mac，netbeans 6.8，C++，sdl，opengl：編譯問題

我試圖在Snow Leopard 64位下正確編譯使用netbeans 6.8的C++ opengl + sdl應用程序。mac，netbeans 6.8，C++，sdl，opengl：編譯問題

我有使用macports安裝libSDL 1.2.14。

，我嘗試編譯腳本如下：

#ifdef WIN32 
#define WIN32_LEAN_AND_MEAN

#endif 
#if defined(__APPLE__) && defined(__MACH__) 
#include <OpenGL/gl.h> // Header File For The OpenGL32 Library

#else 
#include <GL/gl.h> // Header File For The OpenGL32 Library 
#include <GL/glu.h> // Header File For The GLu32 Library 
#endif 
#include "sdl/SDL.h" 
#include <stdio.h>

#include "SDL/SDL_main.h"

在NetBeans項目的屬性我配置如下：

C++編譯器：添加/usr/X11/include和/opt/local/include到包括目錄。鏈接：我添加了以下庫：

/usr/X11/lib/libGL.dylib 
/usr/X11/lib/libGLU.dylib 
/opt/local/lib/libSDL.dylib 
/opt/local/lib/libSDLmain.a

現在......我才列入SDL_main.h和libSDLMain.a到我得到一個錯誤unknown reference to _main

那麼這個項目我讀到這裏：http://www.libsdl.org/faq.php?action=listentries&category=7#55

我需要包含SDL_Main.h並將libSDLMain.so鏈接到我的項目。

這樣做後，項目仍然不會編譯。這是Netbeans輸出：

您是否想出瞭解決方案？我有一個鏈接錯誤，說沒有找到'_objc_msgSend_fixup'。 – ashen 2011-02-25 12:28:10

你爲什麼不嘗試使用pkg配置爲：「pkg配置--cflags --libs SDL」（這些suposed是口音，但那些從答案刪除）將輸出或者做類似的事情： g ++ -o dist/Debug/GNU-MacOSX/opengl2 build/Debug/GNU-MacOSX/main.o'pkg-config --cflags --libs ilut''pkg-config --cflags --libs glu''pkg-config --cflags --libs sdl'

（請替換''）不確定ilut命名約定。您可能需要也可能不需要在最後添加一個框架OpenGL。（對不起，對於最近的答案= p）
