[Ltib] Re: add -DZ_PREFIX

[Stuart Hughes]

Hi Henry,

I've just checked in the last update to Savannah CVS and now for the
imx31ads the following package should build if you select them:

expat, freetype, fontconfig, libpng, libjpeg, libtiff, glib2, DirectFB,
cairo, atk, pango, gtk2

Ideally just selecting gtk2 should be enough to select all the dependent
pieces, but I'm not sure I've got that side of things completely
finished yet.

Maybe you can see if you can get gtk2 (gtk+) to build for you too and
then perhaps you have enough for you to try building firefox ?

Let me know how you get on.

Regards, Stuart
