I can think of two things:
1. You're using a triple that is different from your gcc name:
You should use the target as "arm-linux-gnueabihf".
2. You're not including the GCC headers or libraries.
You need to find where GCC keeps its libraries (normally
/usr/lib/gcc/arm-linux-gnueabihf) and headers (if necessary).
In your case, just adding -L"where your gcc libs are" should be enough.
