Developers/mod_caml/apache 2.0

Please make sure you are using mod_caml >= 1.3.4, since earlier versions had a bug with Apache 2.0.

Apache 2.0 contains a bug which prevents mod_caml (or indeed any modules which use PCRE) from working directly. The bug report is here:

http://issues.apache.org/bugzilla/show_bug.cgi?id=27550

You must build a patched version of Apache 2.0.

First download the Apache source code, and apply this patch.

patch -p1 < patch.diff
make distclean
autoconf

Next configure Apache. The important options are --with-mpm=prefork which disables multithreading and --with-external-pcre which uses your system installed PCRE, hopefully the same one that OCaml PCRE was linked against:

./configure --with-mpm=prefork --with-external-pcre --prefix=PREFIX

Now make and install Apache in the normal way:

make
su
make install

Now you can build a mod_caml module, and it should work with Apache 2.0.

(Thanks to Jesse D. Guardiani for additional information about this topic).
