I am working with MSVC6 on Windows XP.
I have created an MSVC project called SHIP
I have a file SHIP.i with "%module SHIP" as the first line (file is below).
I run SHIP.i through SWIG 1.3.24 to obtain SHIP_wrap.cpp and SHIP.py; the
latter contains the line "import _SHIP".
I compile SHIP_wrap.cpp and a bunch of files into a DLL which I have the
linker place in _SHIP.pyd and all goes well.
I start IDLE (version 1.1.1, with Python 2.4.1)
If I open SHIP.py in an edit window and run it (using F5) it runs and if I
do >>> _SHIP.__dict__.keys() I get a load of function names which are like
the ones I'd expect (new_BallScrew for example, where BallScrew is one of my
classes [and is the interface class to the thing I am really interested in
which is already called BallScrewC, before you ask]).
Then I can do things like:
>>> bs = BallScrew(0)
>>> bs.Stop()
>>> del bs
They work fine. Except of course I really want to put all that stuff in a
script, say test1.py:
import SHIP # This is where my problems begin.
bs = BallScrew(0)
bs.GotoLimit(1)
bs.Stop()
del bs
Which I do and when I run test1.py using F5, the line "import SHIP" in
test1.py produces:
ImportError: dynamic module does not define init function (initSHIP)
So, why can I run SHIP.py straight into Python using F5 but not import it
either directly (>>> import SHIP gives the same error) or indirectly when I
am running another file?
One way round this (though I would like to solve this problem as it will
make things easier as the application grows) is for F5 in IDLE not to
restart the Python interpreter.
My aim is for an engineer to be able to use IDLE to write programs to test
hardware without having to learn C++ to access my OO interface. IDLE and
Python are ideal but I want to make it easy for them to load the interface
(i.e. SHIP) between Python and my OO interface.
Many thanks in advance for any helpful suggestions,
Bill
