We are currently trying to write a C++ extension for Python which uses the accelerometer that's build into the Nokia N95. The code has been tested on a Windows PC and it's working just fine. The next step was to try and port it to Symbian so that we can actually run it on our Nokia N95. Again, compiling worked just fine and py2sis produced a sis file.
However when we tried to install the file on the device we got the following error message: "Required Application acces not granted". So we did the obvious thing and sent the sis file to Nokia in order to get it signed via symbiansigned.com (we used the "open signed online" option and checked all the available capabilities). Unfortunately that didn't help very much, either. We are still getting the error message and after hours of using Google we are out of ideas.
We also wrote a little HelloWorld-Extension that doesn't use any of the extended capabilities but we still got the error (even after we got it signed from Nokia as well).
It would be really great if anyone could give us a hint on how to solve this problem since we're totally stuck.
