I have installed KDE 3.4 into the rom, both libs and base. I had to remove some packages (xmms, abiword and others), and made a 90 MB root partition ( i have a c860).
Both are huge, but the size can be reduced, for future builds (kdelibs-3.4.1).
At first, when compiling, one might make use of DO_NOT_COMPILE, and omit compiling stuff like kdeprint and others, especially arts.
example:
DO_NOT_COMPILE="arts debian kdeprint"
For a complete list please take a look at the archive, every subdirectory is an option if i got the configure script right.
After building kdelibs and kdebase, one might remove changelogs, wallpapers, sounds, help-templates for languages other than "en",
I would like to compile kde myself, and while i am at it, the rom as a whole. Are there any special instructions i have to follow, or is it as easy as to download pdaxrom-builder, all the sources, the toolchain and then go?
