Fail to link with Apache (mod_jk)

[Veli-Matti Hurskainen <vm...@softa.fi>]

Tomcat 3.2.2
Apache 1.3.20
Perl  5.005_03
on linux (a Redhat clone)

I've done:
"apxs -o mod_jk.so -I../jk 
-I${JAVA_HOME}/include  -I${JAVA_HOME}/include/linux  -c *.c ../jk/*.c"
- no errors
and, just to be sure:
gcc -shared -o mod_jk.so *.o
- no errors
and copied mod_jk.so to ...apache/libexec.

Tomcat's been started.

With "Include /usr/local/tomcat/conf/mod_jk.conf-auto" in 
apache/conf/http.conf trying to run apache gives this error:

"Cannot load /usr/local/apache/libexec/mod_jk.so into server: 
/usr/local/apache/libexec/mod_jk.so: undefined symbol: jk_b_set_buffer_size"


What am I still missing?

TIA
