This is probably way too big a question to ask here, but I'm hoping
someone can help me.  I have inherited a gcc 2.95.3 cross development
tool chain, which has been working fine to build for my powerpc-linux
target machine.  I'm building the kernel and user programs fine.  I'm
beginning to find as I add things in that I'm missing libraries.  Today
its libresolv which I need for pump.  Some questions:

1. Do I really need to go back and build my own tool chain?  I've tried
grabbing 2.95.3 sources and building by running configure with
--target=powerpc-linux, but I get some missing include file errors
building libgcc2.a.  I'm on a 405GP (no fp).  Should I even bother doing
this?

Only if you run into trouble with your old compiler.
If and when you decide to rebuild the compiler, see
http://kegel.com/crosstool for a recipe you can follow.

2. On my intel development machine I see that libresolv.a comes from
glibc-devel-2.2.5-34.  I have gcc-2.96-110 for my compiler.  Should I go
find a version of glibc-devel that matches up with my existing 2.95.3
tools?  How will I know if its the right version?

Again, http://kegel.com/crosstool (if you study it, and compare it
with Karim's book) will help show you how to build the glibc of your
choice.

3. Better yet, is there somewhere I can just obtain a reasonable tool
chain that's ready-built for my target machine?  Complete with libraries?

That same URL can show how to build a reasonable toolchain for the ppc405
without any thought on your part, if you choose to not read and
understand the script.  It's always better to read and understand, though.

Sorry for the newbie type questions.  I have the "Using and Porting GNU
CC" book, but am finding it a little too Stallman-esque to follow.  Anyone?

Your question is quite reasonable.

BTW, which glibc does your toolchain use?
