I am trying to build mod_jk for apache on a very tiny Linux system. I have installed gcc, apache2, the JDK1.5 and Tomcat, but I just can't get the thing to compile. I know that ./configure is failing, but it doesn't say why. Here's what I see:

/bin:/usr/local/bin:/usr/bin:.:/usr/local/apache/bin is my path. What is it trying to run? If I do a make, there are no mod_jk.so created.

Any suggestions?

Is your APACHE_HOME variable set?

echo $APACHE_HOME gets
/opt/apache2

The link above helped, but seemed outdated. I was actually building from the latest source (jakarta-tomcat-connectors-1.2.14.1-src). The document you referenced has a section "mod_jk Binaries" that almost makes it sound that any mod_jk.so for linux would work. What do you think? Could I just install one from http://mirror.ipaska.net/apache/jaka...nux/jk-1.2.6/?

It doesn't look like the configure script is using the APACHE_HOME variable.
It might help to find out why. (Try looking in the configure script)
