Cannot find -lSDL2main, -lSDL

I started following Lazyfoo’s SDL and got stuck at the installs.

Basically, I’m running a windows 64 machine and put SDL2.dll on both System32 (for 32 bits) and SysWOW64 (for 64) and then I created a folder called mingw_dev_lib where I put the folders for the 32 bits SDL.

But when I compile with the makefile, it gives me this error message:

mingw32-make.exe: *** [all] Error 1

Whereas if I put the 64bits folders on mingw_dev_lib it compiles with no problems, but then the exe doesn’t run.

For the tutorial, should I put the SDL2.dll 32 bits on SysWOW64? Along with 32 bits folders for mingw_dev_lib? And do I need to compile with the flag -m32?

Edit: I fixed it, nvm.

How did you fixed that?
