Compile 4.7.1 problems

Installation of prerequisites to the default path will also not work!

The only way I found to get the things work is to install all packets to
exact one path and give all the path information manually to all the
packages and the compiler configure itself:



tar -xjf ../avrdownload/gmp-5.0.5.tar.bz2
cd gmp-5.0.5/
./configure  --enable-cxx --prefix=/opt/linux-gnu_4.7.1
make
sudo make install

---------

tar -xjf ../avrdownload/mpfr-3.1.1.tar.bz2
cd mpfr-3.1.1/
./configure --prefix=/opt/linux-gnu_4.7.1 --with-gmp=/opt/linux-gnu_4.7.1
make
sudo make install

------
tar -xzf ../avrdownload/mpc-1.0.tar.gz
cd mpc-1.0/
./configure --prefix=/opt/linux-gnu_4.7.1
--with-gmp=/opt/linux-gnu_4.7.1 --with-mpfr=/opt/linux-gnu_4.7.1
make
sudo make install

---------
tar -xjf ~/avrdownload/ppl-1.0.tar.bz2
cd ppl-1.0/
./configure --prefix=/opt/linux-gnu_4.7.1 --with-gmp=/opt/linux-gnu_4.7.1
make
sudo make install

-----------

tar -xjf ../../avrdownload/gcc-4.7.1.tar.bz2
mkdir build_linux
cd build_linux
../configure --prefix=/opt/linux-gnu_4.7.1
--with-mpfr=/opt/linux-gnu_4.7.1 --with-mpc=/opt/linux-gnu_4.7.1
--with-ppl=/opt/linux-gnu_4.7.1 --with-gmp=/opt/linux-gnu_4.7.1
--enable-languages=c,c++
make -j8
sudo make install


For me it looks that there is no way to simply copy the prerequisite
packages to the compiler and start configure/make.
