Hi
I am about to make an application from scratch but have allready run into troubles! :-)

I have made a basic setup with configure.ac, Makefile.in etc. By running autoconf, autoheader and automake the configure script gets created as supposed. And the run of configure also seems fine (no errors).

But when i run make the compilation cannot find the gtk/gtk.h header on my system (it is in /usr/include/gtk-2.0/gtk/gtk.h )

You can see my source here : http://code.google.com/p/gtkfractals...wse/#svn/trunk

How du I put the correct -I/usr/include... and -L/usr/include... options into the makefile?

You will have to use 'pkgconfig'.
gtk+-2 has these ".pc" files (also referred to as 'package') :
/usr/lib/pkgconfig/gdk-2.0.pc
/usr/lib/pkgconfig/gdk-x11-2.0.pc
/usr/lib/pkgconfig/gtk+-2.0.pc
/usr/lib/pkgconfig/gtk+-unix-print-2.0.pc
/usr/lib/pkgconfig/gtk+-x11-2.0.pc

I guess, that some pkgconfig recognition is part of autotools.
Some Makefile.in have this line only : PKG_CONFIG = @PKG_CONFIG@
( Please see for yourself in a gtk application or
the gtk+-2 source code itself.)

Examples : Google .. how makefile.in pkgconfig ..

Good luck !

Thanks a lot Knud! :-)

I found this link from your google-search : http://www.mrpt.org/node/74

I modified lines 2-3 in src/Makefile.am :
1. bin_PROGRAMS = fractals
2. CXXFLAGS += `pkg-config --cflags gtk+-2.0`
3. LDFLAGS += `pkg-config --libs gtk+-2.0`
4. fractals_SOURCES = main.cpp

And now it works! :-)
I just had to use CXXFLAGS because I use C++ and not C
