This is an experimental Docker-based version of MXE.

MXE is a nice cross compiling environment with many free libraries. See their site for more.

The only dependency here is Docker itself, everything else will automatically happen inside the Docker container.

1. Clone this repo or download a tarball:

   git clone https://github.com/lbguilherme/dmxe
   cd dmxe

2. Prepare the MXE image. This will fetch the lastest Debian image and install all dependencies. Then it will clone the mxe repo inside it.

   ./dmxe prepare

3. Make the libraries you need. This will launch the container and invoke make there with whatever you pass here:

   ./dmxe make gcc

4. Create your first code to compile with MXE. For example:

   // main.c
   #include <windows.h>
   
   int main() {
   	MessageBoxA(0, "Hello World from Docker MXE!", "MXE", MB_OK);
   	return 0;
   }

5. Run the image you have just built:

   ./dmxe run

   You will be presented with a shell where you can access your current directory:

   mxe@default:~$

6. Simply compile your file and exit. i686-w64-mingw32.static-gcc here is the cross compiler for the default target:

   mxe@default:~$ i686-w64-mingw32.static-gcc main.c -o main.exe
   mxe@default:~$ exit

7. Take a look on the file you have produced:

   file main.exe
   # main.exe: PE32 executable (console) Intel 80386, for MS Windows

8. Run it! Wine is your friend.

   wine main.exe
