Question

I am trying to compile the simple C example from this tutorial on Ubuntu using GCC. What do I have to use as arguments for GCC to include the needed libraries for #include <libappindicator/app-indicator.h>?

Answer 1

If you used apt-get, Synaptic Package Manager, etc. to get the appindicator library (vs. building it from source), did you only install the libappindicator1 package or did you also install libappindicator-dev to get the libappindicator header files? Linux packages very often have split the runtime libraries from the compile-time headers. That way people who only need the libraries to satisfy a dynamic link don’t have to install unneeded headers. But since you’re doing development you need those headers and therefore need the libappindicator-dev package as well.
