/usr/bin/ld: cannot find : No such file or directory

Question

I'm following this SDL tutorial to try and make use of some SDL extension libraries. My code is identical to theirs but I am still unable to make the file which leads me to believe the problem is in my makefile which looks like this:

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)

That makefile worked fine for previous examples. The only thing that has changed in this example is line 5 where I added -lSDL2_image as per the tutorial. When I try make the file I get the following traceback:

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

Is there an error with my makefile? Have I not installed the library correctly?

Answer 1

The problem is this rogue comma:

SDL_LIB = -L/usr/local/lib -lSDL2 -Wl,-rpath=/usr/local/lib, -lSDL2_image
                                                           ^

causing the linker to look for libraries in a non-existent directory with an empty name, as well as /usr/local/lib. Removing the comma should fix it.
