You need to set include and lib paths also, something like:

CPPFLAGS='-I/opt/devel/openwrt.git/staging_dir/target-arm_v4t_uClibc-0.9.33.2_eabi/usr/include' \
LDFLAGS='-L/opt/devel/openwrt.git/staging_dir/target-arm_v4t_uClibc-0.9.33.2_eabi/usr/lib' \
./configure ...

Here's package for the OpenWRT:

Thank you, I didn't had the time to retry yet but when I do I'll tell you the results.

Yes, exactly.

Hi Steve,

I am using Linux OpenWRT. Thanks for your reply, I'll try your solution when I have more time. For instance I am using ser2net and it is working really well.
