Hi Scott,
This helped me to move forward, still I have problems. Gazebo gets killed
by SIGSEGV right after start. I tried to track down this using valgdind,
to my surprise, it works fine started with valgrind! (unfrotunately, this
is not an workaround: everything works slower with valgrind). I started
this with strace and it says:
stat64("~/psg3/share/gazebo/Media/materials/textures/grey_play_button.png",
{st_mode=S_IFREG|0644, st_size=1182, ...}) = 0

Looks like check for NULL pointer is missing somewhere.

Edit your ~/.gazeborc file and set orgePath to "/usr/lib/OGRE". You
will need to do this every time you reinstall gazebo.
This only happens on my Gentoo box, never tried to hunt in down though.

Hi Paul,
To get rid of the recursive_mutex problem remove the "threads" use
flag from ogre and reemerge ( apparently I hit this a long time ago
and forgot a about, but its in my notes ). You have to do an emerge
-aC ogre before emerging again, during my reemerge it sometimes tries
to link to the previous ogre install. Since this ebuild uses DeViL
and not Freeimage, some of my textures do not load correctly. I
typically use an overlay of ogre 1.7 with freeimage for gazebo stuff.
Hi Scott,
Setting -threads for ogre did the trick and problem with assertions is
now gone, unfortunately, still I cannot run Gazebo on that Gentoo box.
I compiled freeimage and installed globally in /usr/local/lib. Then I
unmerged ogre and emerged it again like that:
EXTRA_ECONF="--enable-freeimage" emerge ogre
This configure option enables freeimage which results in disabling DevIL.
Then I compiled gazebo once again. Result is:
Gazebo multi-robot simulator, version 0.10.0

Any suggestions for that?
