%general-entities; ]> GMP cross tools This package and the next two - MPFR and MPC - will be installed into /cross-tools because GCC requires them to build. If you are building with a host which has 32-bit user-space with a 64-bit capable CPU, cross-tools GMP will attempt to link with 64-bit libraries. Add the following variable during configure to force GMP's ABI: ./configure ABI=32 Prepare GMP for compilation: ./configure --prefix=/cross-tools --enable-cxx \ --disable-static --enable-cxx This tells GMP to enable C++ support. --disable-static This tells the GMP package not to compile or install static libraries, which are not needed for the Cross-Tools Compile the package: make Install the package: make install
