[SOLVED] Static linking in MS VS2019

[PawelSokolowski]

Hi everyone,

I have read all threads about static linking, and nothing works.
I have added preprocessor directive SFML_STATIC
I have such libs included :
sfml-graphics-s.lib;
sfml-window-s.lib;
sfml-system-s.lib;
sfml-network-s.lib;
sfml-audio-s.lib;
kernel32.lib;
user32.lib;
gdi32.lib;
winspool.lib;
comdlg32.lib;
advapi32.lib;
shell32.lib;
ole32.lib;
oleaut32.lib;
uuid.lib;
odbc32.lib;
odbccp32.lib;
winmm.lib;
%(AdditionalDependencies)

and still I have errors:

Funny thing is, that if I include libs without -s, there are no errors about libs, but there is one:
Build started...

Can anyone have a look and explain what is going on ?

Have you also added the path to the SFML headers (the include folder)?

[SOLVED]

Thank you for your response.
I have included headers, before I decided to go STATIC, everything worked just fine. Without headers it would not compile dynamically as well.

I have just located the problem.
Apparently static linking does not include by default some additional system libraries that are needed.
I had to add OPENGL32.LIB and FREETYPE.LIB.
Strangely dynamic linking worked without it.

[kojack]

When a static library like sfml-graphics-s.lib is built, the full linking process isn't performed. It takes the compiled obj files and bundles them together. The dependencies of sfml-graphics-s.lib (like opengl32.lib) aren't included.
So adding a static library to your project is like adding all of the cpp files, except the compiling bit is already done. The final link step to make the executable still needs to be told about the dependencies.

A dynamic library has complete working code in the dll, it had the full link process so its dependencies were used. Adding the dynamic library to your project doesn't require libraries like opengl32.lib unless you wanted to access it directly yourself.

[Hapax]

Ah, yes; I hadn't realised you had missed a couple of dependencies.
