[Buildroot] uclibc / glibc rfs issues

[Nataraj S Narayan]

Hi

I use at91sam9263ek.

I am on BR  latest git. I was trying to duplicate same .config for
uclibc and for , glibc using COdesourcery toolchain.  Both are
building full, but unfortunately I am getting the following for both
toolchains file systems. It waits endlessly without giving login
prompt.

regards

Nataraj

At the end of build getting this too:-

Sounds like you don't have a /proc directory in your rootfs.

Your device_table.txt refers to a file you don't have in your target
skeleton. What skeleton are you using, what is your .config?

The busybox skeleton is afaik not used much, so that might cause you
trouble. That said, it does have a  /proc entry and no reference to
configfs - Have you changed anything yourself?

Hi

Changed only these by editing .config:-

BR2_DL_DIR="/home/nataraj/buildroot/dl"
 BR2_TARGET_GENERIC_ISSUE="Welcome to MMFSL ucLibc"

So I remove skeleton option?

[Nataraj S Narayan]

Hi Jacmet

When I try the external Codesourcery tool chain on * v2010.02 branch, I get

cp -dpRf package/config/buildroot-config
/home/noy/buildroot/output/build/buildroot-config
Checking external toolchain settings
Incorrect selection of the C library
make: *** [/home/noy/buildroot/output/stamps/ext-toolchain-installed] Error 255


Does that mean latest stable won't work for external toolchain?

regards

Nataraj
