I apologize for my poor description of the issue.
To start of with I have a file platform.inc, which includes the build time
macro definitions,
B_REFSW_OS  = linuxuser
NEXUS_PLATFORM  = 97428
NEXUS_MODE  =
BCHP_CHIP  = 7429
BCHP_VER  = B0

which are used in my source file to make switches,see below code snippet

if (NEXUS_PLATFORM  == 97428) {
{
}
else
{
}

I am trying to include this inc file in the automake file so that the build
variables are available for the sources at the compile time.
This is an existing inc file which is used in the normal makefile, as I am
porting this component to autotools I needed to do the same.

I tried this in my Makefile,am

include platform.inc

this is not working and I am getting compile time errors, like
 NEXUS_PLATFORM undefined, because there is check in the source before
using it like
ifndef NEXUS_PLATFORM: ERROR


can I use the existing inc file as is ? or do I need to port this as to
suit for autotools environment.

Thanks,
Praveen R
