libopenvrml5-dev & libxul-dev request removal of packages

[HugoRune]

(System: Ubuntu edgy 64bit with kubuntu-desktop installed)

I want to use the openvrml library in a project

So I tried to install libopenvrml5-dev

This is dependant on libxul-dev, which in turn is dependant on
libnss3-dev
libnspr4-dev
libmozjs-dev

When I install either libopenvrml5-dev or libxul-dev, synaptic just displays a message that it depends on that "but it is not going to be installed" and stops. Adept fails in a similar way.

If I try to install libnss3-dev, libnspr4-dev or libmozjs-dev manually the package manager wants to remove a lot of packages, among them:

Anjuta
Evolution
Firefox
nautilus
ubuntu-desktop
gnome-session
gnome-terminal
gnome-app-install

I definitely need some of these, especially firefox, and I am afraid to remove the rest either, so is there a way to install the openvrml libraries for me?


UPDATE:
I am currently trying to build openvrml from source. If that works I probably will not need that package after all. Still, I am curious how to solve this sort of problem.

Alright Hugo, how's the building openvrml going? I'm trying to get it on my 6.06 to use it with GEANT4. Fucken nightmare.

I managed to compile it a while ago, i made the following notes about the process

requires boost
configure does not notice missing boost
--> installed libboost-dev 1.33.1 7ubuntu1
requires boost-thread
configure does not notice missing boost-thread, no mention in manual
quite confusing error-message
--> installed libboost-thread 1.33.1 7ubuntu1 and libboost-thread-dev

I may have had to install a couple of other libraries before that.
Afterwards, compiling took almost 30 hours

But the whole thing seemed quite useless, choking on simple vrml files and making mistakes while parsing.

Currently I am using openSG 1.8 (newest version) to parse vrml, which works quite nice.

Jalirious;

I know that people use the VRML2 output format with FreeWRL; seems to work.

notes from the FreeWRL maintainer (me)

1) the latest parser crashes if you specify vrml1 as an output. I'll put a check into the code before the next release;

2) next release; I've currently got a colleague creating and testing rpms for Fedora Core 6 of the latest and greatest code; final touches going in shortly; after that comes the latest Ubuntu for i386 and amd-64.

3) OpenVRML is a *good* piece of software - Braden, the creator, is a very bright person; if you want to keep on with the OpenVRML build - no problem.

If you decide to use FreeWRL, keep your eyes peeled on http://freewrl.sf.net, and, please send in comments (both good and bad). We like to know how we're doing.
