I have:
| top_builddir=/usr/local/share/apache22

But I think that's ok, because "rules.mk", "config_vars.mk" ... are in:
/usr/local/share/apache22/build

I have:
| include /usr/local/share/apache22/build/rules.mk


> /usr/local/build/rules.mk includes $(top_builddir)/build/config_vars.mk

I have:
| include  $(top_builddir)/build/config_vars.mk

No, the apr include dir is not part of EXTRA_INCLUDES. The apr inlude dir is
defined in APR_INCLUDEDIR.

BTW: A normal apxs run is using the script defined in APR_CONFIG
(/usr/local/bin/apr-1-config) to get e.g. the apr include dir.


OK, with using apxs I can build and install the module:
# cd modules/fcgid
# apxs -c mod_fcgid.c fcgid_bridge.c fcgid_conf.c fcgid_pm_main.c \
        fcgid_protocol.c fcgid_spawn_ctl.c fcgid_proctbl_unix.c \
        fcgid_pm_unix.c fcgid_proc_unix.c fcgid_bucket.c fcgid_filter.c
# apxs -i -a mod_fcgid.la

And and least I have to set e.g.:
| FcgidIPCDir /var/run/
| FcgidProcessTableFile /var/run/fcgid_shm
Or Apache can't start: No access/exists to the default values of these two
directives. Maybe e.g. TMPDIR should be used as default?


So for me there is only one problem left. php_apc does not work together
with mod_fcgid. And the question, who the guilty party is (mod_fcgid or
apc...). Only the first request for a file is working, a core dump at the
second, and so on.

Hope that helps.
