[Numpy-discussion] Numpy and debug symbols

[Carl Kleffner]

Hi,

numpy extensions are linked against python27.dll. I have no idea, if it
works to copy python27.dll side by side to python27_d.dll (I guess not).
But you can try it anyway. The clean way is to get or compile a debug numpy
version linked against python27_d.dll

Regards

Carll
