Hi Jeff, Your solution helped me overcome 1 of those 2 missing symbol reference but 1 still remains. Could you please guide me for this one too.
This is the error now. httpd: Syntax error on line 53 of /usr/local/apache2/conf/httpd.conf: Cannot load /usr/local/apache2/modules/mod_wsgi.so into server: rtld: 0712-001 Symbol ap_accept_lock_mech was referenced from module /usr/local/apache2/modules/mod_wsgi.so(), but a runtime definition of the symbol was not found. Here is the mpm_common.h for me +300 #ifdef AP_MPM_WANT_SET_ACCEPT_LOCK_MECH +301 AP_DECLARE_DATA extern apr_lockmech_e ap_accept_lock_mech; +302 extern const char ap_valid_accept_mutex_string[]; +303 const char *ap_mpm_set_accept_lock_mech(cmd_parms *cmd, void *dummy, +304 const char *arg); Thanks again for your help on this.
