Discussion¶

I got mod_waklog to work on apache 2.2 at least.

I've found a lot of info in this posting:
https://lists.openafs.org/pipermail/openafs-info/2009-May/031480.html

Stephen Quinney's patches are available here:
http://old.nabble.com/mod_waklog-tt33632100.html

Aaron Knister's patches here:
http://userpages.umbc.edu/~aaronk/waklog/patches_for_git

I downloaded mod_waklog from git, and applied the patches in this order:
patch -p1 < ../patches_aaron_knister/fix_build_scripts.patch
patch -p1 < ../patches_aaron_knister/have_stropts_h.patch
patch -p1 < ../patches_aaron_knister/gnu_source.patch

patch -p1 < ../patches_stephen_quinney/modwaklog-weakcrypto.patch
patch -p1 < ../patches_stephen_quinney/modwaklog-libs.patch

As I said, mod_waklog seems to work perfectly. However, I haven't got filedrawers to work yet. It does not seem to work with PHP 5.4.11 and Smarty 3.1.13.

I've read that it should work with PHP 5.x, but apparently not with 5.4, though I think I managed to fix that. (by loading some module statically instead of using "dl" - dynamically loaded modules, which is deprecated in 5.4).

Smarty 3.1.13 seems to be more difficult, I just get strange error messages.

I've found a note somewhere that it does not work with Smarty 2.x, and that version 1.x works. Maybe version 3.x has the same problem, and we need to downgrade to version 1.x.
