I've got a bit wierd usage scenario.
My C++ library A embeds python.
My library A can be loaded as a service using LoadLibrary/dlopen.
My library A can be unloaded using FreeLibrary.
Now there is another library B which is python extension. Library wants to
use my library A on demand. For varios reasons it also wishes to unload my
library A when it's done.
So here is an order of events:
python script test.py is started
pythons extension library B loaded.
Library B loads library A.
Library B unloads library A.
Library B loads library A again.
In theory this load/unload can happend any number of times. But here is the
problem: it crashes for me. I've tried to pla with it for a bit. My latest
test eliminates any logic from my library A, but following lines:
PyRun_String( "import sys\n", Py_file_input, d.ptr(), d.ptr() );
First time it works fine. Second time around it report an error like this:
"__import__ is unknown"
Perhaps you are calling PyInitialize(); multiple times? That would be a mistake...
