c++ - 体系结构 x86_64 "_SDL_Init"的 undefined symbol

Question

每次我尝试编译一个使用 SDL 的程序时，它都会给我一个

"/Applications/Xcode.app/Contents/Developer/usr/bin/make" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf
"/Applications/Xcode.app/Contents/Developer/usr/bin/make"  -f nbproject/Makefile-Debug.mk dist/Debug/GNU-MacOSX/testProgram
mkdir -p dist/Debug/GNU-MacOSX
g++     -o dist/Debug/GNU-MacOSX/testProgram build/Debug/GNU-MacOSX/Window.o build/Debug/GNU-MacOSX/main.o -L/Library/Frameworks/SDL.framework -L/Library/Frameworks/SDL2.framework
Undefined symbols for architecture x86_64:
  "_SDL_Init", referenced from:
      Window::startWindow() in Window.o
  "_SDL_Quit", referenced from:
      Window::exitWindow(bool) in Window.o
  "_SDL_SetVideoMode", referenced from:
      Window::startWindow() in Window.o
  "_main", referenced from:
     implicit entry/start for main executable
     (maybe you meant: _SDL_main)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [dist/Debug/GNU-MacOSX/testProgramError 1
make[1]: *** [.build-conf] Error 2

我在 mac-OSX 上使用 netbeans(不是 Xcode，因为你不能制作跨平台应用程序)。

用-lSDL链接SDL库

或者尝试 `sdl-config -- cflags --libs`，至少，它类似于 SDL2(除了使用 sdl2-config)。
