== Compiling Libraries==
When using this method, you will usually need to distribute some DLLs to make your builds work. These are normally located in the ''bin'' folder where MinGW packages were installed (e.g. /usr/i586-mingw32msvc/bin or /usr/i686-w64-mingw32/bin).
+
By compiling all the libraries yourself, the final executable will not need any DLLs to run.

Since figuring out all the right commands to cross compile the libraries can be difficult, here is a script that has all the right commands already: [https://raw.githubusercontent.com/The-Powder-Toy/buildserver-snapshot/master/provisioning-files/cross-libs/cross-libs.sh cross-libs.sh]
  
Some of the required libraries can be found here:

Running the script without arguments provides usage instructions. Start by changing the variables at the start of the script to match your MinGW installation. The default values are:<br />

MINGW_BIN_PREFIX="i686-w64-mingw32-" 
 +
MINGW_INSTALL_DIR="/usr/i686-w64-mingw32"

If you have problems with initial libraries lookup, it is useful to check config.log for obvious failures.
These DLLs will need to be distributed with your builds so they work. Or if you're lazy you can just  post the URLs and tell everyone else to download them.

ATTENTION: This guide is outdated as of 2021. Please use this guide for building any recent version of the game: Building TPT with Meson

This is for Linux users to cross-compile to Windows 32-bit.

BEFORE WE START, PLEASE MAKE SURE YOU CAN COMPILE FOR LINUX FIRST!

Packages

First, install the basic packages needed for cross compiling.

Search for the following in your package manager: mingw32 mingw32-binutils mingw32-runtime

Ubuntu Users Run the following in a terminal:
sudo apt-get install mingw-w64

In older recent versions of Ubuntu, try:
sudo apt-get install mingw32 mingw32-binutils mingw32-runtime

Debian Users In a terminal:
su -c "apt-get install mingw32 mingw32-binutils mingw32-runtime"

Arch Users In your Terminal:
su -c 'pacman -S mingw32-{gcc,binutils,runtime}'

After you have installed these, there should be /usr/XXXX-mingw32msvc , XXXX may be i486, i586, i686 or something else. Anywhere further in this tutorial i will refer to the folder name as $MINGW , for instance /usr/$MINGW/lib You could actually set such an environment variable for simplicity.

You will also need to enable the posix threading model, instead of Windows. Run each of these manually and select the -posix variants:
sudo update-alternatives --config i686-w64-mingw32-gcc
sudo update-alternatives --config i686-w64-mingw32-g++
sudo update-alternatives --config x86_64-w64-mingw32-gcc
sudo update-alternatives --config x86_64-w64-mingw32-g++

You will have to include libgcc_s_sjlj-1.dll with your .exe.

Libraries

Next, Powder Toy needs a couple of libraries. There are three ways to get them:

  • Package repositories. This is sometimes the easiest way, but not all distributions have MinGW versions of all the required libraries in their package repositories
  • Download and extract precompiled libraries. However, you usually cannot statically compile when using this way
  • Compile from source. This would normally be difficult, but there is a script available to help you. You'll need to use this method if you don't want to distribute DLL files with your executables.

The libraries needed are:

  • SDL2
  • bzip2
  • Lua (optional - if you don't want to use it, use --nolua option)
  • FFTW (optional - if you don't want to use it, use --nofft option)
  • curl (optional - if you don't want to use it, use --nohttp option)

Compiling Libraries

By compiling all the libraries yourself, the final executable will not need any DLLs to run.

Since figuring out all the right commands to cross compile the libraries can be difficult, here is a script that has all the right commands already: cross-libs.sh

Running the script without arguments provides usage instructions. Start by changing the variables at the start of the script to match your MinGW installation. The default values are:

HOST="i686-w64-mingw32"  
MINGW_BIN_PREFIX="i686-w64-mingw32-"  
MINGW_INSTALL_DIR="/usr/i686-w64-mingw32" 

On older versions of Debian/Ubuntu, you might change this to:

HOST="i586-mingw32msvc"
MINGW_BIN_PREFIX="i586-mingw32msvc-"
MINGW_INSTALL_DIR="/usr/i586-mingw32msvc"

Please note, if you installed MingW for older recent versions of Ubuntu as shown in step 1, you MUST change these variables.

Now compile and install the libraries as follows (they will automatically be downloaded. Simply open a terminal, and enter the following commands):

./cross-libs.sh make bzip2 fftw lua regex sdl2 zlib curl

sudo ./cross-libs.sh install bzip2 fftw lua regex sdl2 zlib curl

If the script doesn't run, you need to allow the file to be run as an executable. To do this, use chmod +x cross-libs.sh

Compile

It should be as simple as scons --win

Some SConscript changes may be needed if the name of your cross compiler isn't standard (or just not listed in the SConscript). If it does not detect your cross compiler, try using: scons --win --tool=$MINGW-
Notice the dash, if for you $MINGW is i586-mingw32msvc you should pass --tool=i586-mingw32msvc-.

If you have problems with initial libraries lookup, it is useful to check config.log for obvious failures.

If when linking it gives you an error like

/usr/lib/gcc/i586-mingw32msvc/4.2.1-sjlj/libstdc++.a(stubs.o):(.text+0x540): multiple definition of `_coshf'

build/src/Misc.o:Misc.cpp:(.text$coshf[_coshf]+0x0): first defined here

do this (under root):

cd /usr/lib/gcc/$MINGW/4.2.1-sjlj/

$MINGW-ar -d libstdc++.a stubs.o
