cygwin arm-elf-linux gcc build failure

Thanks Richard!

That was the problem.

I got rid of the -linux in the arm-elf-linux configuration and I was able to
complete building arm-elf-gcc --with-newlib.

It feels really good to actually complete something!

Well at least for a couple of minutes 8-) 

Then reality starts settling in again (I hate that 8-) 

I still can't build a kernel, or newlib for that matter.

I do appreciate everyone's help. 

Can someone please tell me what libs I need in place to build
arm-elf-linux-gcc? What I'm really shooting for is building uClinux-2.4,
I've spent hours scouring archives, and the web sites of half the people on
this list, I just can't find anywhere that tells me what headers and libs
need to be in place to get the compiler compiled BEFORE having the kernel
compiled.

When I try to build newlib with the arm-elf-gcc I get:

arm-elf-gcc -B/usr/src/build-2.4.x/newlib/arm-elf/newlib/ -isystem
/usr/src/buil
d-2.4.x/newlib/arm-elf/newlib/targ-include -isystem
/usr/src/newlib-1.9.0/newlib
/libc/include -DPACKAGE=\"newlib\" -DVERSION=\"1.9.0\"  -I.
-I../../../../../../
newlib-1.9.0/newlib/libc/stdlib  -O2 -DABORT_PROVIDED -DHAVE_GETTIMEOFDAY
-DARM_
RDI_MONITOR -I../../targ-include
-I../../../../../../newlib-1.9.0/newlib/libc/..
/libc/include -fno-builtin      -g -O2 -c
../../../../../../newlib-1.9.0/newlib/
libc/stdlib/__adjust.c

I know this one is something dumb...

THANKS AGAIN!!!!

I suspect the problem is that you are trying to use newlib with a Linux 
target.  Linux builds demand more than the newlib headers provide and so 
you are running into problems.  If you want a linux target, then you will 
need to obtain glibc and build with that.  If you want newlib, then I 
suggest you use a more appropriate cross configuration, such as plain 
"arm-elf".

Richard.
