The Phidgets Python example code causes a crash in combination with the libphidget rpm supplied by Fedora 14.

Version-Release number of selected component (if applicable):
libphidget.x86_64  2.1.7.20100621-5.fc14

How reproducible:
Always (see steps below)

Steps to Reproduce:
0. Buy a Phidget Interface Kit 8/8/8   ;)
1. yum install libphidget libphidget-devel
2. cd /usr/src
3. wget http://www.phidgets.com/downloads/examples/Python_2.1.7.20101103.zip
4. unzip Python_2.1.7.20101103.zip
5. cd Python
6. python InterfaceKit-simple.py
  
Actual results:

Additional info:
I found out that this problem does not occur when I download the newest source code from phidgets.com:
http://www.phidgets.com/downloads/libraries/libphidget_2.1.7.20101103.tar.gz

./configure
make
make install

After that the Python example code works fine.

Comment 1 Rich Mattes 2010-12-15 03:17:44 UTC

Thanks for the report.  I updated the libphidget package to the latest version, and I think I've solved the error you're encountering.  I guess you downloaded and installed the python modules from the phidget website; I did the same and the example you tried to run seems to work fine now.

The new builds are located at http://koji.fedoraproject.org/koji/taskinfo?taskID=2665003, could you please test them and see if this solves your issue?

Comment 2 Egon Kastelijn 2010-12-15 06:00:33 UTC

Cool! Thnx.

I downloaded the RPMs you generated and installed them.
The Python example works fine now.
The C/C++ example also works.

Great!

I'll see if I can find some Karma around here, once the update pops up on Bodhi.
;)

kind regards,

   Egon
