Re: [Discuss-gnuradio] broken gnuplot

[Nemanja Savic]

Hi all again,

actually yes, the problem was due to numpy. Namely, I uninstalled 1.4.1 which I have on my RHEL6 and installed 1.5 or something. During that opengl was somehow deleted and when I installed using package manager, numpy 1.4.1 was installed again.

Ok, so definitely stick with the non-OpenGL version.

As to why it's stopped working for you, I can't say. Can you roll back
to an older version of GNU Radio that you know was working to see if
it's something there? If not, it's something with your system, and we
can't really be much help with that.
