Re: [Ltib] First steps LTIB, programming for Linux

[Stuart Hughes]

Hi Lukasz,

I can't answer specifically about the LPC3250, but here are some general
pointers.

LTIB will build your operating system and you can configure it to
include the libraries you need including GTK.

These libraries exist on the target machine when you deploy for runtime
support and also on the host where you run LTIB.

On the host where you run LTIB you can use whichever IDE you find best.
 The important thing you must do though is set it up to:

* use the same cross compiler suite for your target that LTIB did

* make sure it uses the rootfs/usr/{include,lib} area built by LTIB for
linking (to GTK libraries etc).

Everyone has a different view/preference for development environments.
One options would be not to use an IDE and to create an LTIB package for
your application.  This is really no more than writing a .spec file
which includes the build rules.  There are examples/templates in LTIB
that show how to do this.  Doing this has a number of advantages including:

* the cross build environment is setup for you (gcc is the cross
compiler, the -I/-L pkg-config paths are setup for you)

* your package is managed and you can control dependencies etc

* your builds will be repeatable

* you can make an integrated release when you're done

Regards, Stuart
