That's a compilation error, not a linker problem. You need to tell the compiler about the function with a prototype:
Declaring the function does fix the compiler problem. However, I do get a linker error once I compile that:
```bash $ g++ ../build/libshared-api.so main.cpp /usr/bin/ld: /tmp/ccNMKxEE.o: in function `main': main.cpp:(.text+0x2a): undefined reference to `foo()' collect2: error: ld returned 1 exit status ```
