[Pysparse-developers] SpMatrix_API bug

[Dominique O. <dom...@gm...>]

Hello,

Since the new pysparse namespace was introduced, I believe there is a
minor bug in the SpMatrix_API that affects external packages that
build against PySparse.

The bug is in spmatrix_api.h, in the "import_spmatrix" macro. I
believe the first line should read

  PyObject *spmatrix = PyImport_ImportModule("pysparse.spmatrix");

instead of

  PyObject *spmatrix = PyImport_ImportModule("spmatrix");

since spmatrix.so is now located under pysparse/. Not doing the above
change has the following disadvantage. In order to build against
PySparse and to successfully import spmatrix, one would have to add
the directory 'pysparse' to their PYTHONPATH. But then, that defeats
the purpose of the new namespace.

Cheers,
Dominique
