Ok, here is the issue: I needed to include some custom-made material in Gazebo 1.9.5, so I added to my bashrc the following line: export GAZEBO_RESOURCE_PATH=~/home/user/user_gazebo_pkg/media:${GAZEBO_RESOURCE_PATH}. Then, when I try to run gazebo, the following error occurs:

Unable to find shader lib. Shader generating will fail.terminate called after throwing an instance of 'Ogre::ItemIdentityException' what(): OGRE EXCEPTION(5:ItemIdentityException): Cannot locate material called 'Gazebo/shadow_caster' in SceneManager::setShadowTextureCasterMaterial at /build/buildd/ogre-1.7.4+dfsg1/OgreMain/src/OgreSceneManager.cpp (line 5833)

Someone else having this issue? Is it forbidden to set GAZEBORESOURCEPATH manually? This is issue is also present in version 2.2!

============================UPDATE==============================

Ok, sourcing the setup.sh from /usr/share/gazebo-1.9 worked, the Ogre_Exception dissappeared. My initial problem remains, the materials could not be resolved: could not load material...

I set the resource path like I've specified earlier: GAZEBO_RESOURCE_PATH=~/home/user/user_gazebo_pkg/media:${GAZEBO_RESOURCE_PATH}

Inside the media folder i've got materials->scripts and textures folders, where I copied the files I intend to use.

===============================SOLVED=========================

I changed GAZEBO_RESOURCE_PATH=~/home/user/user_gazebo_pkg/media:${GAZEBO_RESOURCE_PATH} to: GAZEBO_RESOURCE_PATH=~/home/user/user_gazebo_pkg:${GAZEBO_RESOURCE_PATH}

and now it works !

It seems like gazebo overrides the PATH with default strings if not set. This defaults should be the same as the ones in gazebos setup.sh file (for binary install something like /usr/share/gazebo-1.9/setup.sh)

so you can try to either source the file before you run your command:

source /usr/share/gazebo-1.9/setup.sh

or add the path that's in there to your export statement(something like):

export GAZEBO_RESOURCE_PATH=/usr/share/gazebo-1.9:/usr/share/gazebo_models:/your/path/here

hope this helps...
