Title: Error when linking project on CSFML
Post by: DevilArx on April 14, 2017, 07:43:46 pm

When i compile a project, I get this error:

OS: Windows 7

C:\Users\DevilArx\Workspace\Roguelike-study>gcc *.o -L"lib/CSFML/lib" -lcsfml-window-2 -lcsfml-graphics-2 -lcsfml-system-2

main.o:main.c:(.text+0xed): undefined reference to `_imp__sfRenderWindow_destroy'
collect2.exe: error: ld returned 1 exit status

Tell me please how can I fix this?

Use the proper linking order. The graphics module depends on the window module so tje graphics module has to be linked before the window module.

After changing the order, the errors still remains

C:\Users\DevilArx\Workspace\Roguelike-study>gcc *.o -L"lib/CSFML/lib" -lcsfml-graphics-2 -lcsfml-window-2 -lcsfml-system-2

Your main object files need to be placed before linking libraries.
Just remember to use the "depends on"-rule: main.o depends on sfml-graphics depends on sfml-window depends on sfml-system
That gives you the linking order.
