/ usr/bin/ld:找不到:没有这样的文件或目录

我正在按照这个 SDL教程尝试使用一些SDL扩展库.我的代码与他们的代码相同,但我仍然无法找到make导致我相信问题出现在我的文件中的文件makefile如下:

CXX = g++
# Update these paths to match your installation
# You may also need to update the linker option rpath, which sets where to look for
# the SDL2 libraries at runtime to match your install
SDL_LIB = -L/usr/local/lib -lSDL2 -Wl,-rpath=/usr/local/lib, -lSDL2_image
SDL_INCLUDE = -I/usr/local/include
# You may need to change -std=c++11 to -std=c++0x if your compiler is a bit older
CXXFLAGS = -Wall -c -std=c++11 $(SDL_INCLUDE)
LDFLAGS = $(SDL_LIB)
EXE = SDL_Lesson3

all: $(EXE)

$(EXE): main.o
    $(CXX) $< $(LDFLAGS) -o $@

main.o: main.cpp
    $(CXX) $(CXXFLAGS) $< -o $@

clean:
    rm *.o && rm $(EXE)

这makefile对以前的例子很好.在这个例子中唯一改变的是第5行,我-lSDL2_image根据教程添加了.当我尝试make该文件时,我得到以下回溯:

rony@comet:~/Documents/cpp/helloworld/lesson3$ make
g++ main.o -L/usr/local/lib -lSDL2 -Wl,-rpath=/usr/local/lib, -lSDL2_image -o SDL_Lesson3
/usr/bin/ld: cannot find : No such file or directory
collect2: error: ld returned 1 exit status
make: *** [SDL_Lesson3] Error 1

我的makefile有错误吗？我没有正确安装库吗？
