Nevermind, on Ubuntu the request_rec is only 384 bytes for FPC instead
of 412.
But that still does not explain why the handler function is not even
getting called by apache.

OK, after 4 days of pulling my (remaining) hair out I was able to
compile a basic C apache module on Ubuntu 8.04 (apache 2.2.8).
It seems both fpc/lazarus (not working apache module) and the C compiled
(working apache module) one shows
sizeof(request_rec) = 412
sizeof(module_struct) = 56
So the length seems to be the same for for both. Still, the Lazarus
compiled apache module doesn't even load in apache (mod_hello.pp or any
of the other examples included in fpc).
If the exports is included then it loads but doesn't work at all:
modified "mod_hello.pp" from fpc/packages/httpd22/examples/

Not sure why the Lazarus/fpc apache modules do not work on apache 2.2.8
or 2.2.9 on Ubuntu.
The above module is loaded, the handler registering function is called,
but the handler never gets triggered when the module is called from a
browser.

Any suggestions?
Yes: please print the size of the Request_rec (or TRequest_Rec) and the
same record in C. Compare if they are equal. Same for the module record.
If they are not equal, then we know it is a problem with the pascal
definition of this record. I've had to do this exercise about 30 times
myself on various platforms to get it right. Maybe they changed the
size again.
