Problem with GCC 4.5.0 and canadian cross compilation

[Sebastian Huber]

Hi,

I had problems building GCC 4.5.0 under MinGW/MSYS, so I tried to build the
cross compiler for the Windows host with a Linux build machine.  The Windows
cross compiler is:

i686-w64-mingw32-gcc (GCC) 4.4.4 20100409 (prerelease)

For the RTEMS tools I use the sources provided by the RPM:

rtems-4.11-arm-rtems4.11-gcc-4.5.0-7.suse11.2.src.rpm

The GCC configure command is:

"$SRCDIR/configure" \
	--prefix=/opt/rtems-4.10-custom \
	--target=arm-rtems4.10 \
	--host=i686-w64-mingw32 \
	--verbose \
	--with-gnu-as \
	--with-gnu-ld \
	--with-newlib \
	--disable-libstdcxx-pch \
	--disable-nls \
	--without-included-gettext \
	--disable-win32-registry \
	--enable-version-specific-runtime-libs \
	--enable-threads \
	--enable-newlib-io-c99-formats \
	--enable-languages="c,c++" \
	--enable-cxx-flags='-fno-exceptions'

The build process works fine and I can use the result to some extend under
Windows, but there is a problem with the multilib installation.  It seems that
it built all multilib components, e.g.

find -name libc.a
./arm-rtems4.10/thumb/vfp/newlib/libc/libc.a
./arm-rtems4.10/thumb/vfp/newlib/libc.a
./arm-rtems4.10/thumb/newlib/libc/libc.a
./arm-rtems4.10/thumb/newlib/libc.a
./arm-rtems4.10/vfp/newlib/libc/libc.a
./arm-rtems4.10/vfp/newlib/libc.a
./arm-rtems4.10/softfp/vfp/newlib/libc/libc.a
./arm-rtems4.10/softfp/vfp/newlib/libc.a
./arm-rtems4.10/fpu/newlib/libc/libc.a
./arm-rtems4.10/fpu/newlib/libc.a
./arm-rtems4.10/newlib/libc/libc.a
./arm-rtems4.10/newlib/libc.a

find -name libgcc.a
./arm-rtems4.10/thumb/libgcc/libgcc.a
./arm-rtems4.10/thumb/vfp/libgcc/libgcc.a
./arm-rtems4.10/libgcc/libgcc.a
./arm-rtems4.10/vfp/libgcc/libgcc.a
./arm-rtems4.10/softfp/vfp/libgcc/libgcc.a
./arm-rtems4.10/fpu/libgcc/libgcc.a
./gcc/thumb/vfp/libgcc.a
./gcc/thumb/libgcc.a
./gcc/vfp/libgcc.a
./gcc/softfp/vfp/libgcc.a
./gcc/fpu/libgcc.a
./gcc/libgcc.a

But a 'make DESTDIR=XXX install' installs only some of them and some also into
strange directories:

find -name libc.a
./opt/rtems-4.10-custom/arm-rtems4.10/lib/thumb/libc.a
./opt/rtems-4.10-custom/arm-rtems4.10/lib/libc.a
./opt/rtems-4.10-custom/arm-rtems4.10/lib/fpu/libc.a

find -name libgcc.a
./opt/rtems-4.10-custom/lib/gcc/arm-rtems4.10/4.4.3/thumb/libgcc.a
./opt/rtems-4.10-custom/lib/gcc/arm-rtems4.10/4.4.3/fpu/libgcc.a
./opt/rtems-4.10-custom/lib/gcc/arm-rtems4.10/4.4.3/libgcc.a

The standard MinGW tool chain from:

ftp://www.rtems.com/pub/rtems/mingw32/4.11

does not seem to have this problem.  Can someone give me a hint?  Which cross
compiler for Windows was used for the standard MinGW tool chain?

Have a nice day!
