Did you update GMP or MPFR in the last week? From: http://www.mpfr.org/faq.html When I link my program with MPFR, I get undefined reference to __gmpXXXX. Link your program with GMP. Assuming that your program is foo.c, you should link it using: cc link.c -lmpfr -lgmpMPFR library reference (-lmpfr) should be before GMP's one (-lgmp). Another solution is, with GNU ld, to give all the libraries inside a group: gcc link.c -Wl,--start-group libgmp.a libmpfr.a -Wl,--end-group See INSTALL file and ld manual for more details. Moreover, if several GMP versions are installed (e.g., one provided by the system and a new one installed by some user), you must make sure that the include and library search paths are consistent. Unfortunately, on various GNU/Linux machines, they aren't by default. Typical errors are: undefined reference to `__gmp_get_memory_functions' in make check when GMP 4.1.4 is installed in /usr/{include,lib} (provided by the system) and GMP 4.2.1 is installed in /usr/local/{include,lib} (installed by the user with configure, make, make install). -- Pinski
