Hi all,

Again I seem to have made some wrong assumptions. After closer 
inspection, it seems that the windows x2goclient isn't fully statically 
linked. It seems that only the Qt libraries have been linked against 
statically. I believe that was probably done by doing a manual build of 
Qt using "configure -static" (note that I've never compiled Qt myself 
from source, so I'm just copying this blindly from the "Deploying an 
Application on Windows" page in the Qt 4.8 documentation on the 
qt-project.org web site). Since I just use the downloaded Qt 
distribution for MinGW, I probably can't reproduce this without 
compiling a static version of Qt myself.

Apart from the static linking of Qt libraries, I think I have now more 
or less created a usable build of the x2goclient, using the instructions 
below (enhanced from what I posted before).

I'll now try to add HTTP proxy support (using corkscrew) into this.

Download MingW installer from:
https://sourceforge.net/projects/mingw/files/Installer/mingw-get-inst/

get the latest mingw-get-inst-*.exe file

Run the installer, install in C:\sw\MinGW after installation, run 
C:\sw\MinGW\msys\1.0\msys.bat (or open the shortcuts in your start 
menu/desktop if you installed any)

     cd /c/sw/MinGW/msys/1.0/postinstall
     sh ./pi.sh

Create c:\home
On My Computer->Properties->Advanced->Environment Variables, set
     HOME=c:\home

Create C:\home\.profile

     PATH=$PATH:/c/sw/Qt/4.8.1/bin
     export PATH

Download QT from:
http://releases.qt-project.org/qt4/source/qt-win-opensource-4.8.1-mingw.exe
install in c:\sw\Qt
Make sure to point to the MinGW installation used above.

Download libssh and libz from:
http://winkde.org/pub/kde/ports/win32/repository-4.8/win32libs/libssh-x86-mingw4-0.5.2-1-bin.tar.bz2
http://winkde.org/pub/kde/ports/win32/repository-4.8/win32libs/libssh-x86-mingw4-0.5.2-1-lib.tar.bz2
http://winkde.org/pub/kde/ports/win32/repository-4.8/win32libs/zlib-x86-mingw4-1.2.5-1-bin.tar.bz2
http://winkde.org/pub/kde/ports/win32/repository-4.8/win32libs/zlib-x86-mingw4-1.2.5-1-lib.tar.bz2

(libssh seems to be very hard to compile on mingw. Its build-system is 
based on CMake, which I don't think is available on mingw. The KDE 
people have done the hard work however, so we use their results)

cd /usr/local
tar zxf .../path/to/libssh-x86-mingw4-0.5.2-1-bin.tar.bz2
tar zxf .../path/to/libssh-x86-mingw4-0.5.2-1-lib.tar.bz2
tar zxf .../path/to/zlib-x86-mingw4-1.2.5-1-bin.tar.bz2
tar zxf .../path/to/zlib-x86-mingw4-1.2.5-1-lib.tar.bz2

Build a custom version of openssl ("mingw-get install msys-openssl" 
doesn't seem to install a compatible version, as static linking doesn't 
work with that one).

Download OpenSSL from:
http://www.openssl.org/source/openssl-1.0.1c.tar.gz

cd ~
tar zxf /path/to/openssl-1.0.1c.tar.gz
cd openssl-1.0.1c
./configure mingw --prefix=/usr/local
make
make install
(make install takes a long time, it installs like 10K man pages, 
somebody could probably find out how to install this without man pages 
in order to speed this up)

Download x2goclient source code from:
http://code.x2go.org/releases/source/x2goclient/x2goclient_3.99.2.0.tar.gz

cd ~
tar zxf /path/to/x2goclient_3.99.2.0.tar.gz
cd x2goclient_3.99.2.0
Edit x2goclient.pro file
Replace the part that says:

     win32-* {
        message(building $$TARGET for windows without ldap and cups)
        LIBS += -lwinspool -lws2_32
        CONFIG += static release
     }

with:

     win32-* {
         message(building $$TARGET for windows without ldap and cups)
         INCLUDEPATH += /usr/local/include
         LIBPATH += /usr/local/lib
         LIBS += -lssl -lcrypto -lwinspool -lws2_32
         CONFIG += static release
         QMAKE_LFLAGS += -static-libstdc++
     }

make build_client
