Description

As reported here, when using Sun C++ on Solaris, ...

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:

#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'
