[Krishna]

Hi,
       I tried to install syslog-ng.I had earlier installed Bison and Flex.I
even installed libol included with
syslog-ng. Now when I do make install I get the following error's. I am
using REDHAT6.0

In file included from main.c:26:
syslog-ng.h:31:objects.h: No such file or directory
In file included from cfg file.h:26:

NOTE:I had to manually write these error's by making a note of it.
What should I do now?
Any help would be appreciated.
