hey,
I have a firmware for an USB module I can already control by visual C. Now I want to port this to python. for this I need the octopus library which is written in c. I found a file called octopus_wrap which was created by SWIG!
then I found a makefile which says:
python2.5:
swig -python -outdir ./ ../octopus.i
gcc -fPIC -c ../../liboctopus/src/octopus.c
gcc -fPIC -c ../octopus_wrap.c -I /usr/include/python2.5
gcc -fPIC -shared octopus_wrap.o octopus.o /usr/lib/libusb.so -o _octopus.so
python2.4:
swig -python -outdir ./ ../octopus.i
gcc -fPIC -c ../../liboctopus/src/octopus.c
gcc -fPIC -c ../octopus_wrap.c -I /usr/include/python2.4
gcc -fPIC -shared octopus_wrap.o octopus.o /usr/lib/libusb.so -o _octopus.so
win:
gcc -fPIC -c ../../liboctopus/src/octopus.c -I /c/Programme/libusb-win32-device-bin-0.1.10.1/include
gcc -fPIC -c octopus_wrap.c -I /c/Python25/libs -lpython25 -I/c/Python25/include -I /c/Programme/libusb-win32-device-bin-0.1.10.1/include
gcc -fPIC -shared *.o -o _octopus.pyd -L/c/Python25/libs -lpython25 -lusb -L/c/Programme/libusb-win32-device-bin-0.1.10.1/lib/gcc
clean:
rm -f octopus* _octopus*
install_python2.4:
cp _octopus.so /usr/local/lib/python2.4/site-packages/
cp octopus.py /usr/local/lib/python2.4/site-packages/
install_python2.5:
cp _octopus.so /usr/local/lib/python2.5/site-packages/
cp octopus.py /usr/local/lib/python2.5/site-packages/
I dont know how to handle this but as far as I can see octopus.py and _octopus.so are the resulting output files which are relevant to python right?
luckily someone already did that and so I put those 2 files to my "python26/lib" folder (hope it doesnt matter if it´s python 2.5 or 2.6?!)
So when working with the USB device the octopus.py is the library to work with!
Importing this file makes several problems:
>>>
Traceback (most recent call last):
File "C:\Users\ameise\My Dropbox\µC\AVR\OCTOPUS\octopususb-0.5\demos\python \blink_status.py", line 8, in <module>
from octopus import *
File "C:\Python26\lib\octopus.py", line 7, in <module>
import _octopus
ImportError: DLL load failed: module not found.
and here´s the related line 7 :
import _octopus
So there´s a problem considering the .so file!
What could be my next step?
I know that´s a lot of confusing stuff but I hope anyone of you could bring some light in my mind!
thy in advance
