In Include\import.h, line 89-97:

PyAPI_FUNC(PyObject *)_PyImport_FindBuiltin(
    const char *name            /* UTF-8 encoded string */
    );
PyAPI_FUNC(PyObject *)_PyImport_FindExtensionObject(PyObject *, PyObject *);

    char *name                  /* UTF-8 encoded string */
    );
PyAPI_FUNC(int)_PyImport_FixupExtensionObject(PyObject*, PyObject *, PyObject *);


Shouldn't they be the following:

PyAPI_FUNC(PyObject *) _PyImport_FindBuiltin(
    const char *name            /* UTF-8 encoded string */
    );
PyAPI_FUNC(PyObject *) _PyImport_FindExtensionObject(PyObject *, PyObject *);
PyAPI_FUNC(int)_PyImport_FixupBuiltin(
    PyObject *mod,
    char *name                  /* UTF-8 encoded string */
    );
PyAPI_FUNC(int) _PyImport_FixupExtensionObject(PyObject*, PyObject *, PyObject *);

To see the errors, one can install PyCUDA and Theano, and run code at http://deeplearning.net/software/theano/tutorial/using_gpu.html#id1 :


import numpy, theano
import theano.misc.pycuda_init
from pycuda.compiler import SourceModule
import theano.sandbox.cuda as cuda

class PyCUDADoubleOp(theano.Op):
    def __eq__(self, other):
        return type(self) == type(other)
    def __hash__(self):
        return hash(type(self))
    def __str__(self):
        return self.__class__.__name__
    def make_node(self, inp):
        inp = cuda.basic_ops.gpu_contiguous(
           cuda.basic_ops.as_cuda_ndarray_variable(inp))
        assert inp.dtype == "float32"
        return theano.Apply(self, [inp], [inp.type()])
    def make_thunk(self, node, storage_map, _, _2):
        mod = SourceModule("""
    __global__ void my_fct(float * i0, float * o0, int size) {
    int i = blockIdx.x*blockDim.x + threadIdx.x;
    if(i<size){
        o0[i] = i0[i]*2;
    }
  }""")
        pycuda_fct = mod.get_function("my_fct")
        inputs = [ storage_map[v] for v in node.inputs]
        outputs = [ storage_map[v] for v in node.outputs]
        def thunk():
            z = outputs[0]
            if z[0] is None or z[0].shape!=inputs[0][0].shape:
                z[0] = cuda.CudaNdarray.zeros(inputs[0][0].shape)
            grid = (int(numpy.ceil(inputs[0][0].size / 512.)),1)
            pycuda_fct(inputs[0][0], z[0], numpy.intc(inputs[0][0].size),
                       block=(512,1,1), grid=grid)
        return thunk


The interpreter will complain errors like "c:\python33\include\import.h(97): error: explicit type is missing ("int" assumed)" (at least in my case)

In case no one else sees it, Ziyuan is saying that there should be a space after the PyAPI_FUNC() uses.

Yes, although I left out the space after the third PyAPI_FUNC().

@Ziyuan Lin: The issue should now be fixed, can you please confirm?

I can't build the cpython with Visual Studio 2012 because of the following errors:


"D:\Repository\cpython\PCbuild\pcbuild.sln" (default target) (1) ->

Anyway, I replaced Python33/Include/import.h with cpython/Include/import.h directly, and it works well with my sample code. Thank you.


By the way, here's a discussion about the "fci.lib" issue, which suggests replacing fci.lib with cabinet.lib: http://social.msdn.microsoft.com/Forums/vstudio/en-US/3b85f36e-dffe-4589-adc3-13673b349812/missing-fcilib-in-windows-sdk-80?forum=vcgeneral

So it sounds like this specific issue is fixed. If you keep having build issues, Ziyuan, feel free to open another issue with the new problems.
