[Boost-users] boost::variant: need help with 'get'

28 May 2004


      I'm trying to use the "get" template with boost::variant but
	can't figure out how to get my compiler to recognize it.

	Here's a simple test program:

---
#include <iostream>
#include <cmath>
#include <string>

#include <boost/variant.hpp>

using namespace boost;
using namespace std;

typedef variant<int, double, string> elem_t;

int main ()
{
    elem_t pi = M_PI;
    double d = get (pi);
    cout << "pi =~ " << d << endl;
    return 0;
}
---
	But my compiler (gcc 3.3.2) tells me:

g++  -I/home/tools/boost-1.31.0   test.cpp   -o test
test.cpp: In function `int main()':
test.cpp:15: error: no matching function for call to `get(elem_t&)'

	I'm using Boost 1.31.0.  Thanks for any help,
