SFML Compilation with static libs Error. C++

Question

Trying to compile my silly hello-world SFML project for test. But getting strange error messages from linker. (When I compile with shared lib's - everything is OK.)

g++ -DSFML_STATIC -O2 -no-pie -fno-pie -o main main.cpp -L/home/uzzer/LIB/SFML-2.5.1/lib -lstdc++ -lc -lm -ldl -lX11 -lGL -lGLU -lsfml-system-s -lsfml-graphics-s -lsfml-window-s

Error messages:

What am I doing wrong / stupid?

Try g++ -DSFML_STATIC -O2 -no-pie -fno-pie -o main main.cpp -L/home/uzzer/LIB/SFML-2.5.1/lib -lsfml-system-s -lsfml-graphics-s -lsfml-window-s -lstdc++ -lc -lm -ldl -lX11 -lGL -lGLU. What happens? — Sean Francis N. Ballais

The order of libraries on the command line is important - this means that a library containing the definition of a function should appear after any source files or object files which use it. Please see here for more information. Also the comment of @SeanFrancisNBallais is exactly about that.

In your case you need to place the sfml-system-s library after all other SFML libraries, something like below:

 g++ <...other options...> -lsfml-graphics-s -lsfml-window-s -lsfml-system-s -lGLU -lGL -lX11 -ludev -lpthread

Also, from this line you can see that the GL library uses the X11 library (not vise versa) and so on. Some basic GCC libraries, such as stdc++ or m, aren't to be present on the command line - they are here by default.
