System Workbench for STM32

Hello,

About the way to link a library through Eclipse, indeed:
- The library name should be prefixed by "lib" with the ".a suffix (like "libSTemWin522_CM4_OS_GCC.a")
- The Library should be linked through the project properties (C/C++ General > Paths and Symbols > Libraries). There you need to call the lib but without the prefix and suffix (just "STemWin522_CM4_OS_GCC" in our example).
The library path has to be provided through the "Library Paths" tab.

Can you tell us more about your errors (especially the first ones that are referenced through the console).
Did you add correctly all the include files? You still need to provide the EmWin header files (and there are a lot of them, not only the GUI.h file). And if they are placed in a specific "include" folder (not the provide "inc" subfolder of your project), you will have to add this path to the project properties ( C/C++ General > Paths and Symbols > Includes > GNU C ).
