Cross-compiling for ARM

[David Kramer]

I'm working on a project with a few people, and we want to fool around with 
cross-compiling on Linux x86 (Red Hat 7.3 in my case) for the ARM 
architecture.  I'm supposed to be looking into the toolchain and HOWTO's.  
The problem is, I see a lot of conflicting/ambiguous/irrelevant 
documentation, and it's bumming me out.  A lot of it seems to be for the 
ecos RTOS, or relies on the commercial GnuPRO tools.

I found one FAQ that looked great:
http://www.objsw.com/CrossGCC/
But then I start finding lines like 4.1.1 that say "The author has more 
familiarity with Newlib than Glibc so Newlib will be used in all examples 
below.".  It definitely came off more of a "I did it and this worked for 
me" than "This is the canonical way to do it, and here are one or two 
variants".

The best advice I found was here:
http://sources.redhat.com/ml/crossgcc/2001-01/msg00076.html
In it, Kai Ruottu <kai dot ruottu at luukku dot com> says that he found 
pretty much what I did, and goes on to say that it's OK to look at all 
these FAQs out there, but you need to study the GCC documentation on how to 
do it first, so you understand the details and such.

That sounds like a great idea, but I don't know if I'm too frustrated or too 
stupid, but I can't seem to find any documentation on the gnu.org site.  If 
anyone knows where to look on that site, I'd appreciate a pointer.

Part of me wants to follow the directions around for cross-compiling for my 
Sharp Zaurus, but I'm not sure how much of that would be applicable to 
other embedded ARM applications.


So I'm open to pointers, suggestions, and as always, ridicule.  Thanks in 
advance for any of these.
