The linker thinks "D:\CodeBlocks\MinGW\lib" is a library, but it is not. It is a folder.
You have to add the folder where the libraries are in
Project->Build options->Search directories->Linker
and the libraries only with name in 
Project->Build options->Search directories->Linker settings->Link libraries

Do not add any library settings in "Project->Build options->Search directories->Linker settings->Other linker options"
or if you do keep atention that "-L" is for folders and "-l" is for libraries

in the line posted by stahta01:
Code: [Select]
mingw32-g++.exe -LG:\SDL\SDL-devel-1.2.15-mingw32\SDL-1.2.15\lib -LG:\SDK\Lib -LD:\CodeBlocks\MinGW\lib -o bin\Debug\WindowMain_0.exe obj\Debug\WindowMain_0.o -lmingw32 -lSDLmain -lSDL D:\CodeBlocks\MinGW\libYou can see that
Code: [Select]
D:\CodeBlocks\MinGW\lib has no option prefix ("-L" or "-l") so you have posted this in one place where you should not...

[Edit:] ok, someone was quicker, but i post it anyway

Yes Yes. Of course, I deleted it. Thank! But I get an undefined reference error to `GetStockObject @ 4 '|. I experimented with the settings for about half an hour, and did not succeed in compiling.

I am still carefully reading the answers, I have not seen the latter, and I will try.

Go to this page: https://docs.microsoft.com/en-us/windows/win32/api/wingdi/nf-wingdi-getstockobject
Scroll to the bottom, read the "Requirements", add the required libraries to your linker settings.

This should be just gdi32!
