where is the main start point

[Guangyi-Z]

I don't know whether it's the right place to ask this question:

where is the DECLARE_ACTOR_MAIN and ACTOR_FUNCTION? I have read through the source code but not found any clues about them, i.e., where is the common main() start point of C program in the example?

Hi,

I was looking for a lightweight actor oriented C lib (to be used in embedded systems with small memory and OS) and this one seems to be quite promising.
However, I was not able to compile the examples it because the same error reported by JanFan.

I followed the instructions and that's the error messages I found:

There are quite a few undefined types/macros such as: ACTOR_FUNCTION, actor_main.

I executed a recursive 'grep' into the entire source code and those definitions are definitely not there.
Perhaps there is a missing file ....
