5.11. MPFR-3.1.2

The MPFR library is a C library for multiple-precision floating-point computations with correct rounding.

5.11.1. Installation of MPFR

Prepare MPFR for compilation:

LDFLAGS="-Wl,-rpath,/cross-tools/lib" \
./configure --prefix=/cross-tools \
    --disable-static --with-gmp=/cross-tools

The meaning of the new configure options:

LDFLAGS="-Wl,-rpath,/cross-tools/lib": This tells configure to search in /cross-tools for libraries.
--enable-shared: This tells configure to build MPFR's shared libraries.
--with-gmp=/cross-tools: This tells configure where to find GMP.

Compile the package:

make

Install the package:

make install
