Do you have a typical platform dependent issue you're battling with ? Ask it here. Make sure you mention your platform, compiler, and wxWidgets version.

I am using gtk2-ansi-release-static-2.6 with g++ (GCC) 3.2.3 20030502 (Red Hat Linux 3.2.3-54).
I have written an application which reads in a script file. Amongst other things, this script file can choose to display graphics, or choose not to. The application is an artificial life simulation and I use the graphical parts for testing during development (making sure animat does what its supposed to do).
I wish to run the simulation with graphics turned off on a cluster of remote machines. The problem is, is that I get the error:
Code: Select all
17:20:57: Error: Unable to initialize gtk, is DISPLAY set properly?
In other words, although I don't want any graphical windows displayed, gtk is still (perhaps understandably) called. Does anybody know how I might get around this problem without writing a seperate and hence gtk-less console application?

Pidel is right.
When you compile wx with GTK (or X) support, all app linked with will intend to initialise gtk.
So if you want to run an wxApp on a X-less platform, you must link it with wxBase.
Just modify env variables is not enough.

Hi, I'm writting app using wxSocketClient and wxSocketEvent. I need to run it on X-less platform.
At first I've tried to inherit from wxEvtHandler instead wxApp and I've used wxInitializer and wxSocketBase::Initialize() to init. However it has never got to OnSocketEvent(). So I replaced wxEvtHandler with wxApp and it worked. But only on X platform.
question #1 - it's possible to use wxSocketEvent without wxApp and how?
question #2 - if I'd have to use wxApp, will it work if I compile/link it against wxBase?
