Graphics / Integrating with wxWidgets issues

« on: March 08, 2009, 09:48:54 pm »

i'm attempting to compile a _slightly_ modified wxwidgets-SFML example, and it compiles, but the SFML canvas is invisible... I modified it to get the "quit" menu bar function working under OS X 10.5, but that's it. it was invisible before I modified it, as well, so that's not the issue.

okay, now when I put the files in there, the application stalls for a bit and crashes.  

do you think we could talk about this on an instant messenger so I could get this problem figured out a bit faster? i've listed my contact details below:

General / [C++/OSX] libraries don't link properly

Never has this been done automatically.

but when I compile the basic included SFML template, it DOES do it automatically.  :?

« on: January 03, 2009, 01:59:40 am »

The debugger asks for the frameworks to be copied in appname.app/Contents/Frameworks. Make sure this is where you put them.

Otherwise, for general development with SFML, the frameworks must be copied in /Library/Frameworks.

right, but usually the frameworks are automatically put in that folder, and now, for some reason, they are not.

I am attempting to build a friend's SFML game on the Mac OS X platform, and am having a bit of trouble. I start a new Xcode project from the Xcode templates included with the SFML download. It builds and runs fine. But then, when I change the main.cpp into the one for my friend's game, the built application will not fully launch. GDB tells me (see bottom of post) the application cannot load the SFML frameworks from the Frameworks directory of the app bundle, and sure enough, no Frameworks (or Resources) directories have been created, even though Xcode says it built properly. What would be the cause of this? I'm not positive if my friend wants me to share the source, but I'm just wondering if there's anything that can be put in main.cpp that'd disable the proper linking of the libraries?

And, furthermore, when I put the libraries manually into the Frameworks folder, it still doesn't load. What's up with that?

Graphics / Failed to load image

« on: January 02, 2009, 02:00:12 am »

use cocoa's bundle-handling code to load your images from the bundle's resource directory.

Alright, I'll need a bit more help than that, since I'm not a cocoa programmer. How exactly would I go about doing this?
