How to link library (.c and .h file) in CubeIDE?

[HPham.1590]

Hello, I'm new in STM32CubeIDE.

I want to create my library to use in my C/C++ project.

My library includes 2 files (.c and .h) but I don't know how to linking them in CubeIDE.

Anyone can help me?

Many thanks,

Hieu

Drag them into the Core/Src and Core/Inc (or Src and Inc) folders within your project. Add an #include statement for the header and use them in whatever file you need.

Thanks for your reply, but when i using CubeIDE, I added these file to locations as your refer but when I call function in this lib from other file, it still jump to .h file, not .c file.

Here is my simple .h file

#ifndef __GETCONFIG_H__
#define __GETCONFIG_H__
void SimJSON();
void GetConfig();
#endif

and .c file

#include "GetConfig.h"
#include "cJSON.h"
void SimJSON()
{
 
}
void GetCongif()
{
	SimJSON();
}

Not sure what you mean. Your .h file doesn't have any code, just definitions. The processor can't jump there.

In cubeide you don't need to register source files for compiler. There are directories under project root, named source folders, that you can put compilable files into. just copy paste your files in a source directory and you are good to go. you can later exclude files from compile through project options.​

but I dont know how to link these file. My function define in .h but written in .c file

A .h plus .c file is just source code, not a library that needs extra consideration for linking. If you follow the above instructions, you should see the .c file being compiled in the CDT Console Window.

Are you getting errors? What exactly?

[dbgarasiya]

just follow given instructions

[HPham.1590]

Well, that's my mistake. It's still linking but I tried to call this C lib in C++ file.

Sorry,

Hieu

Hello!

I try to link an exisiting library (.h and .cpp files) to a new project but the compilator dont see it

I'v drag the library folder into my project and selected "link files and create virtual folders"

And added de dependancies in the following entries:

In "Linked ressources" in "Path Variable"

In "Path and symbols" in "Include", "Library Path" and "Source Location"

in "Preprocessor Include Path Macros ..." in "CDT User Settings"

I'v put the path to the library folder where I thought it was necesary and after i'v put it everywhere I could >.<

There is no weird characters or spaces in the full path of the project or library.

i'v also tryed to put the linkes to the files in core/src and core/inc or in Middlewares but same issue.

I realy need the files to be linked and not in copie because they are used in the windows client and for the two core projects.

Did I missed or do something wrong ?

Thank you for your help !

Include paths are be in project properties -> C/C++ Build -> Settings -> Tool Settings -> MCU G++ Compiler -> Include paths. If that doesn't fix it, make a new thread and show a screenshot of your include paths.

Hello, thank you for your answer !

But the path was already there...

I'v created a new topic on the forum

Yes this works ...

Include paths are be in project properties -> C/C++ Build -> Settings -> Tool Settings -> MCU G++ Compiler -> Include paths.
