Hi openpkg-users,
while trying to build the apache mod_jk connector for apache2 with
openpkg (the tomcat-adapter in openpkg's current-directory only supports
apache 1.3) it seems that i've found some misconfiguration in the
build-process of openpkg's apache2-package when building with
with_core_so=yes. The resulting apache runs fine, and is able to load
DSO from foreign sources, but i found no way to create a DSO for mod_jk
with the apache's apxs-tool. The created apxs seem's to disallow the
creation of shared-objects.
After some try-and-error-modifications in apache2.spec i figured out,
that apache's configure-option --disable-shared is responsible for this.
So i removed that option in case of "with_shared_core=yes", and was able
to build mod_jk with the help of the new apxs. To still avoid the
creation of shared modues by default, i now use
--enable-mods-shared=none, when building with with_shared_core=yes.
Here's the diff to the original apache2.spec:
55c55,60
< %option with_shared_core no
---
> %option with_shared_core yes
>
> # if we set with_shared_core, we can specify a list of DSO-modules in
> # single quotes or use one of the predefined special values
> # "none", "all" and "most"
> %option mods_shared none
105a111,116
> NOTICE2: This is a derived version of the original apache2 package
> of openpkg. It modifies the original configuration to enable
> DSO support for apxs. This is necessary, if you want to build
DSO-modules
> with this apache's apxs-instance.
>
>
209a221,224
> --enable-mods-shared=%{mods_shared} \
> %endif
> %if "%{with_shared_core}" == "no"
> --disable-shared \
218d232
< --disable-shared \
As you can see, i've added a new build option "mods_shared", that allows
to create some of apaches modules as DSO. But the default remains "none".
I'm not sure, if what i've done is contrary to openpkg's
avoid-shared-objects strategy, but since the resulting httpd doesn't
contain any DSO, as long as you don't change the default-value of
"mod_shared", the resulting httpd still shouldn't use any shared
objects, unless you add some extra DSO in the httpd.conf.
With this apache's apxs, i was able to build the tomcat connector module
mod_jk. For those who need this as well, i add my apache2-mod_jk.spec,
which is based on the tomcat-apache.spec of openpkg's current-directory:

------- END OF SPEC -------------
my changes to the original spec-file were:
- change the package-name to apache2-mod_jk
- use just the connector-package from apache, not the whole tomcat-package.
- set the same compiler/linker-environment as in apache2.spec before the
configure-call. without got some error-messages saying something about
"tagged versions". i didn't understand this at all, but some
code-sniffing and try-and-error lead to this solution.
- remove the apache-1.3-specific build-code
- remove the not needed dependencies
- change the dependency from apache to apache2so, which is the name i
gave my modified apache2-package. in case of my changes would become
part of the openpkg-apache2-package, it would be necessary to ensure
that the apache2 was build with "with_shared_core=yes".
I was also able to build an apache2 with static linked mod_jk --
unfortunately not as an openpkg-rpm. For this, it was necessary to:
1. build apache2
2. build mod_jk and modifiy apache2-source-tree
3. rebuild apache2
Since I didn't see a way, how to do this in a package external to the
core apache2-package, i preferred the solution with the DSO. On the
other hand, if mod_jk would be an build-option of apache2-package this
would allow allow a smoother integration of the mod_jk-configuration.
but this was to complicated for my basic understanding of rpm.spec-files.
I have to admit, that I don't understand deeply, what i did here (i'm
still an openpkg novice, and not a specialist in unix-build-prcesses at
all), and most of it is the result of try-and-error. But maybe it helps
some other openpkg-guru to build a correct package for apache2 with
mod_jk-support.
Since i don't know how to configure and use the %track-section in the
spec file, you should give it a close look, in case you want to use it.
Hope that helps others, who, like me, try to use apache2/java/tomcat in
an openpkg environment.
