GMP is the GNU Multi-Precision library: see http://www.swox.com/gmp/ for more information. When compiling the GMP library, do not forget to enable the C++ interface: add --enable-cxx to the configuration options.

Hi Bill,

As you can see, your C++ compiler (/net/whistler/auto/users/tovrea/local/sol2/bin/g++) is not finding symbols that belong to the standard library (libstdc++). This might mean the compiler has not been properly installed.

What happens if you try to compile and link by hand the program that configure is using, that is:

#include <gmpxx.h> #include <climits> #include <string> #include <sstream> #include <iostream>

#if __GNU_MP_VERSION < 4 || (__GNU_MP_VERSION == 4 && __GNU_MP_VERSION_MINOR < 1) || (__GNU_MP_VERSION == 4 && __GNU_MP_VERSION_MINOR == 1 && __GNU_MP_VERSION_PATCHLEVEL < 3) #GMP version 4.1.3 or higher is required #endif

int main() { std::string header_version; { std::ostringstream s(header_version); s << __GNU_MP_VERSION << "." << __GNU_MP_VERSION_MINOR; // Starting from GMP version 4.3.0, the gmp_version variable // always contains three parts. In previous versions the // patchlevel was omitted if it was 0. if (__GNU_MP_VERSION_PATCHLEVEL != 0 || __GNU_MP_VERSION > 4 || (__GNU_MP_VERSION == 4 && __GNU_MP_VERSION_MINOR >= 3)) s << "." << __GNU_MP_VERSION_PATCHLEVEL; header_version = s.str(); }

std::string library_version = gmp_version;

if (header_version != library_version) { std::cerr << "GMP header (gmp.h) and library (ligmp.*) version mismatch:\n" << "header gives " << header_version << ";\n" << "library gives " << library_version << "." << std::endl; return 1; }

if (sizeof(mp_limb_t)*CHAR_BIT != GMP_LIMB_BITS || GMP_LIMB_BITS != mp_bits_per_limb) { std::cerr << "GMP header (gmp.h) and library (ligmp.*) bits-per-limb mismatch:\n" << "header gives " << __GMP_BITS_PER_MP_LIMB << ";\n" << "library gives " << mp_bits_per_limb << ".\n" << "This probably means you are on a bi-arch system and\n" << "you are compiling with the wrong header or linking with\n" << "the wrong library." << std::endl; return 1; }

mpz_class n("3141592653589793238462643383279502884"); return 0; }

And, if that fails, what happens if you compile and link by hand a simple "Hello world!" C++ program, like

#include <iostream>

int main() { std::cout << "Hello world!" << std::endl; }

All the best,
