This howto explains how to build the MS Windows version of X2Go Client. This howto explains how to build the 32-bit version of X2Go Client on MS Windows. If someone successfully attempts a 64-bit (which should work, but needs to be tested), please contribute to this wiki page.
X2Go Cltient for Windows needs several 3rd-party programmes for being able to run on MS Windows:
All these programmes can be built from source, downloaded from our server or from their project sites. You can also copy the 3rd-party components from X2Go Client installation (on MS Windows) directory.
MSysGit provides a Unix-like shell (bash) environment, so that you can use Git easily from the command line.
Notepad2 is a freeware alternative to Notepad shipped with Microsoft Windows. Notepad2 understands UTF-8 text formats (and others) and can handle Unix-style line endings. In case you want to introspect a code file, this tool is very handy.
MinGW is a gcc compiler for Windows. You need it to build X2Go Client. For the time being, X2Go Client uses Qt 4.8.5 specifically. Qt-4.8.5 for Windows should be used with MinGw-4.4. Unfortunately, you can not download binaries for this version from MinGW project site any more. You can build it from source or download it from X2Go Site
Extract it to your disk (
D:\mingw in this example).
Finally, you have to add these MinGW executable directories to your PATH environment variable:
You need Qt to build X2Go Client from source. Qt-4.8.5 is tested and recommended for current version of X2Go Client.
Download and install the MinGW version of Qt-4.8.5 for Windows from here
In this example D:\Qt will be chosen as installation directory
As X2Go Client needs a Qt with SSL support you must install OpenSSL for MS Windows. OpenSSL depends on the Microsoft Visual C++ 2008 Redistributables. Get that (32-bit version, x86) from the Microsoft site and install it prior to installing OpenSSL.
Download the OpenSSL installer for Windows by browsing here and selecting “Win32 OpenSSL v1.0.1*” where “1.0.1*” s the current version. You can also download it from our site, but only do so if we have the current version. Install it on your build system (for example to directory
After installation, copy OpenSSL header files into MinGW's include directory:
d:\OpenSSL-Win32\include\openssl -> d:\mingw\include\openssl
It is recommended to configure Qt to build statically linked applications. It will take some time to reconfigure Qt for static builds. You surely can skip this step, but in this case you must provide Qt libraries with your X2Go Client binary.
Open Qt Command Prompt and start configuration script
$ configure -release -static -openssl
$ make sub-src
If you choose to build dynamically linked applications with Qt, you still have to rebuild Qt in order to get OpenSSL support into Qt.
Open Qt Command Prompt and start configuration script
$ configure -release -openssl
$ make sub-src
You need libssh to build X2Go Client.
Get libssh library package built with MinGW from here on our site.
Extract files from archive.
Copy headers files in “include” directory of MinGW
libssh\include\libssh → d:\mingw\include\libssh
Copy library files in “lib” directory of MinGW
libssh\lib\*.* → d:\mingw\lib\
Open Qt Command Prompt, change to your build directory and get X2Go Client sources from git
$ git clone git://code.x2go.org/x2goclient.git
Build X2Go Client
$ cd x2goclient $ PATH=%PATH%;D:\MinGW\libexec\gcc\mingw32\4.4.0\ $ config_win.bat $ mingw32-make
X2Go Client (x2goclient.exe) binary is in d:\build\x2goclient\release directory
You may want to pack X2Go Client to reduce it size. You can do it with upx, which is available for Windows, Linux and Cygwin.
To make X2Go Client usable on Windows, you must put X2Go Client binary and all libraries and components in one directory.
In the base directory of your X2Go Client source tree create a folder named
dist/. To this folder you have to add the following components:
release/folder) to the
dist/folder (built from nx-libs.git on http://git.x2go.org):
If you want to build nxproxy from source, you need install and configure Cygwin first.
Download and start the Cygwin installer
Choose your cygwin directory. For example c:\cygwin. Follow installer instructions.
on installer page “Select Packages” you can select programs and libraries that should be installed in your cygwin environment. For building of nxproxy you will need:
libjpeg-develpackage, you are now installing libjpeg-turbo instead of the legacy libjpeg . The same applies for the dependency
libjpeg8package, which provides the cygjpeg-8.dll file that you will copy later.
If you are updating the X2Go Windows build VM, X2Go-WinBuilder, install these packages too:
You will need a libpng12 to build nxproxy. This version of libpng is not available on current version of cygwin. You should install it manually.
$ cd /usr/src
$ wget http://downloads.sourceforge.net/project/libpng/libpng12/1.2.51/libpng-1.2.51.tar.gz $ tar -xzvf libpng-1.2.51.tar.gz $ cd libpng-1.2.51
$ ./configure --prefix=/usr/ $ make && make install
$ cd /cygdrive/d/Build
$ wget http://code.x2go.org/releases/source/nx-libs/nx-libs-184.108.40.206-lite.tar.gz $ tar -xvzf nx-libs-220.127.116.11-lite.tar.gz $ cd nx-libs-18.104.22.168
$ cd nxcomp $ autoconf $ ./configure $ make $ cd ..
$ cd nxproxy $ autoconf $ ./configure $ make $ strip nxproxy.exe $ cd ..
Now the nxproxy binary (nxproxy.exe) is ready. You can copy it into the programme packaging folder (
dist/) of X2Go Client. To be able to run nxproxy you must also copy required libraries into the
X2Go Client for Windows using modified Cygwin Open SSH Server for file sharing. You can download it here
If you want to build it from source, you should install Cygwin first.
After that run Cygwin installer (setup.exe), navigate to “Select Packages” page and install additional packages, you need to build Open SSH Server:
For openssh you should install both, binary and source packages (toggle “Src” checkbox beside of package name). Source package will be installed in /usr/src directory in your Cygwin installation.
Copy the source folder (downloaded and extracted from a tarball by cygwin) to your build directory. In this example d:\Build will be used
$cp -pr /usr/src/openssh-6.1.1p1-3-src /cygdrive/d/Build/
cd to the openssh source directory, extract the upstream (openssh.com) tarball within, and cd to the lower-level source directory
$cd /cygdrive/d/Build/openssh-6.6.1p1-3 $tar -xzvf openssh-6.6p1.tar.gz $cd openssh-6.6p1
Apply any patches that cygwin provides. For example, with 6.6p1-3:
$patch < ../curve25519-sha256.patch
Get and apply the X2Go patch, which enables use of the Open SSH Server with X2Go Client
$cd .. $wget http://code.x2go.org/releases/source/openssh-cygwin/openssh-6.0p1-2.x2go.patch ../ $cd openssh-6.6p1 $patch.exe < ../openssh-6.6p1-1.x2go.patch
Build Open SSH Server
$./configure --libexecdir=/usr/sbin --with-kerberos5=/usr --with-tcp-wrappers --with-libedit --with-xauth=/usr/bin/xauth --build=mingw32 $make $strip *.exe
Open SSH Server binaries are ready. Now you can copy them in to the installation directory of x2goclient:
To be able to run Open SSH Server you should also copy needed programs and libraries from cygwin directory (c:\cygwin\bin):
Some of this libraries are also used by nxproxy. Open SSH Server and nxproxy should be built using same version of Cygwin.
You can download PulseAudio 5.0 for Windows here.
Prior versions of PulseAudio are available from project site and the above link.
All official X2Go Project builds use the 32-bit builds of VcXsrv. 64-bit builds are probably compatible with the 32-bit X2Go Client, but have not been tested.
Also, you are doing an official X2Go Project build, use the latest version that is still compatible with Windows XP: 22.214.171.124
If you do download VcXsrv from the project site, deselect to install the fonts. They would more than double the size of the X2Go NSIS installer. Some legacy apps do need them, and users can install them if they'd like
Also, if you are doing an official X2Go Project build, remove these files that X2Go Client does not need and would take up extra space:
Also, if you are doing an official X2Go Project build, create this file in the VcXsrv folder:
And specify the version string of VcXsrv in it. The version string should be the only contents of the file. For example:
you can download PuTTY for Windows from project site. Building PuTTY from source is not the part of this Howto
These are the only binaries you need from PuTTY. Copy them directly into the
