I bumped into green, a PDF viewer for the Framebuffer. I would like to compile it, but I am not having much success, although I have installed all the dependencies…
The error I am getting is:

Obviously he can’t find GdkPixbuf, but this construct is defined in:
# ls /usr/include/gdk-pixbuf-2.0/gdk-pixbuf/gdk-pixbuf.h
/usr/include/gdk-pixbuf-2.0/gdk-pixbuf/gdk-pixbuf.h
When I add to the file sdl.c the following line:
#include <gdk-pixbuf/gdk-pixbuf.h>
I am “greeted” with following error:
# make
cc -Os -Wall -c sdl.c $(pkg-config poppler-glib --cflags) $(sdl-config --cflags) -o sdl.o
sdl.c:20:35: fatal error: gdk-pixbuf/gdk-pixbuf.h: No such file or directory
compilation terminated.
make: *** [sdl.o] Error 1
My question is then, how do I “convince” gcc to compile this code?
Thanks in advance,
Oz
UPDATE:
adding the full path to gdk-pixbuf/gdk-pixbuf.h yields:

Kind of an answer, not really fully compiling, but I managed to solve the part where sdl.c fails to compile with:
