Creating my own library

[leenowell]

Hi All,

I have a few projects on the go and have created a number of functions that are common to them all. I am looking to create a common library for them and then use this library in my other projects. I have searched around but can't find any instructions on how to create the library and then how to add it into an ESP32 project. I am using the VSCode IDE and extension so how to do it in that would be ideal but can do it outside of it if needed.

Many thanks in advance

Lee.

You can use EXTRA_COMPONENT_DIRS in CMakeLists.txt.

Here's an example.

Thanks very much for getting back to me. I think this would include the component source and header files directly rather than create a binary that I could link into my project (e.g. a ".o" or ".a")? Is there a way of linking a pre-built binary or maybe this is how the ESP setup works?

Many thanks

Lee.

Fantastic thanks very much for your help will give it a go.

or maybe this is how the ESP setup works?

It most commonly is. One reason is that you often want the library/component to be configurable via Kconfig/menuconfig; another one is support for different SoCs, which a pre-built library may not be able to offer easily.

Thanks for replying @MicroController. Very good points thanks very much.
