64 Bit version of libnscope.dll? #3

Open mikewarot opened 8 years ago

mikewarot commented 8 years ago

I'm trying to get Python talking to my newly acquired nScope, and it seems the dll is 32 bit, but everything else on my machine is 64 bit.

Could you either post the source, or a 64 bit version of the dll?

Can you provide some more detail? The DLL should be 64-bit. What OS version are you using, how are you loading the DLL, and what compiler and error messages are you getting?

I was using the 64 bit version of IDLE to run it, 2.7.5, if I recall correctly.

I'm now using the 32 bit version of 2.7.11, and it works ok.

I also had to change line 16 of nScopePy.py to the following, as the interactive version of python didn't work

nScopeAPI = CDLL(os.path.normpath(os.path.join(os.path.abspath(os.path.dirname(sys.argv[0])), "../windows/libnscope.dll")))

It works properly in WinPython 2.7.10 - 32 bit

On the same machine, here is what happens when I run things in WinPython 2.7.10 - 64 bit

We've just now gotten this issue reproduced, so we can test out our build process. Most likely, this is a simple build configuration that I overlooked.
