Passing {{std::numeric_limits<>}} as an lvalue as in the example below results
in undefined symbols for the symbol {{std::numeric_limits<>}} at link time:
{noformat}
#include <iostream>
#include <algorithm>
#include <limits>
int main() {
int i = std::numeric_limits<double>::digits10;
int j = std::min(std::numeric_limits<double>::digits10, 10);
//Undefined Symbols
int j1 = std::max(std::numeric_limits<float>::min_exponent10, 2);
//Undefined Symbols
std::cout << i << std::endl;
std::cout << j << std::endl;
}
Undefined first referenced symbol in file std::numeric_limits<double>::digits10
t.o [Hint: static member std::numeric_limits<double>::digits10 must be defined
in the program]
ld: fatal: Symbol referencing errors. No output written to t *** Error code 1
make: Fatal error: Command failed for target `t'
