 |
|
Edit: It has come to my attention that emerging OGRE with USE="doc" installs the Sample stuff into /usr/share/doc/ogre-1.0.1/Samples. Either way, the permissions are still wrong for a normal user, so my HOWTO is still useful (hoorah).
This is a setup HOWTO for OGRE, a cross-platform 3D engine. I feel that the installation of a typical OGRE build on Gentoo lacked some finesse, and (lacking the skill of making my own ebuild) have written a HOWTO for improving the OGRE installation, post-emerge.
Emerging OGRE
Crazy Eddie's UI, as well as nVidia's CG shader libraries are very useful tools, and the ebuild has USE variables for both of them, which I recommend using. Devil is used for image loading, and you will certainly run into problems with images and textures if you leave this out.
This takes care of unmasking OGRE and the one unstable masked dependency that it has:
| Code: | echo "=dev-games/ogre-1.0.1 ~x86" >> /etc/portage/package.keywords
echo "=dev-cpp/libglademm-2.2.0 ~x86" >> /etc/portage/package.keywords
USE="cegui cg devil opengl sdl" emerge ogre
(optional, if you want OGRE-specific USE variables) echo "dev-games/ogre cegui cg devil opengl sdl" >> /etc/portage/package.use
|
Getting the extras
While the ebuild (currently 1.0.1) is up-to-date, the problem is that the free stuff they give you (the meshes, materials, etc.) aren't installed anywhere. My solution was to re-use the distribution tarball, unpack it into a directory, and copy all of the files in Samples/Media to /usr/share/OGRE.
| Code: | (run as root)
mkdir /usr/share/OGRE/Media
mkdir /tmp/ogre (I like working with stuff in /tmp, this is optional)
cd /tmp/ogre
tar xjf ogre-linux_osx-v1-0-1.tar.bz2
cd ogrenew
cp -R Samples/Media /usr/share/OGRE/Media
chmod -R 755 /usr/share/OGRE/Media
|
This is for the GTK window used in the OGRE application, which prompts you for a resolution, renderer, and fullscreen/window. The OGRE logo is not displayed if it is not found in /usr/share/OGRE/Media.
| Code: | mv /usr/share/OGRE/Media/materials/textures/ogrelogo-small.jpg /usr/share/OGRE/Media
|
Demos
The demos can be compiled if you like, with the following:
| Code: | ./bootstrap
./configure (zziplib may be required, just emerge zziplib)
cd Samples
make
|
The demos will be placed in Samples/Common/bin. Edit the plugins.cfg file so that
| Code: | PluginFolder=/usr/lib/OGRE
|
Clean up hard-coded files
Edit resources.cfg and replace every instance of ../../ with /usr/share/OGRE/
(there is likely an easy combination of tools to replace these, but I don't know much BASH scripting. Feel free to let me know and I will update with an equivalent one-liner).
At this point, all of the hard-coded links to the various resources have been dealt with, and can be stored later, just in case.
| Code: | cp *.cfg /usr/share/OGRE/Media/ (or wherever you want)
|
Feel free to poke around in the ogrenew directory for documents and whatnot, or clean it up with:
| Code: | rm -fr /tmp/ogrenew

You need an update of the post. The new ebuild makes all the extra things you explain
