Iam unable to install mod_python on red hat and encountering the following error.

did anybody come across such problem.
when i use "make" i get the following error.

/usr/include/features.h:164:1: warning: this is the location of the previous definition

Probably tell what you are doing
http://linuxsilo.net/docs/smart-questions_en.html

Version of Redhat ? EL ?
The used python ? ( EL5 has 2 : python(default) and python26 ).
Version of mod_python ?

And why compile ? There are packages. Can be installed with yum :
mod_python mod_python26 python26-mod_python

..

i am trying to install a software called indico which needs apache and mod_python and python 2.6+ installed to use the indico software.
But i having trouble when installing the mod_python. when i follow the instructions given in the README file on it to configure and install to be used with apache i get this error.

the version of redhat i have is Red Hat 4.4.5-6, Linux version 2.6.32-131.12.1.el6.i686 and the version of mod_python is 3.2+. The mod_python could not be found using yum. so, the mod_python tar file was used to install.

I am able to configure as given in the README file but when i use the make command i get the following error message.



# make

problem solved...

Change the mod_python-3.2.10/src/connobject.c script in the line 112 to this "!(b == APR_BRIGADE_SENTINEL(bb) ||". Then it worked.
