Gentoo

TracNav(TracNav/TOC)?

1. Get the ebuild: source:/trunk/scripts/gentoo#HEAD (download newest ebuild)
2. Change to root user

   wraith root # su -
   

3. Copy the ebuild to /usr/portage/games-action/orxonox (and create new directory)

4. wraith root # cd /usr/portage/games/action/orxonox
   wraith root # ebuild orxonox-*.ebuild digest
   wraith root # emerge orxonox
   

From now on you should be able to play Orxonox, and if you have subversion installed and a login, you will also be able to develop.

Installing the Libraries

Install the following libraries:

• SDL main, media-libs/libsdl, web: ​http://www.libsdl.org/
• SDL_image, media-libs/sdl-image, web: ​http://www.libsdl.org/SDL_image
• SDL_(true type fonts), media-libs/sdl-ttf, web: ​http://www.libsdl.org/SDL_ttf
• SDL_net, media-libs/sdl-net, web ​http://www.libsdl.org/SDL_net

Here are the commands to enter:

wraith root # emerge media-libs/libsdl
...
wraith root # emerge media-libs/sdl-image
...
wraith root # emerge media-libs/sdl-ttf
...
wraith root # emerge media-libs/sdl-net
...

Gentoo is now ready to compile and then run Orxonox.

Getting the Source Code

First of all you have to install subversion on your system: Make sure, that you have ssl included in your make.conf file:
/etc/make.conf

 ...
 USE="..., ssl, ..."
 ...

now emerge subversion

wraith user # emerge subversion

Check out the source via anonymous subversion login. This will download the whole project to the directory orxonox-dir.

wraith user # svn co http://svn.orxonox.net/orxonox orxonox-dir

You won't be able to commit your own code (check in) with the anonymous subversion repository. You have to ask us for a username/password combination. If you already have an account, check it out like this:

wraith user # svn co https://svn.orxonox.net/orxonox orxonox-dir

You will be asked for your username and password, that you got from us.

Compiling

Just change into the trunk directory, then execute configure and make….

wraith user # cd ./orxonox/trunk/
wraith user # ./autogen.sh
wraith user # ./configure
...
wraith user # make
...
wraith user # cd src
wraith user # ./orxonox

Profiling

If you want to profile Orxonox (measure its performance) you will probably want to view the statistics in a special program like kprof. On Gentoo systems you can just emerge it:

wraith root # emerge kprof

Orxonox runs much much slower with profiling enabled.

wraith user # cd ./orxonox/trunk/
wraith user # ./configure --enable-profile
...
wraith user # make
...
wraith user # cd src
wraith user # ./orxonox

Orxonox now runs very slow and writes its profiling stats to a file called gmon.out. Remember that _only_ the functionalities you use while profiling will be profiled (since the profile log is written while the program is been executed).
After you exit the Orxonox, you can parse the output file and then be able to open it in kprof:

wraith user # gprof -b ./orxonox > text.out
wraith user # kprof -f text.out
