Well I'm strugglingwith it and the gtk mailing lists seem to have went
down this morning


I'm really a novice at autoconf and automake and trying to learn some
gtkmm but I'm running into a problem that I just don't have the
familiarity to solve and I'd like to request some help

I've done a google search for a solution and came up blank so I hope
someone can help me here.

I'm working from documentation here
http://www.gtkmm.org/docs/gtkmm-2.4/docs/tutorial/html/sec-headers-and-linking.html
http://www.openismus.com/documents/linux/automake/automake.shtml#ExampleFiles
http://www.elitecoders.de/mags/cscene/CS2/CS2-10.html
http://www.openismus.com/documents/linux/automake/automake.shtml
and of course the GNU manual and http://sources.redhat.com/autobook/

I need to include the include and library flags into autoconf and
automake and it seems to fail to pickup the gtkmm and gtk library

I'm using this autogen.sh script

then
    echo "This script must be executed directly from the source

    exit 1

The resulting Makefile.in has 

MYAPP_CFLAGS = @MYAPP_CFLAGS@
MYAPP_LIBS = @MYAPP_LIBS@


and the src level Makefile has

MYAPP_CFLAGS = -DXTHREADS -D_REENTRANT -DXUSE_MTSAFE_API

So I'm just lost here.  What am I doing wrong?
