I can't execute this code： ./build_all.sh

Hello, I have a problem that can't be solved. Can you help me?.
When I tried to run your banana classifier with a terminal, I met the following tips:

Macbook-Pro:~ fcx$ cd ~/opencv-2.4.9/samples/c

Macbook-Pro:c fcx$ chmod +x build_all.sh

Macbook-Pro:c fcx$ ./build_all.sh

Did you install OpenCV with libtbb before? The clang: error: argument to '-l' is missing sounds to me like the build script is trying to pass the path of a dependency (libtbb?) to clang with -l <dependency> but it's missing.
