Hello,
I am new to GNU Radio and I followed the new windows install directions listed in the thread "Successful installation of GNURadio 3.6.4.1 on Window XP and Windows 8" for my Windows 7 machine (intel 64 bit OS). Everything installed okay except when I created a simple chain in the gnu radio-companion (signal source, throttle, and WX UI Scope Sink) the WX GUI Scope Sink freezes before plotting anything.
I followed the directions mentioned in "WX GUI Scope frozen and error-msg gr_vmcircbuf_default_factory: Invalid argument" thread with no success. Namely 1) I created C:\Users\"myname"\.gnuradio\config.conf in notepad with " [wxgui]" ," style = nongl" 2) renamed the openGL file folders in C:\Python27\Lib\site-packages\ directory.
Not sure if this is related, but I can not run the gnuradio-companion.py from the command prompt. In order to run the script I have to open it run it from the python IDE.
Below I included the messages from the GNU Radio Companion and the WxPython window below. The error message listed in the wxPython window was:
"TypeError: ("No array-type handler for type <class 'ctypes.c_ulong'> (value: c_ulong(0L)) registered", <OpenGL.converters.CallFuncPyConverter object at 0x02F8E730>)
Note that the WxPython message is the same message posted in the thread "Gnuradio 3.7.2 Windows?." I could not find a resolution to this problem in the archives or by searching the net so any assistance would be appreciated.
Thank you,
Carl
