[ITK-users] Error printing vnl_vector_fixed when length is greater than 5.

[DVigneault]

All--

I've encountered a build error when I attempt to print a vnl_vector_fixed,
with length >= 6 only.  I'm on Ubuntu 12.04, using g++ version 4.8.1, and
I'm using a recent development build of ITK from the git repo.  (I've been
having the problem for some time, but have only just figured out how to make
it reproducible.)

Here is the error:

Linking CXX executable dv-subdivision
CMakeFiles/dv-subdivision.dir/dv-subdivision.cxx.o: In function
`std::ostream& operator<< <float, 6u>(std::ostream&, vnl_vector_fixed<float,
6u> const&)':
dv-subdivision.cxx:(.text._ZlsIfLj6EERSoS0_RK16vnl_vector_fixedIT_XT0_EE[_ZlsIfLj6EERSoS0_RK16vnl_vector_fixedIT_XT0_EE]+0x1f):
undefined reference to `vnl_vector_fixed<float, 6u>::print(std::ostream&)
const'
collect2: error: ld returned 1 exit status
make[2]: *** [dv-subdivision] Error 1
make[1]: *** [CMakeFiles/dv-subdivision.dir/all] Error 2
make: *** [all] Error 2

And a minimal example:

#include "vnl/vnl_vector_fixed.h"
#include <iostream>
#include <cstdlib>

int main()
{

//  vnl_vector_fixed<float,5> FV; // No problems
  vnl_vector_fixed<float,6> FV; // Build error
  FV.fill(0);
  std::cout << FV << std::endl;

  return EXIT_SUCCESS;

}
