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: -------START OF SPEC ------------- ## ## apache2-mod_jk.spec -- OpenPKG RPM Package Specification ## Copyright (c) 2000-2005 OpenPKG Foundation e.V. <http://openpkg.net/> ## Copyright (c) 2000-2005 Ralf S.

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. andi ______________________________________________________________________ The OpenPKG Project www.openpkg.org User Communication List openpkg-users@openpkg.org
