mini howto: Compiling under Ubuntu Gutsy

[Tuxer]

First: This is just really, really great news!!!

I just compiled Lux and here is what I had to do:

UPDATE4: Added libwxgtk2.8-dev (19.6.2008).
UPDATE3: Tested on clean install and added some missing deps (31.12.2007).
UPDATE2: I've added new dependencies to the list, thanks HyperCity.
UPDATE: I've added new dependencies to the list (This should work, let me know if there are problems)

Compiling Lux in Ubuntu Gutsy/Hardy:

developing tools:

Code: Select all

sudo apt-get install cvs
sudo apt-get install build-essential
sudo apt-get install cmake


Depencies as a one command:

Code: Select all

sudo apt-get install bison flex libboost-dev libfltk1.1-dev libboost-thread-dev libboost-date-time-dev libboost-program-options-dev libboost-filesystem-dev libopenexr-dev libboost-iostreams-dev libboost-regex-dev libboost-serialization-dev libboost-wave-dev libtiff4-dev libpng12-dev libwxgtk2.8-dev

And then just follow this:

EDIT: Here you can find more official version by Radiance: http://www.luxrender.net/wiki/index.php ... g_on_Linux

Hope this is useful for others.

Hi Tuxer,
Glad to see building scripts are working on Ubuntu ! But again, beware....you'll get a slow unstable version with all debugging features on

I don't mind

Ok, compiles fine but rendering won't work. This maybe not a right place for this but here is a backtrace of it:

Mhh...did you load a scene ? If you just clicked on the 'play' button...that's the normal behavior

[Tuxer]

Yes, I loaded the example scene from examplescenes directory. Are those valid files? I now noticed that loading them results errors:
Error: Scene description must be inside world block; "ObjectEnd" not allowed. Ignoring.
Line 126924, file /home/ari/Programs/Lux/lux/testscenes/sunsky_test/geom-sunsky_test.lux

[jromang]

Those are the test scenes Radiance used for the sunsky light implementation...don't know if they are still valid
Maybe you could try this one ?

[Tuxer]

Maybe you could try this one ?

Thank you! That worked fine, so I guess those .lux files are not valid any more.

On a similar note - the present cvs tree keeps crashing on me whatever file(s) I give it as input. I'm using kubuntu 7.04
which comes with the ubuntu 1_33 BOOST libraries - the BOOST headers in cvs seems to indicate 1_34_1 so perhaps the problem is there. I'm having serious problems following the boost-code in gdb (the segfault is in there somewhere) - it's a bloody mess of vtables, STL and whatnot. I'm basically getting nowhere atm. I'll try uninstalling the 1.33 libraries and compiling the 1.34 ones by hand. Hopefully that'll sort it out.

[tomb]

To follow-up on myself - the segfaults in boost was indeed the result of a mismatch of lux headerfiles (1.34) and kubuntu's installed boost environment (1.33.1). Removing kubuntu's version and compiling the 1.34 release by hand resolved the problem.

libboost-iostreams-dev libboost-regex-dev libboost-serialization-dev libboost-wave-dev extra boost libs on my sistem for succesfull building the regular libs should install as dependencees, thx for the tut and sory for my english
