| − | This guide covers the installation of freeNX and the supporting NX environment from the source code. NX is a remote desktop application for linux machines. It is extremely bandwidth optimized and has clients for every platform.Look [http://en.wikipedia.org/wiki/NX_technology here ]for details.<br>

| − | | |
| − | Originally created by [http://www.nomachine.com Nomachine], it has an open source clone called [http://freenx.berlios.de/ FreeNX].<br>
| |
| − | | |
| − | This app is very useful if you plan to access your IGEP board from remote and don't want to get only a simple shell prompt.These instructions have been proven to work on a standard Ubuntu 10.10 system. Instructions MAY work in other Ubuntu versions or Debian. They will probably not work for other non-Debian distros. If you use Gentoo, the whole NX system is available as a package in emerge.<br>
| |
| − | | |
| − | <br>
| |
| − | | |
| − | '''First thing''': NX works at its best with gnome installed at server side. <u>Don’t use XFCE, it won’t work with this guide</u>. <br>
| |
| − | | |
| − | Prerequisites:<br>
| |
| − | | |
| − | #A working IGEPv2 board with Ubuntu maverick or lucid installed. Everything will be done from the IGEP board itself, not on a supporting computer.
| |
| − | #Network connection
| |
| − | #A working SSH server (I assume you are trying to build a headless computer, buti f you got mouse/keyboard/monitor and work locally, these instructions are still valid)
| |
| − | #A basic knowledge of the linux shell
| |
| − | #Good will, coffee, patience, and all the other stuff normally needed when you go for source code compiling.
| |
| − | | |
| − | <br>
| |
| − | | |
| − | '''IMPORTANT''': if you find errors and the software does not compile, don't start immediately to ask for help, every system installation is different. There is surely a library header, a development utility or something else you did not install or that was not present on your system: read carefully the last lines of the error log, figure out, google a bit and don't worry, it’s not at all difficult.

| |
| − | | |
| − | Let's start:
| |
| − | | |
| − | 1. If you don’t have a desktop manager installed, install gnome-desktop (don’t install the full ubuntu-desktop unless you really need it, it will install production packages like OpenOffice.org and Gimp)<br>
| |
| − | <pre>sudo apt-get install gnome-desktop</pre>
| |
| − | <br>2. Install the build environment and some supporting libraries and tools (NOTE: if you need a complete build environment, look at other infos [http://labs.igep.es/index.php/How_to_setup_a_development_environment here]) | |
| − | <pre>sudo apt-get install build-essential libjpeg62-dev libpng12-dev xutils-dev cups expect netcat
| |
| − | </pre>
| |
| − | Before you start asking: Yes, you need cups even if you’ll never use a printer. NX won’t build without it installed<br>
| |
| − | | |
| − | <br>
| |
| − | | |
| − | 3. Create a work directory in your home and enter it<br>
| |
| − | <pre>mkdir freenx
| |
| − | cd freenx
| |
| − | </pre>
| |
| − | <br>
| |
| − | | |
| − | 4. Download all the source packages (packages are taken [http://prdownload.berlios.de/freenx/freenx-server-0.7.3.tar.gz here ]and [http://www.nomachine.com/sources.php here ])<br>
| |
| − | <pre>wget http://download.berlios.de/freenx/freenx-server-0.7.3.tar.gz
| |
| − | wget http://64.34.161.181/download/3.4.0/sources/nxproxy-3.4.0-2.tar.gz
| |
| − | wget http://64.34.161.181/download/3.4.0/sources/nxcomp-3.4.0-7.tar.gz
| |
| − | wget http://64.34.161.181/download/3.4.0/sources/nxcompext-3.4.0-1.tar.gz
| |
| − | wget http://64.34.161.181/download/3.4.0/sources/nxssh-3.4.0-2.tar.gz
| |
| − | wget http://64.34.161.181/download/3.4.0/sources/nxcompsh-3.4.0-2.tar.gz
| |
| − | wget http://64.34.161.181/download/3.4.0/sources/nxcompshad-3.4.0-3.tar.gz
| |
| − | wget http://64.34.161.181/download/3.4.0/sources/nx-X11-3.4.0-4.tar.gz
| |
| − | wget http://64.34.161.181/download/3.4.0/sources/nxauth-3.4.0-3.tar.gz
| |
| − | wget http://64.34.161.181/download/3.4.0/sources/nxagent-3.4.0-11.tar.gz
| |
| − | </pre>
| |
| − | <br>
| |
| − | | |
| − | 5. Unpack everything<br>
| |
| − | <pre>tar zxvf *.tar.gz
| |
| − | | |
| − | </pre>
| |
| − | There will not be a single directory for each one of the unpacked archives as some of these will unpack under the nx-X11 folder. If you have trouble unpacking everything at once, do it file by file.<br>
| |
| − | | |
| − | <br>
| |
| − | | |
| − | 6. Now enter the nx folders and build everything (leave only the nx-X11 apart)<br>
| |
| − | <pre>cd <every single folder>
| |
| − | ./configure
| |
| − | make
| |
| − | </pre>
| |
| − | <br>
| |
| − | | |
| − | 7. Then enter the X folder and make the whole server<br>
| |
| − | <pre>cd nx-X11
| |
| − | make World
| |
| − | | |
| − | </pre>
| |
| − | '''NOTE''': This operation will take a LONG time. Explanation: this step actually builds the complete Xfree86 with custom modifications from NX. <br>
| |
| − | | |
| − | <br>
| |
| − | | |
| − | 8. Copy some the compiled libraries in the NX folder (all the following commands have to be done as superuser with sudo)<br>mkdir /usr/NX<br>
| |
| − | <pre>cp -a nx-X11/lib/X11/libX11.so* ${NXPREFIX}/lib
| |
| − | cp -a nx-X11/lib/X11/libX11.so* ${NXPREFIX}/lib
| |
| − | cp -a nx-X11/lib/Xext/libXext.so* ${NXPREFIX}/lib
| |
| − | cp -a nx-X11/lib/Xrender/libXrender.so* ${NXPREFIX}/lib
| |
| − | cp -a nxcomp/libXcomp.so* ${NXPREFIX}/lib
| |
| − | cp -a nxcompext/libXcompext.so* ${NXPREFIX}/lib
| |
| − | cp -a nx-X11/programs/Xserver/nxagent ${NXPREFIX}/bin
| |
| − | cp -a nxproxy/nxproxy ${NXPREFIX}/bin
| |
| − | cp /usr/NX/lib/libXcomp* /usr/lib
| |
| − | cp /usr/NX/bin/nxagent /usr/bin/
| |
| − | </pre>
| |
| − | <br>
| |
| − | | |
| − | 9. There is an error in the freenx installer, you need to manually create a link to a library<br>
| |
| − | <pre>sudo ln -s /usr/NX/lib/libXrender.so.1.2.2 /usr/NX/lib/libXrender.so.1.2
| |
| − | </pre>
| |
| − | <br>
| |
| − | | |
| − | 10. Now enter the freenx folder and build the server<br>
| |
| − | <pre>cd freenx-server-0.7.3
| |
| − | NXPREFIX=/usr/NX
| |
| − | patch -p0 < gentoo-nomachine.diff
| |
| − | make
| |
| − | sudo make install
| |
| − | </pre>
| |
| − | <br>
| |
| − | | |
| − | 11. Now configure your NX server (follow the insttructions and ignore warnings about the nxagent without version string, it is a known and uncorrected bug) <br>
| |
| − | <pre>and you are done
| |
| − | export PATH=$PATH:/usr/NX/bin
| |
| − | sudo nxsetup --install
| |
| − | </pre>
| |
| − | <br>
| |
| − | | |
| − | Now you '''should '''have a working NX server. If not, check the error logs in the NX client and ad try to get a clue. The installation has been tried with XFCE and it did NOT work at all, so don't even try to understand why (unless you have a lot of spare time to do it): use Gnome.<br>
| |
| − | | |
| − | <br>
| |
| − | | |
| − | Just connect to your IGEPv2 box using one of the the NX clients found on www.nomachine.com.<br><br>
