Editing Compiling FileZilla 3 under Windows

This documentation explains how to setup a build environment for [[FileZilla 3]] and how to compile it under Windows using [http://msys2.github.io/ msys2]. Msys2 is a cygwin environment. These instructions require you to run a 64bit Windows.

It will take some time to get everything working, but you will be able to use the build environment for other programs too.

For complete MSYS2 system and all needed decencies installed, you will need 7GiB free space on your disk.

'''Note to wiki contributors: Do not change version numbers on your own. The build process is somewhat fragile and does break if you change things'''

__TOC__

=Installing the MSYS2 environment=

Download the 64bit MSYS2 installer and install it in a convenient location: [https://repo.msys2.org/distrib/x86_64/msys2-x86_64-20220118.exe msys2-x86_64-20220118.exe]

=Installing the compiler toolchain=

FileZilla's shell extension needs to be build both for 32bit as well as 64bit, hence we're going to need compilers for both 32bit and 64bit.

==  Tools and compiler ==

===First update===
Start the MSYS2 MinGW 64-bit shell
 pacman -Syu
close MSYS2 shell. Repeat until there are no more updates.

===Install tools and compiler toolchain===

Start MSYS2 MinGW 64-bit shell, execute the following command to install the necessary packages:

 pacman -S autoconf automake libtool make mingw-w64-i686-toolchain mingw-w64-x86_64-toolchain git svn

Execute the following to work around some most-annoying bugs in the toolchain

 # Fix missing platform prefix for windres
 [ -f /mingw64/bin/x86_64-w64-mingw32-windres.exe ] || ln -s /mingw64/bin/windres.exe /mingw64/bin/x86_64-w64-mingw32-windres.exe
 [ -f /mingw32/bin/i686-w64-mingw32-windres.exe  ] || ln -s /mingw32/bin/windres.exe /mingw32/bin/i686-w64-mingw32-windres.exe

== Setting up the environment==

Execute the following commands:
 mkdir ~/prefix
 echo 'export PATH="$HOME/prefix/bin:$HOME/prefix/lib:/mingw64/bin:/mingw32/bin:$PATH"' >> ~/.profile
 echo 'export PKG_CONFIG_PATH="$HOME/prefix/lib/pkgconfig"' >> ~/.profile
 echo 'export PATH="$HOME/prefix/bin:$HOME/prefix/lib:/mingw64/bin:/mingw32/bin:$PATH"' >> ~/.bash_profile
 echo 'export PKG_CONFIG_PATH="$HOME/prefix/lib/pkgconfig"' >> ~/.bash_profile
 echo 'export LC_ALL=C' >> ~/.bash_profile

Restart the MSYS2 MINGW64 shell.
