Hi Vitek,
so it's good, that it works for you. To get a more complete picture of
the situation (especially for our documentation), would you mind telling us:
- what's the output of /usr/sbin/apxs -q LDFLAGS ?
- are there also shared libraries in /usr/lib, like libapr-1.so ?
- do libapr-1 and libhttpd2core really get linked in statically, or are
the libtool "la" files used to link them in dynamically (if you get a
mod_jk.so out of the process, what does ldd mod_jk.so give for
dependencies).
I don't know Cygwin well enough, but I would be surprised if they
compiled everything statically (but hey, sometimes there *is* a surprise
...).
Regards,
Rainer

Ok so I have solved it,
The cookbook to compile mod_jk on Cygwin

$(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'''

Now I see it complains about APR libraries:

However I do have apr1 and aprutil1 installed , perhaps it is again
something as weird as with WSGI compilation that required to hack
libtool as it was unable to recognize cygwin shared libraries ....
Any ideas?

libtool: link: warning: undefined symbols not allowed in

I managed to get rid of the libtool's --silent flag however no more
information provided. Is there somebody able to pinpoint what is wrong
with it, e.g. specific libraries it is missing (like
c:\java\jdk1.5.0\include\cygwin which is of course wrong but perhaps
harmless), guess the
the build process can be confused by OS name (as Cygwin is no OS at the end).
Again any help would be much appreciated.

Unfortunately no Cygwin experience yet. If you compiled your httpd under
Cygwin, I expect you have a /my/path/to/httpd/bin/apxs file?
What happens if you try
configure --with-apxs=/my/path/to/httpd/bin/apxs
and then make?
Do you get the error you mentioned? Any indication, which symbols are
meant there ("undefined")?

Hello gentleman,
did anybody of you ever attempted to have Apache 2 on Cygwin equipped
with mod_jk?
The main documentation page counts Cygwin as a supported platform:
http://tomcat.apache.org/connectors-doc/webserver_howto/apache.html
However I have never found binary release for Cygwin. The Win32 builds
do not work with Cygwin. Perhaps it would be possible to build from
source on cygwin however all my attempts ended with:
libtool: link: warning: undefined symbols not allowed in
i686-pc-cygwin shared libraries
We a complex existing Cygwin-based system (Apache, WSGI, Subversion,
Trac, Ssh ...) so moving out of cygwin is not an option (while
mod_proxy may be an option). Does anybody have any experience running
mod_jk on Cygwin? Any help would be greatly appreciated.
