QUESTION

CMakeLists - How to include a directory of source and header files?

Asked 2021-Jul-09 at 16:35

I feel like this question has been asked a bunch of times, but none of the answers I have found seem to be working for me. I'm extremely new to CMake and C/C++ as I come from the world of Java, and am struggling to understand cmake and how it works.

Anyways, basically I have the folder structure below. This is an esp-idf project, so I don't know if that has anything to do with what I'm running into.

The ESP-IDF build system is built on top of CMake. This means you can use all the standard features of CMake in your files. However, the the ESP-IDF system predefines many functions, and makes many assumptions about the layout of your project, supposedly to make things "easier". Instead of reading CMake documentation, start by reading and understanding the ESP-IDF build system documentation:

https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/build-system.html

It looks to me like there is a particular layout expected for subcomponents, including the format of the CMakeLists.txt file. Specifically, move Metriful under a new directory called components, or add Metriful to EXTRA_COMPONENT_DIRS near the top of your root CMakeLists.txt

If Metriful is not written as an esp-idf component, this may not work. However, the document also describes how to link to "pure CMake" components, which will look something like this (at the end of your root CMakeLists.txt).

QUESTION

How to dynamically create ressource with attribute?

Asked 2020-Mar-31 at 11:00

Context

I'm trying to dynamically create and access multiple CoAP ressources on the same server. Basically what is would like is something like get coap://ip/ressource/* and get all the data of ressource/1 ressource/n

Linked subject

I found the following CoAP: Group similar resources under one

"what's left is that you create a /TIME/ resource (the slash at the end does matter) and announce it in .well-known/core as ;if="core.b"."

Problem

I don't know how i can create a ressource with specific attributes from client

Experiment with libcoap

coap-client -m put coap://ip/ressource;if="core.b" doesn't return error but attributes is not created (used copper)

That's entirely up to the server. Are you writing the server (if so, using which framework?) or just trying to make an existing server (if so, which?) behave as you like?
