[microblaze-uclinux] Instructions for compiling uClibc?

[Chris Ziomkowski <cziom@xxxxxxxxx>]

I am attempting to use petalinux-v0.30-rc1 in a project. I have been 
working on it for several months, and .40 was not available at the time. 
Upgrading would not be practical at the moment, so if you can reference 
the .30 release in any response that would be ideal.

My current problem is that libc.a is not properly synchronized with the 
kernel system calls.  When I do an ls from busybox, I see all the file 
attributes returned as zero. When I place traps in the kernel, I can see 
the attributes are being properly returned.

When I attempted to start debugging uClibc to figure out what was going 
on, I realized that the code is actually using a precompiled libc.a from 
the toolchain. The source for uClibc is included in the distribution, 
but there are no make rules to actually recompile it.

Can someone suggest the steps I need to take to recompile uClibc? Has 
anyone actually successfully done this for microblaze ? At the beginning 
of this project I did try and get the entire gcc toolchain to recompile 
from source, until I found out that gcc-4.3 won't actually build the 
cross compiler. At that point, I gave up and downloaded the precompiled 
binary. Apparently this already had libc.a and I didn't realize until 
now that uClibc was never built.

Can someone suggest a minimal procedure to rebuild uClibc under the 
petalinux environment? I did check the archives but didn't find 
anything, so I apologize if this has previously been asked and answered 
somewhere else.

Thank you for any assistance,

Chris
