Static-linking of SDL2 libraries

Question

I am using Windows 7, Code::Blocks and MinGW. I have little to no experience when it comes to compiling/building anything, especially when Code::Blocks doesn't use makefiles.

I downloaded SDL2-devel-2.0.0-mingw.tar.gz (SDL Development Libraries) from http://www.libsdl.org/tmp/download-2.0.php, and I'd like to create a standalone executable using SDL2 libraries, but so far I've always had to bundle the SDL2.dll file with the executable to make it work.

I've heard that I can not static-link dynamic libraries, so my only option seems to be doing something with the source files using the file SDL2-2.0.0.tar.gz (Source Code) from the link I mentioned above. However, I do not know what I should do with those.

What I managed to try with the source files is importing the Visual Studio project to Code::Blocks and building it, but it tells me "sdl-config No such file or directory" (I do not know what triggered that). I'm also not sure if building merely gives me an executable, with which I do not know what I can do to link it to my own executable.

A fool proof idiot's step by step guide would be the best bet to solve this case.

EDIT:

I managed to compile the SDL libraries with the guide Jonas provided, and got a libSDL2.a file.

At first I only added the path of libSDL2.a to "Link libraries:" -section of Code::Blocks, but I got a bunch of errors such as "SDL_Init() not declared in this scope".

In addition to the libSDL2.a path, I also added the path of SDL2-2.0.0\include to the Compiler's search directory as well as the path of SDL2-2.0.0\build.libs to the Linker's search directory. I also wrote this to my test file: #include "SDL.h". My test file now looks like this:

#include "SDL.h"

int main( int argc, char* args[] ) {
    //Start SDL
    SDL_Init( SDL_INIT_EVERYTHING );
    //Quit SDL
    SDL_Quit();
    return 0;
}

It appears it did fix the declaration problem, but now Code::Blocks opened a SDL_mmjoystick.c file and gave me even more errors: "undefined reference to 'waveInClose@4'", "undefined reference to 'waveOutClose@4'", "undefined reference to 'joyGetNumDevs@0'" and tons of other ones.

Here's a screenshot of what's happening, note the different color of #include texts, I'm not sure why that happens: http://gyazo.com/00656a9c1e57a2bd0db1414fa7d68ced.png

I am not sure how to correctly take this library into use. Any help in this case, or should I make another question for it?

EDIT:

I added -lSDL2 to the linker options and deleted the other parameters. Now it builds fine:

mingw32-g++.exe -Wall -fexceptions  -g    -IC:\Users\User\Desktop\SDL2-2.0.0\include  -c "C:\Users\User\Desktop\CppProjects\SDL project\main.cpp" -o obj\Debug\main.o
mingw32-g++.exe -Wall -fexceptions  -g    -IC:\Users\User\Desktop\SDL2-2.0.0\include  -c "C:\Users\User\Desktop\CppProjects\SDL project\thetestfile.cpp" -o obj\Debug\thetestfile.o
mingw32-g++.exe -LC:\Users\User\Desktop\SDL2-2.0.0\build\.libs  -o "bin\Debug\SDL project.exe" obj\Debug\main.o obj\Debug\thetestfile.o   -lSDL2  ..\..\SDL2-2.0.0\build\.libs\libSDL2.a C:\Users\User\Desktop\SDL2-2.0.0\build\.libs\libSDL2.a  -mwindows
Output size is 945.80 KB
Process terminated with status 0 (0 minutes, 1 seconds)
0 errors, 0 warnings (0 minutes, 1 seconds)

But when I try to run it, it says my computer lacks SDL2.dll, while the whole point was to static-link.

So currently I have the path to build/.libs in my Link libraries -settings, -lSDL2 in the Other linker options, and for search directories I have the path to SDL2-2.0.0/include for the compiler and SDL2-2.0.0/build/.libs for the linker.

In the build/.libs directory I can also see libSDL2.a, libSDL2.dll.a, libSDL2.la and libSDL2.lai files, which I don't know what they are.

It's not necessary to recompile the library, SDL2 is given with static-link library named "libSDL2.a" on the folder "SDL2-2.0.0\i686-w64-mingw32\lib\".

Just be sure to add these options to the linker :

"-lmingw32 -lSDL2main -lSDL2 -mwindows -lm -ldinput8 -ldxguid -ldxerr8 -luser32 -lgdi32 -lwinmm -limm32 -lole32 -loleaut32 -lshell32 -lversion -luuid -static-libgcc"

on Code:Blocks at "Project / Build Options... / Linket settings / Other linker options"

These options allow you to link with what SDL2.dll was using.

You can retreive them on the file "SDL2-2.0.0\i686-w64-mingw32\bin\sdl2-config"

The magical trick is to delete or rename the file "libSDL2.dll.a" on the folder "SDL2-2.0.0\i686-w64-mingw32\lib\". I added a "-" before to keep it in case I need it.

I don't know why this librairy overcomes the other and a clue would be appreciated.

I tried with Code::Blocks 12.11 MinGW32 and it worked.

If you run with some projects that use dynamic-link and some other which use static-link, you will have to keep your librairies in two different folders knowing that "libSDL2main.a" will be in those two.

Sorry for my writing, I'm not used to write in english.
