- Subject: c++ variable-length array?
Using gcc-4.1.1. Info says variable-length array is supported in c++ mode,
but doesn't seem to work:
#include <boost/range.hpp>
#include <vector>
template<typename in_t>
void F (in_t const& in, int size, int x[size]) {}
void G (std::vector<int> const& in, int size, int x[size]) {}
int main () {
std::vector<int> i (10);
int x (10);
F (i, boost::size (i), x);
G (i, boost::size (i), x);
}
g++ -c Test.cc -I /usr/local/src/boost.cvs
