I am trying to build a simple SFML example.

So no UPP on this.

SFML is under D:\sfml and build of static libs are under D:\sfml\build\lib

Assembly is uppdev with only D:\upp;D:\sfml as nests.

I have a main package named lab01 under D:\upp\lab0

I have added D:\sfml\build\lib as lib path under build methods.
I have added sfml-window-s, sfml-main, sfml-graphics-s under project/Package Organizer ( tried with and without a when option )
I have added PROTOTYPE under project/Main Package Configuration.

Compilation is OK but link fails as the -l option with libraries names is missing. Only -L is present:
Here is build log :

cd D:\upp\lab01

Exitcode: 1

There were errors. (0:01.12)

Also as a minor thing -Wl shows up twice one by itself and once in a --start-group .. --end-group contruct.
Thanks for help.

Did you add them as "Libraries" or as "Static Libraries"? Also keep in mind that linker order is relevant so make sure you're linking your libs in the correct order or symbols may not be found.

sfml-audio, sfml-graphics, sfml-window, sfml-system.

SFML documentation also says you must define SFML_STATIC if you're using the static version.

Those __declspec(dllimport) sections suggest you may not have that defined but I'm not sure. You'll have to look at your SFML documentation.
