I have FreeBSD 5.3 and just installed Apache 2.2.3. I just took over sysadmining this box. We work with Zope and VirtualHostMonster, so there's lots of RewriteRules and a proxy is necessary. The problem is configuring the proxy. The old Apache (1.3.3) had the following: LoadModule proxy_module libexec/libproxy.so ClearModuleList AddModule proxy_module libexec/libproxy.so but apparently the new version of Apache doesn't use that code any more. I ran my configure command with --enable-proxy=shared among others and it didn't complain. Nonetheless, I get errors like this: server167# /usr/local/apache2/bin/apachectl -k start httpd: Syntax error on line 56 of /usr/local/apache2/conf/httpd.conf: Cannot load /usr/local/apache2/modules/libproxy.so into server: /usr/local/apache2/modules/libproxy.so: Undefined symbol "ap_dummy_mutex" when I copy libproxy.so over to the new distro and put in the LoadModule command, server167# /usr/local/apache2/bin/apachectl -k start Syntax error on line 576 of /usr/local/apache2/conf/vhosts.conf: // This is where my <VirtualHost *> stuff lives Invalid command 'CacheRoot', perhaps misspelled or defined by a module not included in the server configuration server167# /usr/local/apache2/bin/apachectl -k start httpd: Syntax error on line 56 of /usr/local/apache2/conf/httpd.conf: Cannot load /usr/local/apache2/modules/libproxy.so into server: /usr/local/apache2/modules/libproxy.so: Undefined symbol "ap_dummy_mutex" For some reason, I can't get the old Apache up, either, so I'm trying to resolve the problem with the new one. Please help. Thanks. beno
