Programs using wxWidgets-3.0 @3.0.0_2 fails to show GUI on OS X 10.9 Mavericks

Reported by: jxy (Xiao-Yong) Owned by: mojca (Mojca Miklavec)
Priority: Normal Milestone:
Component: ports Version: 2.2.0
Keywords: mavericks Cc: jyrkiwahlstedt
Port: wxWidgets-3.0


The program, gnuplot @4.6.4_0+luaterm+pangocairo+wxwidgets-aquaterm-x11, hangs before showing any plot window.

I also tried a simple hello-world program, which compiles and links fine, but fail to show any GUI window upon starting from the commandline. Backtrace upon ctrl-C shows the following,

comment:3 Changed 8 years ago by jxy (Xiao-Yong)

I'm not familiar with wxwidgets. I attached the minimal hello-world program, `hw_wx.cpp', here. If you can reproduce the issue, and you have an account on their bug tracker, please submit a ticket for me.

Thank you!

PS. compile the program with

clang++ hw_wx.cpp `wx-config --libs` `wx-config --cxxflags` -o hw_wx

I found a way to make the GUI window visible. A simple directory structure, or a so called app bundle works. After putting the binary, hw_wx, in a directory like the following

I can open the program without any issue.

But what can we do with a program like gnuplot?

I don't plan to install 10.9 soon enough to be able to test before the release of wxWidgets 3.0.

But I just realized that while gnuplot doesn't crash on 10.7, it doesn't display anything either. It seems that we need to figure out when this problem was introduced.

I submitted a a but report upstream.

Given that it worked in 2.9.5 it should be easy enough to find the problematic commit.

I attached patch-wxt-mavericks.diff​ for gnuplot. Works for me. Please check. The deprecated procedure SetFrontProcess brings the window to the front.

If you have account for gnuplot bug tracker, please propagate it upstream.

I'm a bit swamped in time to do any decent testing. While I can fix gnuplot in MacPorts, I still believe that this is a problem in wxWidgets, not a problem in all the other software.

Checking which commit caused the problem should be easy enough (just doing bisection between 2.9.5 and 3.0.0-rc1) and in addition to that I strongly suspect that could be a serious candidate to blame. Do you have time/motivation to check if reversing that change makes any difference in unmodified gnuplot (or to check which commit between the two releases is to blame)?

Plus, I just noticed that that particular commit might be problematic for other reasons. It checks for WXOSX instead of WXGTK. And it only removes code from carbon, but not from cocoa. So I need to file a ticket to fix that too.

The following needs some testing:

Can you please test the patch in r113110? I forgot to reference the ticket and I didn't include it into the port yet, but I would like to know if it solves the problem on 10.9. I'm not yet sure, but there is a chance that wxWidgets dependencies need to be revbumped after this change.

comment:12 Changed 8 years ago by mojca (Mojca Miklavec)

Did you manage to test the patch on 10.9?

comment:13 Changed 8 years ago by jxy (Xiao-Yong)

Thanks, @mojca, for your effort. The new patch works perfectly. I guess we can close this ticket now.

comment:14 Changed 8 years ago by mojca (Mojca Miklavec)

Resolution: fixed
Status: newclosed

comment:15 Changed 8 years ago by mojca (Mojca Miklavec)

The fix is in r113320. The upstream is only partially fixed: it's fixed in trunk, but not entirely in 3.0.0.
