is there any more documentation about the numpy C API than the one at http://projects.scipy.org/scipy/numpy/wiki/NumPyCAPI ?

I don't know anything about C API, but scipy documentation from the website http://www.scipy.org/doc/api_docs/ is dated 14 August 2007, so scipy 0.6.0 doc differs significantly.

Thanks for the link. I just found out that there is a problem with running even the most simple example code. Am I doing anything wrong in this program? It's crashing immediately after the "before" line, using Borland C++ Builder 6 and numpy-1.0.3.1.win32-py2.4. #include <iostream> #include #include #include "numpy/ufuncobject.h" #include int main() { _control87(MCW_EM, MCW_EM); Py_Initialize(); PyImport_ImportModule("numpy"); PyObject *array; int dim[1] = { 5 }; std::cout << "before" << std::endl; array = PyArray_SimpleNew(1, dim, PyArray_SHORT); std::cout << "after" << std::endl; Py_Finalize(); return 0; } Thanks a lot, Thomas

Thanks a lot, that was the problem. There still seems to be a bug in #define import_array(): In my version of __multiarray_api.h, this line ends with "return;", which my compiler doesn't accept. If I replace it by "return(0);" it's perfectly fine. Thomas

I was confused until I checked that page -- you mean 2006, not 2007 :-) So yes, a year out of date instead of a month. -- |>|\/|< /--------------------------------------------------------------------------\ |David M. Cooke http://arbutus.physics.mcmaster.ca/dmc/ |cookedm@physics.mcmaster.ca
