%general-entities; ]> GCC cross tools, final GCC requires the GMP, MPFR, and MPC packages to either be present on the host or to be present in source form within the gcc source tree. Unpack these into the GCC directory after unpacking GCC: tar xf ../mpfr-&mpfr-version;.tar.bz2 mv -v mpfr-&mpfr-version; mpfr tar xf ../gmp-&gmp-version;.tar.bz2 mv -v gmp-&gmp-version; gmp tar xf ../mpc-&mpc-version;.tar.gz mv -v mpc-&mpc-version; mpc If you would like to build a C++ compiler in addition to the C compiler, change the following --enable-languages=c option to be --enable-languages=c,c++ instead. A C++ compiler is not required for any of the software included in this book.
