Anyone? X.X

The error message is clear: SDL can't be found, make sure Mingw knows where to find it.
As for patches:
http://jungels.net/articles/diff-patch-ten-minutes.html

And how exactly would I specify the path in Mingw?

I'm pretty sure it's necessary to compile SDL (and SDL_net if you need that too). The wiki article needs an update anyway...

Let's say you extracted "SDL-1.2.15.tar.gz" and "SDL_net-1.2.8.tar.gz" into their own directories under your user folder in mingw:

- Navigate to ~/SDL-1.2.15 and compile SDL:
./configure
make
make install

- Navigate to ~/SDL_net-1.2.8 and compile SDL_net:
./configure
make
make install

- Add the libraries to your PATH variable:
PATH=$PATH:~/SDL-1.2.15
PATH=$PATH:~/SDL_net-1.2.8

You don't need to compile SDL you just need to place the mingw package correctly. Wiki article is writing something wrong in regard to this.

I've tried following this guide in that regard, but it still complains it cannot find SDL.
How would I "place" the SDL package? (again, sorry for my illiteracy)

You should uncompress SDL-devel into your home directory inside msys, run msys and type 'make native' to install it.

That fixed the problem, thanks. Now I tried to add the MUNT patch to DosBox (with the help of the guide provided by bloodbat), and it complains about missing files...

1midi.cpp:106:23: fatal error: midi_mt32.h: No such file or directory

I have no idea where to get that file since it didn't come with the .diff file.

The .diff file is only the changes to the DOSBox source, you also need the libs and headers for the munt emulator where the compile environment can find them.

Got the MUNT sourcefiles but not sure where should I put them so that Mingw can find them...

Again you first need to compile munt. With cmake in msys/mingw

Compiling with cmake gives me this:

You need to configure cmake to point to your correct compiler (GCC) it defaults to Borland...

http://www.cmake.org/Wiki/CMake_FAQ#How_do_I_ … ent_compiler.3F

and when you have this sorted out, make sure you only cmake the lib and nothing else, because the other stuff wants glib2 (and that brings a whole other hell to compiling life 😀)

Would that correct compiler be under Mingw? I'm not sure where I'm supposed to find it. Also have no idea what that generator would stand for ^^;

If using their automated installer with default paths or following one of their guides it lives in c:\mingw\bin\g++.exe (why you are trying to compile something without knowing at least where your compiler is...is beyond me).
As for the generator you probably want CMakeLists.txt and to read this http://www.cmake.org/cmake/help/cmake_tutorial.html

Okay, somehow I got it work, got the makefile and I tried to make it in MinGW, yet it crashes when I do so.

Sorry for the double post, copied the MUNT files in dosbox/src/gui/ (where it was looking for "midi_mt32.h" ) and it seemed to work, up to this point:

You need to cmake the mt32emu lib and place it in the lib folder...
