This document contains instructions to build Wireshark natively on Windows
using GCC and MinGW-w64 with the MSYS2 distribution.
Steps to setup the build environment:
1. Download and install MSYS2 from
2. Open the MSYS2 MSYS shell.
3. Update with "pacman -Syu" as many times as necessary. You may also wish
to install base-devel at this point: pacman -S base-devel. Anytime you
want to run pacman it's recommended to do so from the MSYS shell.
4. Install pactoys for convenience:
$ pacman -S pactoys-git
5. Install the toolchain:
$ pacboy -S toolchain:x cmake:x ninja:x ccache:x
From this point on it's a typical ninja build:
1. Open the MSYS2 MINGW64 shell.
2. Create the build directory. This example will assume the build directory
is under the source directory:
$ cd $srcdir && mkdir build && cd build
3. Run cmake:
4. Instal missing dependencies using pacman (there are a few minor gaps) and
re-run cmake, e.g.:
$ pacboy -S glib2:x libpcap:x libgcrypt:x gnutls:x qt5:x
5. Build by running "ninja" in the build directory:
$ ninja
There isn't a native git package provided with MSYS2 so it's recommended that
you continue using the Git-For-Windows installer (or see [1]).
Currently the Wireshark MinGW-w64 build using MSYS2 has the following
* The ETW extcap (etwdump) does not build.
* Some optional dependencies are not available in the official MSYS2
repositories. These will be provided at a later date.
* Currently there is no Wireshark binary package available. More work is
needed to implement this. To be decided if it will use NSIS or something
* Many compiler warnings to be fixed.
