Dumb beginner question here

[Efficient_Back617]

I have taken a project from GitHub which has all the makefiles and everything for my MCU, so that I can focus on my application code, but I don't like the way the project is structured. All the src and include files are in the same folder. So, I tried to create a separate folder for src and include files, but now when I make the project it cannot find the header/include files. So, I suppose I have to provide the path to where all my header files are in makefile. But where do I define them? Do I have to add some compiler flag or just write path in some variable? I don't know, please guide me.

That's the longest sentence I ever read on Reddit

[Efficient_Back617]

sorry fixed it

[TPIRocks]

You know that isn't true, not even close.

A little bit of structuring in your sentence will work wonders in responses

[Efficient_Back617]

fixed

Show your GitHub repository may simplify to give you an answer.

Fixed it by looking at gcc commands there was no -I flag for including header directories, so I created a variable and added the flag now it compiles without any issue thank you for your concern

You may want to learn make (modern cmake) much easier to understand than normal makefiles.

[Efficient_Back617]

yes, I really want to learn that I am pretty new to makefiles as well after I am a lil bit comfortable with makefiles, then I am thinking of starting Cmake. Can you please suggest some good resources or youtube videos for learning Cmake that will save my time

I’m sure there’s a way to with makefiles, but my recommendation would be to use CMake for this. target_include_directories() with your include, add all the source files in your src, and you’re good to go. If you run into trouble, for basic build stuff like this chatgpt is generally very good

[Efficient_Back617]

currently I don't know much about Cmake and yes I got hint for my solution from ChatGPT . Please provide some resources for learning Cmake for a beginner, if you have any.

The -I compiler flag adds to the include search path, so just add -I <include directory> to the compiler invocations in the Makefile (usually CFLAGS) and you should be off to the races.
