Hints on compiling Newlib

[Ian Seyler <ian dot seyler at returninfinity dot com>]

Hello everyone,

I am trying to compile Newlib so that it can be used with the
Operating System (for x86-64 systems) we are developing.

I have downloaded the latest source (1.19.0) and am tying to compile
it in an Ubuntu 11.04 64-Bit VM.

I run this to generate the makefile:
../newlib-1.19.0/configure --target=x86_64-pc-none
I then had to adjust the makefile to tell it that the target programs
are the same as the host programs (as I am on the same architecture, I
don't need a cross-compiler setup?)

Running make looks good other than it is compiling with the "-m32"
argument instead of "-m64". Eventually the build will fail with
"Error: bad register name" because it does not recognize the 64-bit
register names (probably because it looks to be compiling a 32-bit
binary).

How can I force it to compile to 64-bit binaries?

Thanks in advance,
-Ian
