[Numpy-discussion] numarray problem when compiling WrapITK external project PyBuffer

(NumPy community, read on this only seems unrelated)

 

 

I use NumPy 1.0.3 , MSVC 2005 Express, ITK CVS from 23Jul2007, WrapITK for
Python only, wrap for the standard types plus signed short (imho that should
be switched on by default because many DICOM images are in that type). BTW I
had to include the /bigobj compiler switch in the CMakeLists.txt for ITK for
that to work. ItkVtkGlue compiled, but PyBuffer gave errors:

 

1>c:\users\sprevrha\src\insight\wrapping\wrapitk\externalprojects\pybuffer\i
tkPyBuffer.txx(46) : error C2561: 'itk::PyBuffer<TImage>::GetArrayFromImage'
: function must return a value

 

and 

 

1>c:\users\sprevrha\src\insight\wrapping\wrapitk\externalprojects\pybuffer\i
tkPyBuffer.txx(77) : error C2561: 'itk::PyBuffer<TImage>::GetImageFromArray'
: function must return a value

 

at several occasions. At these line numbers, the numarray function
import_array() is called. I checked the numarray code and import_array() is
a #define that does not return a value:

 

#define import_array() {if (_import_array() < 0) {PyErr_Print();
PyErr_SetString(PyExc_ImportError, "numpy.core.multiarray failed to
import"); return; } }

 

I realize that's more a problem with numarray than PyBuffer. Since that's
inline-used the compiler is probably thwarted by the return inside the
macro. Consequently, if I replace the #define with a void to make it a real
function call PyBuffer compiles just fine. 

 

Thanks,

Sven
