
    # 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:
    Code:
    # Example configuration for a subversion repository
    # see /usr/share/doc/packages/subversion for the full documentation

    Default Re: apache2 + subversion "undefined symbol: dav_register_provider"

    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:

    Code:
    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!
