[Buildroot] Error during make

[Buildroot] Error during make

[Daniel Endres]

Hello Guys,

I'm trying to build a toolchain as well as rootfs for a mipsel device.

Therefore I'd like to use buildroot. The problem is that I'm getting
some undefined references errors during the awk-build. Obviously the
errors are due to a missing math-library.

I've just downloaded the latest snapshot in the first place and tried
the svn-version later on.
Both giving me the same errors.

I've just done a "make menuconfig" for buildroot, changed the target to
mipsel, exited and hit "make".
I don't know if I'm wrong, but shouldn't a clean build succeed ?

Below I've posted my error-log. Hopefully some could point me in the
right direction.
Thanks in advance,

Greetings Daniel

Well, as you correctly state you need stuff from libm, so configure your
libc to provide the required libm functionality.

see docs/README

Hello Bernhard,

first of all, thanks for your quick reply.
Ok, missing libm functionaliy seems to be the problem. But how do I 
configure my libc-library? You did mean "configure your uclibc" didn't you?

I've tried to configure my uclibc as stated in the docs/Readme via "make 
uclibc-menuconfig", but there isn't any possibility to configure libm 
support?

Am I digging in  the wrong spot ?

Thanks for your help

Greetings, Daniel
