Problem in building compiler

[Valentin Longchamp <valentin.longchamp@epfl.ch>]

Hello,

I'm new to openembedded. I'm working on a robotics research project where we 
are designing a small mobile robot called Marxbot (which is aimed for 
research). The robot embeds an iMX31 custom board. Now I would like to build 
a Linux distro for this robot.

I have used until now LTIB which is the tool proposed by Freescale. However, 
openembedded looks much more complete and clean, since it allows me to 
generate the cross-compiler using the same tool (and not crosstool and LTIB 
as until now).

I have taken Angstrom as a basis for my config files, modifying them to 
something that suits my needs (I haven't changed everything yet, it's only a 
first try, much will change). I have chosen Angstrom, because it seems be arm 
EABI aware, and I need this also to be able to work with Freescale kernel 
patches.

However the build fails for the glibc-intermediate. First, one question about 
the different toolchains that are built. I don't really understand very well 
what are all the different ones: I see cross is aimed for cross-compiling, 
then a native compiler (to be run on the target is built). But what 
does "intermediate" stands for ? What is its goal ?

Now, for my current build problem, the attached error.log file contains the 
error.

Anyone has an idea, according to my config files regarding the cross-compiler, 
of what is wrong here ?

Thank you very much

Valentin Longchamp
