2 Installing MPIR

MPIR has an autoconf/automake/libtool based configuration system. On a Unix-like system a basic build can be done with

./configure
make

Some self-tests can be run with

make check

And you can install (under /usr/local by default) with

make install

Important note: by default MPIR produces libraries named libmpir, etc., and the header file mpir.h. If you wish to have MPIR to build a library named libgmp as well, etc., and a gmp.h header file, so that you can use mpir with programs designed to only work with GMP, then use the ‘--enable-gmpcompat’ option when invoking configure:

./configure --enable-gmpcompat

Note gmp.h is only created upon running make install.

MPIR is compatible with GMP when the ‘--enable-gmpcompat’ option is used, except that the GMP secure cryptographic functions are not available.

Some deprecated GMP functionality may be unavailable if this option is not selected.
