compile problems...

[Reiner030]

Hello,

I have actual Debian Wheezy setup with Apache 2.2 threaded version:

# lsb_release -d
Description:    Debian GNU/Linux 7.8 (wheezy)
# aptitude show apache2.2-bin | grep ^Version
Version: 2.2.22-13+deb7u4

and your latest commits intents that it should work also with 2.2.

1st I tried the "normal" way to compile the modul but it compiles with a for me unclear $includedir
error message:

# apxs2 -c -i mod_proxy_fcgi.c 
Use of uninitialized value $includedir in concatenation (.) or string at (eval 9) line 1.

But Apache won't load it (long lines breaked for better reading):

2nd I got sources from Debian Testing for makepp and created and installed the Debian Wheezy package - but same problem:

# makepp
makepp: Loading makefile `/usr/src/mod_proxy_fcgi/mod_proxy_fcgi/Makefile'
makepp: warning: `/usr/src/mod_proxy_fcgi/mod_proxy_fcgi/%.lo' depends on itself; circular dependency removed

libtool: link: `%.lo' is not a valid libtool object
apxs:Error: Command failed with rc=65536
.
makepp: error: Failed to build target `/usr/src/mod_proxy_fcgi/mod_proxy_fcgi/%.lo' [1]
makepp: 0 files updated and 1 target failed

To be secure not to miss include/header files I also added package libfcgi-dev and added to be really
sure that nothing can be missed also /usr/include . But there was no changes in above error message. :(

Hope that's a small apache upgrade bug ? Would be nice to have fcgi:// useable by Apache threaded version with Tomcat running to call it on another instance.

Thanks.
