[Openembedded-users] External toolchain + uclibc

[Rahul Gundecha]

Here is what I am doing -
I am having a external toolchain based on glibc. I want to build uclibc
library of OE. And compile other packages against uclibc library for ARM.

I have a recipe external-toolchain-<vendor>.bb in openembedded/recipes/meta/
directory.
Problem here is I do not find file /usr/include/bits/uClibc_config.h in
oe/tmp/sysroots/ directory which signifies that this is a uclibc system.

Pasting my local.conf file contents below.
DL_DIR = "${PWD}/oe_sources"
TMPDIR = "${PWD}/tmp"
