I committed my patch for tools/kerneldoc/subsys. Except for not generating the PDF part, this is now the same config which I use to generate the online version. While writing the commit log I noticed that I did more changes than I thought…
So anyone who wants to generate the Doxygen docs of some FreeBSD kernel subsystems on his own, can do it now. Adding more subsystems is easy, just make a copy of one the the existing Doxyfile-* files – keep the same naming scheme – and change the contents. Everything else is handled automatically.
I also added a link to the FreeBSD wiki. It is not at a prominent place (near the end of the main page), but at least someone can find the link to the my FreeBSD-doxygen page there.
I solved my WP problems.
The permalink problem was because of a missing .htaccess file. I created one with write permissions for WP, and changed the permalimk setting back.
The white-on-white issue was solved by setting CONCATENATE_SCRIPTS to false in wp-config, so it seems to be a caching problem somewhere. Later I will take some time to switch back and flush some caches (at least where I have the rights to do it).
