Hello. Talking with moshez and walters on #debian-boot last night, I discovered that the cdebconf gtk frontend is still on the todo list.
I'll be out of town this weekend, away from net access, and I'm looking for a project to work on. So, I began a gtk frontend for cdebconf. The beginning is attached. It sort of compiles with this line: gcc -Wall -g gtk.c -o gtk.so `pkg-config --cflags gtk+-2.0` \`pkg-config --libs gtk+-2.0` -I../../.. -I../../../../debian/build/src well, it compiles but doesn't link with the debconf stuff. I'll work on that. Anyway, I just wanted to get some feedback on this and see if it's feasible, if this is a decent beginning, if anyone else is working on it. If this is a bad idea, I'll go back to the partitioning stuff, but there seems to be a lot of stuff done already there. Anyway, all this frontend has so far is a boolean handler, the rest is a copy of the text handler. I'll poke around the cdebconf tests dir tomorrow, its late. Also, what are people's thoughts on using complete debs, not udebs for X and gtk? it seems like an X based installer on a cd doesn''t have the same space requirements, and d-i should be able to use debs as well as udebs... thanks michael -- michael cardenas | lead software engineer | lindows.com | hyperpoem.net "When making your choice in life, do not neglect to live." - Samuel Johnson
