[Buildroot] buildroot building problems

[Yegor Masharsky]

Hi all ,

I'm trying to setup buildroot and uclibc on my host , but something
goes wrong . According to buildroot manual I've downloaded buildroot
using
"svn co svn://uclibc.org/trunk/buildroot" then configured it using
"make menuconfig" and run "make" . After kernel is patched make fails
saying that it could not copy .config file . The output is the
following:

rm -rf /home/aym001/buildroot/project_build_powerpc/uclibc/linux-2.6.22.10
*** Unpacking kernel source
bzcat /home/aym001/buildroot/dl/linux-2.6.22.10.tar.bz2 | tar -C

cp: missing destination file
Try `cp --help' for more information.
make: *** [/home/aym001/buildroot/project_build_powerpc/uclibc/linux-2.6.22.10/.configured]
Error 1

What do I do wrong ?

Thanks,

Hello Bernhard ,

grep KCONFIG .config returns
BR2_PACKAGE_LINUX_KCONFIG=""

docs/README says :

1) run 'make menuconfig'
2) select the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) Use your shiny new root filesystem.  Depending on which sortof
   root filesystem you selected, you may want to loop mount it,
   chroot into it, nfs mount it on your target device, burn it
   to flash, or whatever is appropriate for your target system.

So I fail at step 4 but don't see where I missed something

Thanks,
Yegor

Yegor,
You need a .config for the kernel as well. In make menuconfig you can select
to run xconfig prior to compiling the kernel. Otherwise run the config tool
yourself and point to the .config file in make menuconfig. Hope this helps?
Paul

Maybe target/linux/Makefile.in could be modified to give an error if
BR2_PACKAGE_LINUX_KCONFIG is unset, rather than just using it blindly?

It already gives an error if the variable is set to a non-existent file.

That would prevent approximately one post/bug report per week.
