Windows install guide from Ettus Research: missing important note

Current guide
missed one important note, which is non-trivial and cause such
users as me to waste a lot of time and nerves fighting obscure DLL
ImportError failures !
On PyQT dependency should be noted, that you should UNCHECK extra
(such as “Qt runtime”) during PyQT install

To help other users on the web experiencing this problem find this:

windows gnuradio python py2.7 PyQt4 PyQwt qtgui ‘QT GUI’

from gnuradio import qtgui

_qtgui_swig = swig_import_helper()

_mod = imp.load_module(‘_qtgui_swig’, fp, pathname, description)
ImportError: DLL load failed:

(ImportError: DLL load failed: The specified procedure could not be
(ImportError: DLL load failed: ═х эрщфхэр єърчрээр яЁюЎхфєЁр.)

Thanks for the feedback, Artem!

We’ll take a look at it today.


This is the first thing that came to my mind, but I have to dissapoint
It’s not root cause, because I played a lot with order of folders on
and it didn’t helped. I used Dependency Walker, but it also didn’t
me a lot. At least, things are more complicated than this suggestion.
Currently I so angry and tired with all this gnu->windows porting shit,
that I have absolutely no interest to investigate it. I just hate it.

Thanks to Artem P… That was a lifesaver tip. I could not find
other way around that error.

But instead of removing all extra options "such as “Qt runtime”, it
enough to remove only the Qt runtime option.

Hi, Ben, please do include it in the web instructions at least as a
for those who do get this error.
