RE: arm cross on cygwin

[John Andrews <john at triscend dot com>]

 

Hi Cristian,

 

Man, I feel your pain, cygwin does stink.

 

I think if you run your gcc make with --save-temps and check out prefix.i you'll find in the line were this winnt.h defines a union element called Hint, that it gets changed to int and screws up the typedef.

 

The fix that worked for me was to change Hint to ARM_Hint in $SRC_ROOT/gcc-2.95.2/gcc/config/arm/arm.h and arm.c.

 

It seems to have something to do with the way the cygwin tools name mangle.

 

Hope that helps...

p.s. I'm guessing that's a typo for host=build=i686-pc-cygwin, and you really shouldn't have to call out build or host in any of the configure steps, it should figure it out on its own. Good Luck!

Subject: arm cross on cygwin

    I tried to do a cross on cygwin for arm:

 

    host=build=i686-pccygwin

    target=arm-coff

    src_root=/usr/local/src/gnu

    prefix=/usr/local/arm

 

    when doing:

 

mkdir -p $SRC_ROOT/BUILD/binutils
cd $SRC_ROOT/BUILD/binutils
$SRC_ROOT/binutils-2.10.1/configure --target=$TARGET --host=$HOST --build=$BUILD --prefix=$PREFIX -v
make > make.log 2>&1
make install > install.log 2>&1

 

export PATH=$PATH:$PREFIX/bin
$TARGET-ld --version

 

    I get:

 

$ $TARGET-ld --version
GNU ld 2.10.1

    That's ok (I think).

 

    Then:

 

mkdir -p $SRC_ROOT/BUILD/gcc
cd $SRC_ROOT/BUILD/gcc
$SRC_ROOT/gcc-2.95.2-6/configure --enable-languages=c --target=$TARGET --host=$HOST --build=$BUILD --with-newlib --prefix=$PREFIX -v
make LANGUAGES=c all-gcc > make.log 2>&1

    I get the following make error:

 

gcc -DCROSS_COMPILE -DIN_GCC     -g -O2  -DHAVE_CONFIG_H    -I. -I/usr/local/src/gnu/gcc-2.95.2-6/gcc -I/usr/local/src/gnu/gcc-2.95.2-6/gcc/config -I/usr/local/src/gnu/gcc-2.95.2-6/gcc/../include \

make[1]: *** [prefix.o] Error 1
make[1]: Leaving directory `/usr/local/src/gnu/BUILD/gcc/gcc'
make: *** [all-gcc] Error 2

 

    What seems to be the problem?

 

    As a matter of fact I'm trying to do a new port for a new controller. I started to see what works by now with gcc, but I couldn't get a cross.

I need a cross for a (simple) processor because I want to experiment with machine descriptions.

 

    Can anyone give me a hand?

 

    Thnx,
