Get it Running

Gentoo

Installing the Libraries

Install the following libraries:

• SDL main, media-libs/libsdl, web: ​link
• SDL image, media-libs/sdl-image, web: ​link
• SDL true type fonts, media-libs/sdl-ttf, web: ​link
• SDL mixer, media-libs/sdl-mixer, web: ​link

Here are the explicit 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-mixer
...

Gentoo is now ready to compile and run orxonox

Getting the Source

First of all you will 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 the subversion program

wraith user # emerge subversion

Check out the source via svn anonymous, this will download the hole project to the directory orxonox-dir

wraith user # svn co http://svn.orxonox.ethz.ch/reporx/orxonox orxonox-dir

You won't be able to commit (check in) anything with the anonymous repository. You have to ask us for user/pass combination. If you have already an account check it out like this:

wraith user # svn co https://svn.orxonox.ethz.ch/reporx/orxonox orxonox-dir

You will be asked for user name and password, that you have from us.

Compiling

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

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

Profiling

If you want to profile (performance measuring) Orxonox 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, so don't be embarassed!

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

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

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