How did we build windows version

Mon, 07 Mar 2016 13:46:17 +0100

TL;DR

Thanks to Appveyor

CoyIM is currently built using Appveyor ci, it’s a similar tool like Travis for Windows platform, if you’d like to know how we use appveryor, please refer to our .appveyor file in repo.

GTK dependencies

CoyIM is a GUI application with GTK support(using GoTK, a wrapper in golang), so it requires a build environment like other GTK applications.

MSYS2 and MinGW

Right now MSYS2 and MinGW are the most common way to setup GTK env on windows. It’s by default with the features provided by Pacman, a package tool on Arch Linux, You can imagine a small linux virtual environment in windows, that’s MSYS2, although all the dependencies are actually natively built from source on windows.

The file ci/install-deps-windows.bat in repo describe the way to install MSYS2 and MinGW and also using pacman to resolve all the dependencies we need.

MSYS2 & MinGW:

download from https://sourceforge.net/projects/msys2/
unzip it into any place you want, u will see a cute bash in \usr\bin\

Pacman:

pacman --noconfirm --needed -Sy make gcc
pacman --noconfirm --needed -Sy mingw-w64-x86_64-gtk3

These packages are actually compiled on windows, and you can directly use it as DLL for any applications. Check them in /mingw64/**/*.dll.

Golang

Golang has a nice compiler on windows, and we actually did nothing special to make it work for CoyIM.

CLI version (xmpp-client)

Now we don’t have client version on windows, because it uses a system call which doesn’t exist on Windows OS. And it won’t have good experience when you use it on CMD.exe or PowerShell, because of the UNIX prompt color.

If any idea/doubt about this, feel free to contact with us on Github or Twitter.

Welcome to CoyIM!

coyim - a safe and secure chat client

CoyIM is a new client for the XMPP protocol. It is built upon https://github.com/agl/xmpp-client. It adds a graphical user interface and tries to be safe and secure by default. Our ambition is that it should be possible for even the most high-risk people on the planet to safely use CoyIM, without having to make any configuration changes.

To do this, we enable OTR by default, we try hard to use Tor and Tor hidden services, and also to use TLS and TLS certificates to verify the connection. The implementation is written in the Go language, to avoid many common types of vulnerabilities that come from using unsafe languages.

Security warning

CoyIM is currently under active development. There have been no security audits of the code, and you should currently not use this for anything sensitive.

Installation instructions

GUI version

The GUI version requires GTK+ >= 3.6.16, which installation depends on your OS:

Ubuntu:

sudo apt-get install -qq -y gtk+3.0 libgtk-3-dev

Mac:

brew install gtk+3

Then install coyim:

GTK_VERSION=$(pkg-config --modversion gtk+-3.0 | tr . _ | cut -d '_' -f 1-2)
go get -u -tags "nocli gtk_${GTK_VERSION}" github.com/twstrike/coyim

CLI version (xmpp-client)

go get -u github.com/twstrike/coyim
