Re: [Discuss-gnuradio] GNU Radio 3.6.4.1 Windows 7 Install - Wx UI Scope Sink Freeze

[Bhaskar11]

a. The "No such file or directory" suggests a paths problem.

b. The "Permission denied" suggests an access rights problem. Try logging in with Administrator rights. Windows 7 onwards is very picky with rights issues.

c. The "TypeError: ("No array-type handler for type <class 'ctypes.c_ulong'>" suggests a conflict of library versions.

Some suggested steps to fix:

1. Start with a clean install. Undo all the changes you made with Notepad and directory renaming. Unintall Python, GNURadio, etc. Reboot.

Check that all Python, GNURadio and related directories are empty, otherwise delete manually. Reboot.

2. Login with full Administrator rights. Now install of Python, GNURadio, etc. with the exact versions recommended in the "Successful installation of GNURadio 3.6.4.1 on Window XP and Windows 8" thread.

Do not make any manual changes with Notepad, etc.

3. Check your paths. Did you set the paths correctly in "systems variables" and not "user variables"?

Run a "cmd" window and type "SET" to check all the environment variables for the PYTHONPATH and GRC_BLOCKS_PATH and PATH contents.

Correct the paths if needed.

4. Run your code with full Administrator rights.

5. If "WX UI Scope Sink" still freezes, check if other WX widgets work ok. If they are ok, then try to change the "WX UI Scope Sink" settings.

Let us know what works. Good luck! :)

Hi Carl,

Any progress on this problem? It would be nice to get an answer, but
I'm afraid it's going to take someone who understands Windows better
than I do. Not being able to run gnuradio-companion from the command
line suggests a bigger problem, possibly related to paths, which might
be the cause of something.

Tom
