No matching constructor for initialising Array1D

[dvalters]

Managed to reproduce a bug reported by @fclubb using the clang-static analyzer (so I assume they were trying to use clang to compile(?)

Anyway clang (version?) does not like this:

include/TNT/tnt_sparse_matrix_csr.h:97

rowptr_(M, r), colind_(nz, c), dim1_(M), dim2_(N) {}

The full error is this:

1 error generated.

Then a bunch of notes/suggestions from clang:

include/TNT/tnt_array1d.h:63:11: note: candidate constructor not viable: no known conversion from 'const int *' to 'const int' for 2nd argument; dereference the argument with *
                 Array1D(int n, const T &a);
                 ^
include/TNT/tnt_array1d.h:64:11: note: candidate constructor not viable: 2nd argument ('const int *') would lose const qualifier
                 Array1D(int n,  T *a);
                 ^
include/TNT/tnt_array1d.h:62:11: note: candidate constructor not viable: requires single argument 'n', but 2 arguments were provided
        explicit Array1D(int n);
                 ^
include/TNT/tnt_array1d.h:65:14: note: candidate constructor not viable: requires single argument 'A', but 2 arguments were provided
    inline   Array1D(const Array1D &A);
             ^
include/TNT/tnt_array1d.h:61:11: note: candidate constructor not viable: requires 0 arguments, but 2 were provided
                 Array1D();
                 ^

(Repeats for every include of tnt.h)

I have the same problem but on a different project with tnt. And I found this may be helpful. https://lists.freebsd.org/pipermail/freebsd-ports-bugs/2013-July/258663.html
