Hi Wim, > I configure using : > > ./configure --prefix=/users/ackooij/softs/gcc-4.2.1SunOS/ > --with-gmp=/logiciels/public/gmp-4.1.4 > --with-mpfr=/logiciels/public/mpfr-2.2.0 --with-gnu-as > --with-as=/logiciels/public/binutils-2.16/bin/as --with-gnu-ld > --with-ld=/logiciels/public/binutils-2.16/bin/ld > --enable-languages=c,c++,fortran --disable-libgcj > --build=sparc-sun-solaris2.8 As per the instructions <http://gcc.gnu.org/install/configure.html>, ./configure (running configure in the same directory as the source code, or any subdirectory thereof) is not supported. That may-or-may-not be one of the factors that is causing problems. HTH, --Eljay
