Hello. As we all know, Apache 2.4 has been released so I have merrily installed and it works fine. We need this to forward external calls to our internal OBIEE installation so we use the mod_wl_22.so module to do this. The module works fine in 2.2.21. and 2.2.22. But with 2.4 I am having issues. First of all I had to manually download then unpack the apr and apr-util. Then Apache worked (the config ended ok). But when I add the relevant info to the httpd.conf (in the same way we do for earlier Apache versions) I get the following error when starting Apache: httpd: Syntax error on line 489 of /mnt/Apache/conf/httpd.conf: Cannot load /mnt/Apache/modules/mod_wl_22.so into server: /mnt/Apache/modules/mod_wl_22.so: undefined symbol: ap_log_rerror I have searched long and hard for a resolution. I have checked this module using ldd but the "undefined symbol" warning is the same as it is for when I check with the same module that works in 2.2.21 / 22. What else can I do? I heard that I could "recompile" the module (which I have taken from our WLS installation in $WLS_HOME/server/plugin/linux/x86_64) but not sure about that. The 2.4 documentation explains, politically, that: "Many third-party modules designed for version 2.2 will otherwise work unchanged with the Apache HTTP Server version 2.4. Some will require changes; see the API update overview." Should I give up and settle for 2.2.22? Any advice much appreciated! Many thanks, rinser
