oct intNDArray functions not working

[Reza Housseini]

Hello,

I'm using the C++ API of Octave to write some code. In using the intNDArray declaration some problems with the functions occurred. Here the example:

#include <octave/oct.h>
#include <octave/intNDArray.h>

DEFUN_DLD(test_intNDArray, args, nargout, "")
{
    octave_value_list retval;
    
    intNDArray<int> BR(dim_vector(3,1),0);
    FloatNDArray BF(dim_vector(3,1),0);
    
    BR(0,0) = 10;
    BF(0,0) = 9.8;
    
    retval(0) = BR.max(0);
    retval(1) = BF.max(0);
    
    return retval;
}

which gives me the following error:

error: /media/extra/Master/Masterarbeit/Octave/dynamic/test_intNDArray.oct: failed to load: /media/extra/Master/Masterarbeit/Octave/dynamic/test_intNDArray.oct: undefined symbol: _ZNK10intNDArrayIiE3maxEi

although it compiles without errors. The FloatNDArray performs the operation without error, so it can't be an linking issue.

Thank you for the help.

Greetings,
