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 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 dependencies 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
