Compiling FileZilla 3 under Windows

From FileZilla Wiki
Jump to navigationJump to search

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

Installing the MSYS2 environment

Download the 64bit MSYS2 installer and install it in a convenient location: msys2-x86_64-20180531.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="$HOME/prefix/bin:/mingw64/bin:/mingw32/bin:$PATH"' >> ~/.profile
echo 'export PKG_CONFIG_PATH="$HOME/prefix/lib/pkgconfig"' >> ~/.profile
echo 'export PATH="$HOME/prefix/bin:/mingw64/bin:/mingw32/bin:$PATH"' >> ~/.bash_profile
echo 'export PKG_CONFIG_PATH="$HOME/prefix/lib/pkgconfig"' >> ~/.bash_profile

Restart the MSYS2 MINGW64 shell.
