%general-entities; ]> GMP If you are compiling this package on a different CPU then you plan to run the CLFS system on. You must replace GMP's config.guess and config.sub wrappers with the originals. This will prevent GMP from optimizing for the wrong CPU. You can make this change with the following command: mv -v config{fsf,}.guess mv -v config{fsf,}.sub Prepare GMP for compilation: CPPFLAGS=-fexceptions CC="gcc -isystem /usr/include" \ CXX="g++ -isystem /usr/include" \ LDFLAGS="-Wl,-rpath-link,/usr/lib:/lib" \ ./configure --prefix=/usr --enable-cxx --enable-mpbsd Compile the package: make The test suite for GMP is considered critical. Do not skip it under any circumstance. Test the results: make check Install the package: make install Installed libraries libgmp.[a,so], libgmpxx.[a,so], libmp.[a,so] Short Descriptions libgmp Contains the definitions for GNU multiple precision functions. libgmp libgmpxx Contains a C++ class wrapper for GMP types. libgmpxx libmp Contains the Berkeley MP compatibility library. libmp
