Crashes on Mac OSX

Hi,
I just compiled my game for Mac OSX using Irrlicht 1.7.2.
Many people report crashes and can't start the game. It works fine for me on an old Macbook. Tested it on a Macbook Air, doesn't work.
Here are the typical crash reports they are getting:
Model: Macmini2,1, BootROM MM21.009A.B00, 2 processors, Intel Core 2 Duo, 2 GHz, 2 GB, SMC 1.19f2
Graphics: Intel GMA 950, GMA 950, Built-In, spdisplays_integrated_vram
OS Version: Mac OS X 10.6.8 (10K549)

[0] Irrlicht Engine version 1.7.2

I don't have a newer OSX system, so I cannot test those cases. But it seems that some OpenGL libs are simply missing here.

I believe you are missing the Cocoa framework, or maybe Carbon. You'll also need the IOKit framework for part of Irrlicht, but given that you're doing lazy linking (which is new to me, actually), you may not run into that requirement unless you support joysticks. Those are the three required frameworks for Irrlicht that I've found (via experimentation).

Here is what I'm linking against:
-lGL -lXxf86vm -lobjc -framework cocoa -framework carbon -framework opengl -framework IOKit
I do support joysticks, is that a problem?

Are they actually case-insensitive like that? I would think the lowercase "cocoa", "carbon" and "opengl" could mess up at least most systems. IOKit is capitalized correctly, as is objc. And no, I don't believe it's a problem, I was simply saying that (I think) IOKit is only necessary for joystick stuff; so in your case, it's crucial that you do link with it.
If capitalizing fixes it, I dunno; I'm using CMake so it kinda happens magically, which I like.

So what case should it be? Would you mind pasting me the CMake lines where the linking is done?

CMake is complicated and I'm rather new at it, but I think this is the relevant linking bit that you need:
Code: Select all
-lIrrlicht -framework AGL -framework OpenGL -framework Carbon -framework Cocoa -framework IOKit
Here is my main CMakeLists.txt file, in case you or someone else reading this wants to use CMake. It seems to work well.
Code: Select all
cmake_minimum_required(VERSION 2.8)
PROJECT(ArcaneTrinity)
SET(CMAKE_MODULE_PATH "${PROJECT_SOURCE_DIR}/cmake" ${CMAKE_MODULE_PATH})
FIND_PACKAGE(OpenGL)
FIND_PACKAGE(Irrlicht)
FIND_PACKAGE(MsgPack)
IF (APPLE)
FIND_LIBRARY(CARBON_LIBRARY Carbon)
FIND_LIBRARY(COCOA_LIBRARY Cocoa)
FIND_LIBRARY(IOKIT_LIBRARY IOKit)
SET(OSX_LIBRARIES ${CARBON_LIBRARY} ${COCOA_LIBRARY} ${IOKIT_LIBRARY})
SET(CMAKE_LIBRARY_PATH /opt/local/lib ${CMAKE_LIBRARY_PATH})
ENDIF (APPLE)
INCLUDE_DIRECTORIES(${IRRLICHT_INCLUDE_DIR} ${MSGPACK_INCLUDE_DIR}
${OPENGL_INCLUDE_DIR})
SET(EXECUTABLE_OUTPUT_PATH ${PROJECT_BINARY_DIR}/bin)
ADD_SUBDIRECTORY(src)

I can NOT for the life of me seem to get cmake to work with Irrlicht on OSX.... Complains about missing frameworks, etc.. Does anyone have a sample tar.gz (HelloWorld for example) that works that I can expand on? Thanks!
P.S. A Cmake config that compiles Irrlicht would be awesome too, but I'm not getting my hopes up.
P.S.S. I'm new to Cmake as well, but it seems as though your example above is missing something. You are finding the libraries, but I don't see where you are using them - or am I missing something?

Hi oeginc, let's not hijack this thread. Hopefully the arguments I provided earlier will help MolokoTheMole; as for CMake, since you're interested, read
this thread. I just made a Github project that should help you.
