Hi Yf,
Just look at your System.map and you will see that all those main() became
<program>_main.
It isn't possible to have a unique main() symbol, otherwise we will have a
duplicated symbol, also even if the compiler accepted that, how could NuttX
know you want to call the main from Hello instead of the main from Alarm?

This is not true in the kernel build mode. All applications run at
exactly the same virtual address and the entry point is main() for all
of them. In the kernel build, all applications are loadable modules.
None of the symbols in the loadable modules will appear in System.map
since each application module is separately compiled and linked.
