Hello, allI'm writing apache module with fpc. When I compile my program on fpc 2.4.4, Apache terminate immediately. But on fpc 2.2.4, Apache and my module will work fine. Code is compiled with no problem. Apache can load module. But the running has problem. Is there anyone who running a module compiled with fpc 2.4.x on Apache? I tested some envirment: - OS: CentOS 5.5 / Fedora 12 - Apache: 2.2.3 / 2.2.17 - Arch: x86_64 - FPC: 2.2.4 / 2.4.2 / 2.4.4 Test code: ----- library lib_mod_simple; {$ifdef fpc} {$mode objfpc}{$H+} {$endif} uses SysUtils, httpd, apr; var mod_simple: module; public name 'mod_simple'; exports mod_simple name 'mod_simple'; function DefaultHandler(r: Prequest_rec): Integer; cdecl; begin Result := DECLINED; end; procedure RegisterHooks(p: Papr_pool_t); cdecl; begin ap_hook_handler(@DefaultHandler, nil, nil, APR_HOOK_MIDDLE); end; begin FillChar(mod_simple, SizeOf(mod_simple), 0); STANDARD20_MODULE_STUFF(mod_simple); with mod_simple do begin name := 'mod_simple.so'; register_hooks := @RegisterHooks; end; end. ----- Compilation options: ----- fpc -Xs -XX -fPIC -dFPCAPACHE_2_2 -omod_simple.so mod_simple.pas ----- LoadModule in httpd.conf: ----- LoadModule mod_simple modules/mod_simple.so ----- Test#1 with CentOS 5.5, Apache 2.2.3, FPC 2.2.4 ----- # gdb httpd (gdb) r -X Starting program: /usr/sbin/httpd -X [Thread debugging using libthread_db enabled] Detaching after fork from child process 28066.

When I access the webserver with browser, apache respond normal page. In test#2, apache shows no error. But process terminate. And when I accessed the webserver, apache didn't respond. It is possible to develop by using FPC 2.2.4. However, the future, I want to compile with a newer version of FPC. Is there any idea to running module with FPC 2.4.x? Thanks, Takashi
There were problems with apache modules that were fixed in the latest FPC SVN (bug report 19184). If you do not want to use the SVN versions of FPC/Lazarus, you can just download the latest packages/fcl-web/src/base/ files from SVN into your project directory and recompile your project.
Also, make sure you compile with the httpd22 directory and that FPC/Lazarus is not accidentally uses httpd13 or httpd20 . The best if you just delete these two directories from your fpc units directory.
