Re: [Discuss-gnuradio] Windows install guide from Ettus Research: missing important note

[Артем Писаренко]

This is the first thing that came to my mind, but I have to dissapoint you. It's not root cause, because I played a lot with order of folders on PATH and it didn't helped. I used Dependency Walker, but it also didn't helped 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.

Hi Artem,

I saw this myself a while back when experimenting with Qt (outside of GNU Radio).

The cause, for me, was that I had two versions of Qt installed - one came with the PyQt installer, and the other was silently installed by another software package I was using. The problem was that the other application's folder was in my PATH environment variable, and so whenever Python/PyQt would try to open the Qt DLLs that came with PyQt, it would actually open the DLLs from the other application (found in PATH).

You might consider checking whether this is also the case for you?

You can also use a great utility called Dependency Walker to look at which specific DLLs will be opened by the Windows program loader when running an EXE (or loading another DLL).

Kind regards,
Balint

Thanks for the feedback, Artem!

We'll take a look at it today.

On PyQT dependency should be noted, that *you should UNCHECK extra options
(such as "Qt runtime") during PyQT install*.

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