compilare sparc-gcc e sparc-binutils su CENTOS:

sudo yum install gmp-devel
sudo yum install mpfr-devel 
(scaricarle da internet e usare rpm --force --nodep se non le trova)

//
export TARGET = sparc-sun-solaris2.8
export PREFIX = /opt/$TARGET-toolchain
export SYSROOT= $PREFIX/sysroot

sudo mkdir $PREFIX
sudo mkdir $SYSROOT
