Re: [Plplot-devel] Subscribing to our git feed

Hi Alan I subscribed to the feed, got the latest master, and all is working now on wxWidgetsdemo. on my linux 14.04 it tries to go to Plot() one time, then OnCreate is called, then goes to Plot() again 23:26:43: Debug: wxPLplotwindow::wxPLplotwindow 23:26:44: Debug: frame->Create 23:26:44:

[Plplot-devel] Subscribing to our git feed

Hi Pedro: Phil found his own way of solving the two big Linux wxwidgets issues this evening with his latest series of commits. But from your recent posts it appears you are not yet aware of those commits. To take care of that issue, I strongly recommend you subscribe to our git feed. You do

Hi Alan I am on my commute home right now. But if you want to test if the random number generator is the cause then find the Rand constructor – Rand::Rand() and comment out everything, replacing it with a single line that sets the seed (probably m_seed or something) to a fixed value, like 0.

Re: [Plplot-devel] wxPLplotDemo.cpp -- linux build error

No worries :-) Attached is a patch which I hope should fix things. It is the simplest possible fix as far as I can tell. It does have a while loop with no counter, but unless there is some rather fatal bug in wxWidgets it should never turn into an infinite loop. Alan if you prefer I will add a

[Plplot-devel] I have now pinned down the long pause to a few lines of completely innocuous code.

Hi Phil and Pedro: Please look at the commit message for af41765, and the corresponding part of the source code (lines 1537-1548 of drivers/wxwidgets_dev.cpp). I cannot spot anything between those two uses of the PLPLOT_wxLogDebug macro that would cause the 13-second pause that shows up on the

I'm just generating a test fix. I will send a patch round once it's done. If it works then I'll tidy it up. However you appear to have bumped up the minimum CMake version so I need to reinstall CMake - turns out the latest Windows version requires a manual uninstall first. I'm sure you're not
