Hi Michael,
Unfortunately, I do not have any C compilers - nor the knowledge to
compile something with the apache header files in C.
I manually compared the .h/.inc and the translated pascal
structures/records for the two you have mentioned (module_struct and
request_rec) and they seem to have
Try installing an older Apache.
I installed here with XAMMP, Apache 2.2.9 and it just quits without
any error message when loading my Pascal module.
But when using the standard Apache 2.2.6 in Mandriva 2008 it works.
Actually I can't get it to show the page (some config problem?), but
it loads wi
I'm not sure that something is changed to make it incompatible.
The apache modules compiled on windows are only crashing if multiple
requests are coming at the same time, and they are crushing at
function/procedure returns (Yes, on Linux it is even worse, since no
module gets even loaded by apa

Could it be then related to the Apache method of working? Apache has a
non-threaded version and several threaded versions.
In my Mandriva where it didn't crash I installed the non-threaded
version. (not sure if it won't create threads anyway for something
else, even if it works in a non-threaded p

Well, it seems we have some progress now.
The
WaitForThreadTerminate(BeginThread(@__dummythread), 300);
seems to fix it on Windows. At least for 2 concurrent requests. For some
reason Apache cannot seem to want to run more than 2 requests at a time.
If more comes in at a time, the first 2 start
For me in Windows XP 32bit/ FPC (apache modules load properly):
sizeof(request_rec)=416
sizeof(module_struct)=56
For me in Ubuntu 8.04 32bit/ FPC (apache modules don't load):
sizeof(request_rec)=412
sizeof(module_struct)=56
Used exactly the same files to compile a project on Ubuntu but for some
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
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.

Hi Jonas,
This seems to work on Windows (and solves the problem), but on Linux
WaitForThreadTerminate waits forever.
WaitForThreadTerminate(BeginThread(@__dummythread), 300);
apache just waits and doesn't start until I stop the apache loading with
ctrl+c, as if it is in an infinite loop and
