Microblaze uClibc

Hi folks,

This is my first post to the uClibc list.  I've just completed the core 
 kernel port for uClinux 2.4.x onto the Xilinx Microblaze, a 32 bit 
RISC softcore microprocessor that runs on Xilinx FPGAs.  Next stop is 
creating uClibc support for microblaze.

As part of the uClinux CVS distro provided by Snapgear, I have the 
uClibc source tree etc, and am wondering the best way to go about 
introducing a new arch into uClibc.

The microblaze kernel port is based heavily on the v850 port, and I plan 
to do the same for the uClibc support.  I've duplicated the 
v850-specific stuff in the uClibc tree and mapped it across for 
microblaze, like the setjmp/longjmp, and so on.  I've also created a 
microblaze.config file in uClibc/extra/Configs.

By doing the above, make gets part way into uClibc but fails primarily 
because libgen.h is not in my gcc include path (oh, I'm working under 
Cygwin BTW).  I could hack the Makefile but I don't think this is the 
right way to go.

Am I going about this the right way, or do I have to go "higher" than 
this and use buildroot etc?  I searched the archive to see if Miles 
(Bader) had asked any of the same questions when he did the v850 port a 
couple of years back, but didn't find anything particularly 
enlightening.  Miles are you still listening here?  Any words from the wise?

Any assistance greatly appreciated.

Thanks,

John
