System Workbench for STM32

Dear Shreeyak
Here is the way I am using to add folders/files into my project’s folder :

• Using Windows Explorer, I copied a folder containing several files;
• I pasted it in my project’s folder (in the Project Explorer window of SW4STM32);
• Right-click to open the build properties dialog for this new folder (folder >> Properties >> C/C++ Build) and uncheck the Exclude resource from build checkbox;

Using these steps, the new files are properly compiled.
Note : the new files are part of the project. The new folder is not seen as a library.
The new code will be included in the final object code, as the linked does not know how to choose what is really needed.

I made trials but I cannot reproduce the issue you faced, so feel free to give more details :

• How do you copy the files into your project’s folder?
• How do you add it as a source folder?
