I just updated ZeroBrane to v .40 Whenever I try to run a Corona project from within the IDE, I get the following: 2014-03-01 12:16:46.272 Corona Simulator[6274:507] Copyright (C) 2009-2014 C o r o n a L a b s I n c . 2014-03-01 12:16:46.273 Corona Simulator[6274:507] Version: 3.0.0 2014-03-01 12:16:46.273 Corona Simulator[6274:507] Build: 2014.2179 dyld: lazy symbol binding failed: Symbol not found: _gliCreateContextWithShared Referenced from: /System/Library/Frameworks/OpenGL.framework/Resources/GLEngine.bundle/GLEngine Expected in: flat namespace dyld: Symbol not found: _gliCreateContextWithShared Referenced from: /System/Library/Frameworks/OpenGL.framework/Resources/GLEngine.bundle/GLEngine Expected in: flat namespace Program completed in 20.12 seconds (pid: 6274). If I run the same project directly from Corona, it executes. I've tried this with a couple of different projects, with the same results. It looks like I'm not the only person having this problem: http://forums.coronalabs.com/topic/44898-cannot-start-simulator-crash-suddenly-today-dyld-lazy-symbol-binding-failed/ Has anyone found any solutions to this? Thanks, -m.
