Building current CVS for ARM under cygwin

Building current CVS for ARM under cygwin

[Lewin A.R.W. Edwards]

I'm trying to build gcc (current sources) so that I can compile arm-elf 
executables with Thumb code. gcc 2.95.2 works fine, but doesn't work for 
thumb (the thumb-elf configuration won't work for the OS I'm trying to 
compile, and the vendor suggests to use a more recent snapshot, and the 
-mthumb switch when compiling).

The problem is that somewhere gcc's build process got broken (at least for 
target arm-elf) when compiling under cygwin. But I _NEED_ to use cygwin.

Any help would be greatly appreciated.

My configure line was /src/gcc/configure --target=arm-elf --prefix=/tools 
--exec-prefix=/tools/H-i686-pc-cygwin --with-gnu-as --with-gnu-ld 
--with-newlib -v 2>&1 | tee configure.out

When I make with

make -w all-gcc install-gcc LANGUAGES="c c++" 2>&1 | tee make.out

I get:

Are you trying to use current GCC's arm.md with an older GCC release?
This is not going to work.  define_constants is a new construct.

No, I was using a new complete CVS checkout. The problem turns out to be 
CR/LF (damn cygwin), so I used tr -d '\r' to fix that one file, and got 
much further in the build process. However now it fails linking cc1.exe. On 
the advice of Jonathan Larmour (Red Hat) I've submitted this one to GNAT:

I believe a CVS update will fix this.

I got this error with yesterday's CVS.

As my colleagues would say, "Booty!" (Hence the name of the bootstrap 
module in all our shipping products - BOOTY ;)

Thanks, I'm going to go update my sources now.

  It was a bugged checkin that was quickly fixed: see

http://gcc.gnu.org/ml/gcc-patches/2001-03/msg01550.html

 and the related thread.
