Re: [Pyars-users] Cannot load dll

[<ax...@er...>]

Hi, Marco!

As you have already found out, apart from using the right binaries (32bit vs 64bit) and setting the PATH environment variable, there is not really much that you can do (and that can go wrong either). As I wrote in another email, please look at the output of ars.py, it prints out the path settings where the dlls are really searched.

There is another situation, that I can think of: when the Remedy libraries are referencing another lib, and they cannot find that one. But under Windows, I'm used to getting a descriptive error message when this happens. I believe, I used a tool called dependency walker to identify such issues: http://dependencywalker.com/ http://dependencywalker.com/ 

Good luck!
Axel

Hi Axel,
Hi, Marco!

You are saying you are using Win7 x64 with 32 bit Remedy libraries. What I still would need to know, what kind of python are you running? 32bit or 64bit? If you are running 64bit, then it cannot load the 32bit Remedy libraries (and pyARS currently does not support 64bit, just yet).

I'm running python 32bit, as I read about pyARS not working with 64bit yet (but I see checks in cars.py for architecture, and change of the library names in case 64bit is detected, so I'm sure it's looking only at 32bit libs)
If you are running python as 32 bit, then you'd have to check the PATH environment variable. Try e.g.
python ars.py
it will print out the path where it is looking for the libs; make sure that the Remedy libs can be found there.

That's the first thing I checked, the libraries can be found in the path. I also copied them in more than one folder in the path, just to be sure ;) I even moved them to a non 'program files' folder, in case it was a privilege problem, to no avail. I don't think I can trace into CDLL to see exactly what's happening, I see there's a bunch of debug print statements commented out in the code, will try to enable them and see what can I do.

Thanks!
