Subject Re: mod_jk in Cygwin
Date Tue, 05 Feb 2008 10:51:12 GMT
Ok so I have solved it,

The cookbook to compile mod_jk on Cygwin

  * Download source distribution (no Cygwin binaries available)
  * '''http://apache.mirror.superhosting.cz/tomcat/tomcat-connectors/jk/source/'''
  * '''tomcat-connectors-1.2.26-src.tar.gz'''

   wget http://apache.mirror.superhosting.cz/tomcat/tomcat-connectors/jk/source/tomcat-connectors-1.2.26-src.tar.gz
   gzip -d tomcat-connectors-1.2.26-src.tar.gz
   tar -xf tomcat-connectors-1.2.26-src.tar
   cd tomcat-connectors-1.2.26-src/native
   ./configure --with-apxs=/usr/sbin/apxs2

  * Hack Makefile building Apache 2.0 module
    * '''apache-2.0/Makefile'''
    * target '''mod_jk.la'''
    * Added statically linked libraries for '''apache2-devel, apr1,
aprutil1'''

mod_jk.la: mod_jk.lo $(APACHE_OBJECTS)
	$(LIBTOOL) --mode=link ${COMPILE} -no-undefined `${APXS} -q LDFLAGS`
-o $@ -module -rpath ${libexecdir} -avoid-version mod_jk.lo
$(APACHE_OBJECTS) /usr/lib/libapr-1.la /usr/lib/libhttpd2core.la
/usr/lib/libaprutil-1.la

  * Now the '''make''' succeedes in creating '''mod_jk.so'''
