[avr-gcc-list] Trouble compiling avr-gcc > 4.4.4 on Mac OS X Leopard with gcc-4.2

[Jens Bauer]

Hi all,

I'm trying to compile avr-gcc-4.5.3 and avr-gcc-4.6.1 on Mac OS X 10.5.8 (PPC).
My version of the native gcc is 4.2.1; I use this compiler, since gcc-4.0 can 
not compile GMP/MPFR/MPC.

I can successfully build these versions:
    4.2.4
    4.3.0
    4.3.4
    4.4.4

The following versions fail (with exactly the same build script as the above 
versions):
    4.5.0
    4.5.2
    4.5.3
    4.6.0
    4.6.1

As you already know, gcc > 4.3.x requires GMP, so I can successfully build 
several versions of GCC with GMP/MPFR/MPC.

I've not applied any patches yet, and it does not matter at all whether or not 
I build the GMP/MPFR/MPC libraries.

Here's my configure line and various interesting information:

SOURCEDIR="/Users/toolchain/avr-toolchain/source/gcc-4.5.3"
BUILDDIR="/Users/toolchain/avr-toolchain/Build/gcc-4.5.3"


    
WITH="--with-gmp=/Users/toolchain/avr-toolchain/packages/gmp/usr/local/myPkg 
--with-mpfr=/Users/toolchain/avr-toolchain/packages/mpfr/usr/local/myPkg 
--with-mpc=/Users/toolchain/avr-toolchain/packages/mpc/usr/local/myPkg"
    PREFIX="/Users/toolchain/avr-toolchain/packages/gcc/usr/local/myPkg"
    WITH_LOCAL_PREFIX="--with-local-prefix=$PREFIX"
    TARGET=avr

    $SOURCEDIR/$GCC/configure --quiet --program-prefix=avr- --target=$TARGET 
--prefix=$PREFIX ${WITH} $WITH_LOCAL_PREFIX --disable-nls --disable-shared 
--disable-threads --disable-libssp --with-gcc --with-gnu-ld --with-gnu-as 
--with-dwarf2 --enable-languages=c,c++
    make
    make install


I've tried the following before compiling, but it makes no difference:
ln -s "$BUILDDIR/gmp-$GMP_VERSION" "$BUILDDIR/gcc-$GCC_VERSION/gmp"
ln -s "$BUILDDIR/mpfr-$MPFR_VERSION" "$BUILDDIR/gcc-$GCC_VERSION/mpfr"
ln -s "$BUILDDIR/mpc-$MPC_VERSION" "$BUILDDIR/gcc-$GCC_VERSION/mpc"

And finally, here's where the build stops:

---8<-----8<-----8<-----

checking ABI=32
using ABI="32"
      CC="gcc -m32 -std=gnu99"
      CFLAGS="-O2 -pedantic -mpowerpc -no-cpp-precomp -force_cpusubtype_ALL 
-mtune=970"
      CPPFLAGS=""
      MPN_PATH=" powerpc32 generic"
creating config.m4
...
...
libtool: link: ( cd ".libs" && rm -f "libgmp.la" && ln -s "../libgmp.la" 
"libgmp.la" )
make[2]: Nothing to be done for `all'.
mkdir ./mpfr
Configuring in ./mpfr
configure: error: --target is not appropriate for GMP
Use --build=CPU-VENDOR-OS if you need to specify your CPU and/or system
explicitly.  Use --host if cross-compiling (see "Installing GMP" in the
manual for more on this).
make[1]: *** [configure-mpfr] Error 1
make: *** [all] Error 2

--->8----->8----->8-----

I've spent the last many weeks using Google, however, I didn't find a solution 
to this problem.
I believe that the way gcc is built have changed from version 4.4.4 to version 
4.5.0.
If you need any further information, let me know and I'll try my best to 
provide it.

Can anyone tell me what I am missing / doing wrong ?


Love,
Jens
