Building a dynamic library using libmaix

[pauceano]

I am trying to build a dynamic library using libmaix but I cannot.
I want to build libZMQ library,

I copied the hello_world example in libmaix, I have put all sources in main/src and includes in main/include

I have added to /libmaix/examples/libzmq/main/CMakeLists.txt
list(APPEND ADD_DEFINITIONS -fPIC)
and register_component(SHARED)
I see in the logs that compile.cmake has activated to_dynamic_lib flag.
But, after compiling everything, it ends with the following error:
.....

seems not suport set main component as dynamic, you can create new component set to dynamic, and the so file will be in build dir.

This is a new feature request: Compile project to dynamic lib, I can support it later, but now you can resolve it by the upper method.

Thank you for your rapid answer.
Sorry, I do not understand how "create new component set to dynamic"
Can you please detail?

/libmaix/examples/libzmq/main 重命名这个文件夹（比如 libzmq）
再建一个 /libmaix/examples/libzmq/main
main 文件夹里搞一个 .c 再随便写个 main 函数
改 /libmaix/examples/libzmq/compile/priority 让 main 依赖 libzmq

Working, thanks.
