Hmm, so building C++ programs for mb-uclinux?  Although I have to 
wonder, if they make no output, how you know they work?  A philosophical 
question perhaps? :)

Those complaints about the toolchain are ancient - these days building 
mb-gcc and friensd is a lot easier (under a Linux box at least - haven't 
tried lately under Windows).  I have a script that I wrote that does 
most of it automagically, I'll dig it out and send it to the list.

Grab a copy of the gnu sources from the xilinx website and you should be 
right to go.

My feeling is that there's not much if anything you'll need to do in the 
compiler, so much as getting STL port and all of the build environmetn 
stuff in uClinux-dist working for Microblaze.  Also there's the init and 
fini preamble/postamble support in the uClibc runtime libraries as well.

Cheers,

John
