Tomcat, Apache and mod_jk.so problems.

[Espen]

I just can't seem to get the mod_jk module to work with Apache.
The first problem is that I'm not able to create the mod_jk module the normal way. After I configure the tomcat-connectors source with apxs and do a make (both go trough without errors), there still isn't any mod_jk module under the apache-2.0 directory. These are the only files that are there:

Makefile
Makefile.apxs.in
Makefile.vc
Makefile.apxs
Makefile.in
NWGNUmakefile
bldjk.qclsrc
config.m4
mod_jk.a
mod_jk.dsp
mod_jk.lo
mod_jk.c
mod_jk.la
mod_jk.o

But after a lot of google searching, I found a site that used the following command after make:

gcc -shared -o apache-2.0/mod_jk.so apache-2.0/*.o

This actually created a mod_jk.so file, which I copied to my apache/modules/ directory, and then added the following to httpd.conf:

LoadModule jk_module          modules/mod_jk.so
JkWorkersFile /usr/local/apache/workers.properties
JkLogFile     /usr/lib/apache-tomcat/logs/mod_jk.log
JkLogLevel    info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkOptions     +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat     "%w %V %T"

But when I start apache I get this error (line 54 is the LoadModule line):

httpd: Syntax error on line 54 of /etc/httpd/httpd.conf: Cannot load /usr/local/apache/modules/mod_jk.so into server: /usr/local/apache/modules/mod_jk.so: undefined symbol: jk_log

I hope someone here can help me with this, because it's driving me nuts.

Tried switching to Ubunto, but it still isn't working. Isn't there anyone who can help?

Hei Espen,

Looks like your mod_jk.so file are missing 'jk_log' (which you probably already know). I've never compiled this module myself, but there may be other options you need to pass to the compiler/linker in order to include 'jk_log'.

I'd look into makefiles, README, etc. in the source directory first.

Cheers

I apologize, there is actually a difference with ubuntu (including that I have to add CFLAGS=-fPIC to the configure command). The problem is no longer jk_log, but jk_set_log_format. I have searched all the makefile's and documents, but I cannot seem to find any reference to it.
So the error I get now is:

httpd: Syntax error on line 54 of /etc/httpd/httpd.conf: Cannot load /usr/local/apache/modules/mod_jk.so into server: /usr/local/apache/modules/mod_jk.so: undefined symbol: jk_set_log_format

Since it still gave an undefined symbol error, I was stupid and assumed that it was the same symbol.

Found this after a quick Google search, and there seems to be a problem in a particular version of the mod_jk sources. Not sure which version you are trying, as you didn't bother to mention that, but here's the link: http://servlets.com/archive/servlet/...me=tomcat-user

I've also found that site, but I couldn't see if there was any solution.
I'm sorry for leaving out version info, but here it comes (better late than never):

Ubuntu 5.10 64bit
Apache 2.2.0
Tomcat 5.5.16
Jakarta-tomcat-connector 1.2.15
