The project compiles without any issues now. Try it and see if it works out.

Do you have any idea how can I resolve this problem? Thank you.
Have you configured your BSP when you created it using Eclipse.? If not, then select the uart BSP top most project and right-click it. From the menu, look for NIOS II -> BSP Editor.
This will open up the BSP editor . Select the "Settings" option in the left pane. Here you need to make the following changes.
Select/Enable only the following 4 options :
Uncheck all other options. Click "Generate" and then Exit. Now, go to Eclipse and build the BSP and application again. This time it should compile without any errors.
I've included the same project with the software built in this ZIP file. You can have a look at it.
