Hi Olivier,

I see in the INSTALL file make xconfig needs the full kernel source. I have
fiddled around some with symlinks, but I can't get make xconfig to work:


In the media_build directory I have first created a symlink to the freshly
downloaded kernel source:
$ ls -l
scripts -> /home/cedric/downloads/linux-3.4.3/scripts/

Then I issued the following command:
$ make xconfig
make -C /storage/home/cedric/tmp/linuxtv-mediabuild/media_build/v4l xconfig
make[1]: Entering directory `/storage/home/cedric/tmp/linuxtv-mediabuild/media_build/v4l'
make -C /lib/modules/3.3.7-1-ARCH/build -f /storage/home/cedric/tmp/linuxtv-mediabuild/media_build/v4l/Makefile.kernel
config-targets=1 mixed-targets=0 dot-config=0 SRCDIR=/lib/modules/3.3.7-1-ARCH/build
v4l-qconf
make[2]: Entering directory `/usr/src/linux-3.3.7-1-ARCH'
  HOSTCC  scripts/basic/fixdep
scripts/basic/fixdep.c:433:1: fatal error: opening dependency file scripts/basic/.fixdep.d:
Permission denied
compilation terminated.
make[3]: *** [scripts/basic/fixdep] Error 1
make[2]: *** [scripts_basic] Error 2
make[2]: Leaving directory `/usr/src/linux-3.3.7-1-ARCH'
make[1]: *** [/lib/modules/3.3.7-1-ARCH/build/scripts/kconfig/qconf] Error
2
make[1]: Leaving directory `/storage/home/cedric/tmp/linuxtv-mediabuild/media_build/v4l'
make: *** [xconfig] Error 2

The directory scripts/basic/.fixdep.d is not present:
$ ls -lA scripts/basic/
total 20
-rw-r--r-- 1 cedric cedric 10782 Jun 17 20:21 fixdep.c
-rw-r--r-- 1 cedric cedric     7 Jun 17 20:21 .gitignore
-rw-r--r-- 1 cedric cedric   671 Jun 17 20:21 Makefile

Next I goto my kernel directory, and run make xconfig from here:
$ cd downloads/linux-3.4.3
[cedric@cedric linux-3.4.3]$ make xconfig
  HOSTCC  scripts/basic/fixdep
  CHECK   qt
  HOSTCC  scripts/kconfig/conf.o
  SHIPPED scripts/kconfig/zconf.tab.c
  SHIPPED scripts/kconfig/zconf.lex.c
  SHIPPED scripts/kconfig/zconf.hash.c
  HOSTCC  scripts/kconfig/zconf.tab.o
/usr/bin/moc -i scripts/kconfig/qconf.h -o scripts/kconfig/qconf.moc
  HOSTCXX scripts/kconfig/qconf.o
  HOSTLD  scripts/kconfig/qconf
scripts/kconfig/qconf Kconfig
#
# using defaults found in arch/x86/configs/x86_64_defconfig
#

and now back in the media-build directory I run make xconfig again:
$ cd tmp/linuxtv-mediabuild/media_build/
[cedric@cedric media_build]$ make xconfig
make -C /storage/home/cedric/tmp/linuxtv-mediabuild/media_build/v4l xconfig
make[1]: Entering directory `/storage/home/cedric/tmp/linuxtv-mediabuild/media_build/v4l'

config-targets=1 mixed-targets=0 dot-config=0 SRCDIR=/lib/modules/3.3.7-1-ARCH/build
v4l-qconf
make[2]: Entering directory `/usr/src/linux-3.3.7-1-ARCH'
  HOSTCC  scripts/basic/fixdep
scripts/basic/fixdep.c:433:1: fatal error: opening dependency file scripts/basic/.fixdep.d:

make[3]: *** [scripts/basic/fixdep] Error 1

make: *** [xconfig] Error 2

I don't have the directory .fixdep.d:
$ ls -lA scripts/basic/
total 40
-rwxr-xr-x 1 cedric cedric 14561 Jul  1 20:45 fixdep
-rw-r--r-- 1 cedric cedric 10782 Jun 17 20:21 fixdep.c
-rw-r--r-- 1 cedric cedric  2836 Jul  1 20:45 .fixdep.cmd
-rw-r--r-- 1 cedric cedric     7 Jun 17 20:21 .gitignore
-rw-r--r-- 1 cedric cedric   671 Jun 17 20:21 Makefile

What did I miss?
Best regards,
Cedric
