I finally got a simple directfb project to build and run. Trying to use the DirectFB-examples as an example project was a mistake, because the build process in it is a bit too complicated for me.
I It turns out that all that needed to be added to the helloworld makefile was to put the pkg-config directfb calls in the appropriate areas. Here are the two lines in the helloworld makefile that needed to be changed:
CFLAGS = -g -Wall -O2 -MD `pkg-config --cflags directfb`
- and -
LDFLAGS = -g -Wall -O2 `pkg-config --libs directfb`
I figured this out by combining the helloworld files, and some very simple directfb makefiles I found elsewhere—just not for ltib, naturally.
Thank you,
Jeremy

Hi Jeremy,
The DirectFB examples are available in LTIB if you run ./ltib -m config
and select them.
If you're asking about what all the stuff in
dist/lfs-5.1/DirectFB/DirectFB-examples.spec
is all about. Then a good starting point for .spec files for LTIB is to
look at dist/lfs-5.1/helloworld/helloworld.spec
There is also some info in the FAQ online as well as some hints in the
files in the doc directory of the LTIB distro.
For a general reference to rpms, take a look at the Maximum RPM book,
which is online.
Some of the entries in the LTIB .spec files may look a bit weird. This
is a function of cross compiling and safety for the most part. If
there's anything in the helloworld.spec that you can't understand, feel
free to ask.
Regards, Stuart

I'm having a hard time bridging the gap over to LTIB with a DirectFB project.
Does anybody have a simple spec file, package, etc for LTIB that I could use as a starting point? Trying to tease apart the way that the directfb examples are built is beyond my makefile (etc) knowledge.
TIA,
Jeremy
