mac，netbeans 6.8，C++，sdl，opengl：编译问题

我试图在Snow Leopard 64位下正确编译使用netbeans 6.8的C++ opengl + sdl应用程序。mac，netbeans 6.8，C++，sdl，opengl：编译问题

我有使用macports安装libSDL 1.2.14。

，我尝试编译脚本如下：

在NetBeans项目的属性我配置如下：

C++编译器：添加/usr/X11/include和/opt/local/include到包括目录。链接：我添加了以下库：

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

现在......我才列入SDL_main.h和libSDLMain.a到我得到一个错误unknown reference to _main

那么这个项目我读到这里：http://www.libsdl.org/faq.php?action=listentries&category=7#55

我需要包含SDL_Main.h并将libSDLMain.so链接到我的项目。

这样做后，项目仍然不会编译。这是Netbeans输出：

您是否想出了解决方案？我有一个链接错误，说没有找到'_objc_msgSend_fixup'。 – ashen 2011-02-25 12:28:10

你为什么不尝试使用pkg配置为： “pkg配置--cflags --libs SDL”（这些suposed是口音，但那些从答案删除）将输出或者做类似的事情： 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'

（请替换''）不确定ilut命名约定。您可能需要也可能不需要在最后添加一个框架OpenGL。（对不起，对于最近的答案= p）
