I am porting a 3rd-party software to Genode framework. I follow this tutorial(https://genode.org/documentation/developer-resources/porting). When I execute the run command, the compilation process is complete, but there's a problem occurred when linking: "libc.lib.so: undefined reference to `Libc::Component::construct(Libc::Env&)' collect2: error: ld returned 1 exit status I have no idea how to fix this problem, can anyone give me some help?

If your ported application is a standard POSIX/Libc application it will come with the famous main() routine. In Genode, we apply a different execution model which calls construction functions for components. But, we also provide a library for backwards compatibility, which you may use by adding the following to your target.mk file.

LIBS += posix
