Another data point, I've just commented out the operator
vector_type&() from MixinVector, i.e.
// operator const vector_type&() const { return _impl; }
// operator vector_type&() { return _impl; }
as the HeightField shape methods:
typedef std::vector<float> HeightList;
....
HeightList& getHeightList() { return *_heights; }
const HeightList& getHeightList() const { return *_heights; }
Were relying upon the MixinVector type conversion methods, and I then get :
home/robert/OpenSceneGraph/include/osg/Shape: In member function
'std::vector<float, std::allocator<float> >&
osg::HeightField::getHeightList()':
/home/robert/OpenSceneGraph/include/osg/Shape:511: error: invalid
initialization of reference of type 'std::vector<float,
std::allocator<float> >&' from expression of type
'osg::TemplateArray<float, FloatArrayType, 1, 5126>'
/home/robert/OpenSceneGraph/include/osg/Shape: In member function
'const std::vector<float, std::allocator<float> >&
osg::HeightField::getHeightList() const':
/home/robert/OpenSceneGraph/include/osg/Shape:513: error: invalid
initialization of reference of type 'const std::vector<float,
std::allocator<float> >&' from expression of type

While different form the HP-UX error, it does look like it might well
be a good lead, perhaps the HP-UX compiler isn't properly picking up
on the operators in MixinVector.
As a further experiment I've changed the operator to:
const vector_type& vector() const { return _impl; }
vector_type& vector() { return _impl; }
And the HeightField code to:
HeightList& getHeightList() { return _heights->vector(); }
const HeightList& getHeightList() const { return _heights->vector(); }
Rebuild seems OK so far.
Robert.
Robert.
