Hi folks, I have solved the problem. I found a hint at https://bugs.php.net/bug.php?id=4630
Then I insert into the file libtool archive_cmds="\${wl}-bI:/at/ep/IDIS/opt/httpd2/modules/httpd.exp \${wl}-bI:/at/ep/IDIS/opt/httpd2/lib/apr.exp \${wl}-bI:/at/ep/IDIS/opt/httpd2/lib/aprutil.exp" The same with archive_expsym_cmds Now the httpd (2.2.31) starts without problems and the axis2c module logs in its logfile.

I successfully compile the (apache) httpd 2.2.31 and a httpd 2.4.12 both in 64 bit mode. And without mod_axis.so the httpd's do their work. But with mod_axis2.so I have a core dump of the httpd at the start phase in mod.axis2.c:711 at the call of ap_hook_post_config(...) Unfortunately the core dump don't provide useful information. Has anybody an idea about this issue or can give me a hint where to look around? Dieter Johannsmeier
