Re: mod_mbox compile issue on SuSE Enterprise 10

[Gregory Boyce]

Ok, I found the trigger for the bug, but I'm not sure what the correct fix 
is.

It appears that Apache on SuSE sets AP_DEBUG as part of the EXTRA_CPPFLAGS 
variable in config_vars.mk while Debian does not.  Manually removing 
AP_DEBUG on a SuSE box causes the module to compile and adding it to 
Debian causes the compile to fail.

Currently I can create the correct binaries, but I'm hoping to build an 
RPM which would be easier if I didn't have to modify the contents of 
another package or hack the makefile after it was generated.

Since the rewrite of strchr to ap_strchr is happening in the included 
httpd.h file, its not clear to me what changes I should make to the module 
source in order to get it to compile correctly with -DAP_DEBUG set.

Any recommendations?

I'm currently looking to deploy mod_mbox on a SuSE 10 server, and I'm having

able to shed some light on the issue.

Those functions appear to be defined within httpd.h of the apache2-devel 
package, which is installed.

The system is running the suse version of Apache 2.2.3.  I previously 
compiled mod_mbox on a Debian Etch system with the same apache version with 
no issues.

Do you have any suggestions for things to check for?
