[vsipl++] Problem compiling VSIPL++ Matrix code

[Rutledge, Edward]

Stefan,
That did fix one of the compile errors, but the other still occurs.


Here is the code that fails to compile:

#include <vsip/matrix.hpp>
#include <vsip/initfin.hpp>
#include <vsip/parallel.hpp>

int main(void)
{
  vsip::vsipl prog();
  const vsip::Matrix<vsip::scalar_i> constM(2,2,99);
  vsip::scalar_i a = constM(0,0); // fails to compile
  return 0;
}


Here is the output from the compiler:

% g++ -c Test.cc -I/tools/sourceryvsipl++/include
Test.cc: In function 'int main()':
Test.cc:9: error: passing 'const vsip::Matrix<int, vsip::Dense<2u, int, vsip::tuple<0u, 1u, 2u>, vsip::Local_map> >' as 'this' argument of 'typename vsip::impl::Lvalue_factory_type<Block>::type::reference_type vsip::Matrix<T, B>::operator()(vsip::index_type, vsip::index_type) [with T = int, Block = vsip::Dense<2u, int, vsip::tuple<0u, 1u, 2u>, vsip::Local_map>]' discards qualifiers


Thanks for your help,
-Eddie

No you are not. I can confirm that this should work. Fortunately, there
is a simple work-around:

Insert an additional header on top:

#include <vsip/parallel.hpp>

With that the compile error will go away.

Obviously, we are going to fix this issue such that user code doesn't
have to include that header if they don't otherwise need it.

Thanks,
                Stefan
