This guide is to help developers setup development environment quickly.

Warning! the compilation will require ~10 GB of free space to compile & run qBittorrent (dynamically linked).

Refer to https://www.msys2.org/

Depending on your intention, download one PKGBUILD from the links below and put it into a clean folder.

• Build development source
  https://raw.githubusercontent.com/Chocobo1/qbittorrent_msys2/master/PKGBUILD

• Build stable release
  Download every file in this folder: https://github.com/msys2/MINGW-packages/tree/master/mingw-w64-qbittorrent
  To download each file, click the filename then on the right side click Raw button and Ctrl + s to save the file.

If you want to build a x64 application then open MSYS2 MinGW 64-bit in Windows start menu. Otherwise open MSYS2 MinGW 32-bit.

First make sure msys2 is up-to-date by running the following command a few times, until it tells you all packages are latest:

pacman --sync --refresh --sysupgrade

Install development tools:

pacman --sync --noconfirm mingw-w64-x86_64-toolchain
# run the below command if you need to build 32-bit
pacman --sync --noconfirm mingw-w64-i686-toolchain

Start building qBittorrent:

cd <PKGBUILD_directory>
# build 64-bit qBittorrent
MINGW_ARCH=mingw64 makepkg-mingw --skippgpcheck --syncdeps --noconfirm
# build 32-bit qBittorrent
MINGW_ARCH=mingw32 makepkg-mingw --skippgpcheck --syncdeps --noconfirm

After the command complete, you should see it created package: mingw-w64-x86_64-qbittorrent-4.0.1-1-any.pkg.tar.xz. The architecture & version number may be different.

Install:

pacman -U mingw-w64-x86_64-qbittorrent-4.0.1-1-any.pkg.tar.xz

Run (in the same console):

qbittorrent

You can find the downloaded qBittorrent source code in <PKGBUILD_directory>/src/qbittorrent.
