MPC

The order in which these libraries are built is important! MPC depends on GMP and MPFR.

Extract the tarball somewhere and create a folder outside of the source directory.

tar xf path/to/mpc-1.0.3.tar.gz
mkdir mpc-build

Configure MPC.

cd mpc-build
../mpc-1.0.3/configure --prefix="$HOME/.local/share/cross" --with-mpfr="$HOME/.local/share/cross" --with-gmp="$HOME/.local/share/cross" --enable-shared --disable-static LDFLAGS="-Wl,-rpath=$HOME/.local/share/cross/lib"

Build and install MPC.

make -j8
make install
