kconfig (gkc): help about Makefile

Hi Roman,

I'm currently working on the kernel Makefile ($SRC & $SRC/scripts/kconfig) for adding gkc support but I'm encountering some difficulties... I have written a standalone Makefile for the gkc package which I'm integrating into the kernel's Makefile.

I does not understand why it does not run the GTK detection (l75 in the Makefile). I hope that I am not bothering you but I'm not a guru in this kind of Makefile: it's too elaborated for me.

# Shared Makefile for the various lkc executables:

# conf:	  Used for defconfig, oldconfig and related targets
# mconf:  Used for the mconfig target.
#         Utilizes the lxdialog package
# qconf:  Used for the xconfig target
#         Based on QT which needs to be installed to compile it
# gconf:  Used for the gconfig target

# Based on GTK which needs to be installed to compile it

Thanks, Romain.

OK.

Not OK. Replace with:
gconf-objs := gconf.o kconfig_load.o

Looks OK, but I do not know the gtk package

The rest looks OK as well.
