Subject httpd build variables
Date Sat, 03 Jan 2009 13:55:24 GMT
Most build variables for httpd are used via APACHE_SUBST, which means 
they get added to build/config_vars.mk.

A) Where to define them?
========================

There are two places, were a lot of ariables are added via APACHE_SUBST:

1) Macro APACHE_GEN_CONFIG_VARS

Defined in acinclude.m4 and called in configure.in.
It contains 75 calls to APACHE_SUBST.

2) Directly in configure.in

It contains about 21 calls to APACHE_SUBST.

Is there any concept, whether APACHE_SUBST for a new variable should be 
put into APACHE_GEN_CONFIG_VARS or directly into configure.in?

I can see that the ones in the macro will be included last into 
config_vars.mk, but apart from that any rules?

B) Should they be installed?
============================

The script build/config_vars.sh deletes a lot of variables before 
installing build/config_vars.mk. Is there any concept, which variables 
should get installed, and which ones should be removed before installing 
the file?

Regards,

Rainer
