Newb Problem: Plugins not loading...

Postby jyurkiw » Sat Feb 25, 2012 9:25 am

I'm going through the Madmarx tutorials and I'm having issues loading plugins. Basically, Ogre isn't loading them. Any of them (so far as I can tell).

If someone could point out what I'm doing wrong, it would be appreciated.

Code to follow...

Ogre version is 1.7.4 compiled from source. System is Ubuntu Linux, AMD quad core ~3gig, 8 gigs ram, ATI 5770 video card. IDE is eclipse, but I've been executing from both eclipse and a terminal.
While I'm following MadMarx, it's not his code. I can't stand his coding style (the bracketing makes me want to punt a kitten. Purely personal preference) so I'm just using it as a guide. All the Ogre samples run at 60fps barring the Terrain sample when I change shadow types. The program compiles fine, but when I execute nothing happens (ready gets set to false in setupRenderSystems() so no initialization happens).

Ogre isn't loading any plugins, so I'm not getting a RenderSystem which means I can't initialize Root.

OMG...I figured out what it was.

I thought that my plugins directory was /usr/local/lib because it has a number of ogre .so's in it. However this is not the case. Yes, those are shared libraries, and are quite important for linking when you build, however the actual Plugins are in /usr/locl/lib/OGRE one directory down. Soon as I changed the PluginFolder= line in my plugins configuration file from PluginFolder=/usr/locl/lib to PluginFolder=/usr/local/lib/OGRE it worked!

...I knew it was something simple.
