Hi,

I still like this idea a lot. However, with "make gconfig" I am
seeing a segfault when I click on "Firmware Drivers" in the main menu.
I only see this with these patches applied.

Other than that, they look good to me.


Here's the gconfig info:
rddunlap@chimera:linux-2.6.29-rc6-git5> make ARCH=x86_64 O=xx64 gconfig &
[1] 10722
rddunlap@chimera:linux-2.6.29-rc6-git5> GEN /local/linsrc/tmp/linux-2.6.29-rc6-git5/xx64/Makefile
scripts/kconfig/gconf arch/x86/Kconfig
make[2]: *** [gconfig] Segmentation fault
make[1]: *** [gconfig] Error 2
make: *** [sub-make] Error


and from the kernel log:

gconf[10868]: segfault at 0000000000000070 rip 00000000004111b6 rsp 00007ffff67cd6f0 error 4

Could you tell what distribution are you using? The versions of your
glibc, gtk+2.0, and glibc? If you can correctly build other gtk+
programs?

I have developed these patches on default Fedora 10 i686, it runs
well, and today I have tested it under a latest Gentoo x86_64 desktop,
all seems run well here.

This is on OpenSUSE 10.3 on x86_64.

glibc-2.6.1-18
gtk2-2.12.0-5

I don't know that I have any other gtk+ programs.

Here's a better backtrace; gconfig was built with -g (not -d ??!?).

Your glibc and gtk version not old, the building environment seems
good, but here I don't have a OpenSUSE 10.3 x86_64, really no idea on
how to resolve that problem, maybe I have chance to install a OpenSUSE
10.3 x86_64 these days, the I will try that,

Today I tested these patches on another pristine debian-5.0 (lenny)
x86_64 system, it also performed well.
On systems I tested (glibc 2.6,2.7,2.8, gtk-2.12 or gtk-2.14), it may
report warnings from gtkitemfactory.h and ununsed variables from
images.c, but doesn't matter, after "scripts/kconfig/gconf
arch/x86/Kconfig" run, the gtk gconfig window will display, with
symbol's value quoted well,

/usr/include/gtk-2.0/gtk/gtkitemfactory.h:47: warning: function

The get_symbol_str function is totally moved from mconf.c, and kept
intact, to make it available not only used by menuconfig, but also can
be used by gconfig & xconfig & config,

Maybe you can try to "make gconfig" from a vanilla
linux-2.6.29-rc6-git5 kernel, without these kbuild patches, to check
if your system can configure kernel with gconfig?

Alternatively, you can use this to compile gconfig,

gcc -Wall -Wl,--as-needed -Wstrict-prototypes -O2 -fomit-frame-pointer
-D LKC_DIRECT_LINK `pkg-config --cflags gtk+-2.0 gmodule-2.0
libglade-2.0` -o scripts/kconfig/gconf scripts/kconfig/gconf.c
scripts/kconfig/kconfig_load.c scripts/kconfig/zconf.tab.c -lncurses
`pkg-config --libs gtk+-2.0 gmodule-2.0 libglade-2.0`

this will build a smaller scripts/kconfig/gconf, with less library
dependencies, or try "-O2" to "-O0", "-ggdb" to compute more debuging
information, thanks,

In the same time I found the scripts/kconfig/gconf building command
have superfluous paramters, such as "-lncurses", gconfig doesn't need
ncurses, I will post patches to reduce that later.
