Hello,
I'm a bit of a newbie and I ran into some issues using gmp with boost.
After building gmp-5.1.2, I tried to build a simple file:
boostMathExample.cpp, based on the documentation (using the multiprecision
library + referencing gmp):
//////////////////////////////////////////
#include
using namespace boost::multiprecision;
int main(int argc, const char *argv[])
{
mpz_int v = 1;
// Do some arithmetic:
for (unsigned int i = 1; i <= 1000; ++i)
v *= i;
std::cout << v << std::endl;
}
///////////////////////////////////////////////
I received the following missing symbol errors when trying to build:
g++ -I ~/Dev/C++/gmp-5.1.2 -I ~/Dev/C++/boost boostMathExample.cpp -O2 -o
boostMathExample
Undefined symbols:

========================================
I'm running the following version of g++:
i686-apple-darwin10-g++-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3)
I configured gmp, version 5.1.2 with the following flags:
./configure --enable-cxx CXX=g++ CXXFLAGS=-O2 CC=g++ CFLAGS="-g -O2"
and then ran "make" and "make check".
Any insight would be appreciated.
Thanks,
Fred
