Re: [Discuss-gnuradio] Need to install PyQt4.Qwt5

[Chesir, Aaron M.]

Folks,

 

Never mind. I found some site that has download & installation instructions.

 

Do any of you have any documentation on the “trigger rising edge event” block?

 

Thanks,

 

Aaron

Subject: Need to install PyQt4.Qwt5

 

Folks,

 

I am running CentOS, and am trying to run a flowgraph containing a “trigger rising edge event” block. In my attempt to understand this block, the Internet  directed me to the only descriptive page available: An attempt at a tutorial by the inventor of the block, at the following URL:

 

https://oshearesearch.com/index.php/2015/03/15/a-simple-eventstream-based-burst-plotter-example/

 

The page points to a flowgraph. In this flowgraph is a block “PyQT Complex Time Block” When I click on the “Go” icon of the GRC toolbar, I get the following error message:

 

“plotter_base.py", line 26, in <module>
    from PyQt4 import Qt, QtCore, QtGui, Qwt5
ImportError: cannot import name Qwt5

 

When I type $sudo yum install PyQt4, I am assured that I have the latest version of PyQt4 installed.

When I type $sudo yum install python-qwt5-qt4, I am told that there is no such package available.

When I type $sudo yum install python-qwt5, I am told that there is no such package available.

 

What can I do?

Help.

 

Thanks,

 

Aaron
