Re: [osg-users] Drawing a simple sphere...
Thanks Ulrich, I'm actually having a slightly different problem, which seems to using different compilers for OSG and my application. See: http://forum.openscenegraph.org/viewtopic.php?p=46918 I thought I'd try fooling around with optimization flags, since I've tried almost everything else. Thanks for your reply though.

Re: [osg-users] Drawing a simple sphere...
Hi Ulrich (et al), How did you change the optimization flags in your makefiles? Did you search and replace through them all? or is there a cmake variable / technique for doing this?

These days (the original thread is from August 2011) the only things I have to modify in the cmake settings (through ccmake) is the architecture (to x86_64 only, because of dependencies) and the location of the freetype library (from MacPorts).

Re: [osg-users] Drawing a simple sphere...
Are you able to run the OSG apps and examples? If so, why not compare how they are built with how you are building yours. IIRC, Bus errors are typically caused by a mismatch between the .lib stub libraries and the .so runtime libraries, so if you have been using multiple versions of OSG (or any other libraries that you link with), that's something you'll want to check. -Paul On 8/27/2011 9:31 AM, Yann Blaudin de Thé wrote: Hi again, I spent the last days trying to compile OSG and running my simple code, and nothing works.

Re: [osg-users] Drawing a simple sphere...
Hi,
I recall a post from some days ago, describing problems with the
llvm-gcc compiler and osg on lion. The app hang/crash on a call to cosf.
The solution was to switch to the gcc compiler.
Perhaps the same issue as yours?
cheers,
Stephan

Your best bet is probably to run it from gdb and see where it barfs.
When you say loading a .3ds works fine, is that through osgviewer or your
own application?

[osg-users] Drawing a simple sphere...
Hi,
I'm quite new to OSG, and I don't get why my (very (very)) simple code crashes :
[main.cpp]
#include osg/Shape
#include osg/ShapeDrawable
#include osg/Geode
#include osgViewer/Viewer
int main(int argc, char *argv[]) {
osg::Group* root = new osg::Group;
osg::Geode* geode = new osg::Geode();
geode-addDrawable(new osg::ShapeDrawable(new
osg::Sphere(osg::Vec3(0.,0.,0.), 1.)));
root-addChild( geode );
osgViewer::Viewer viewer;
viewer.setSceneData( root );
viewer.realize();
while( !viewer.done() )
viewer.frame();
return 0;
}
I run :
g++ -c main.cpp
and then
g++ -o sphere main.o -losg -losgViewer
So far, everything goes well. Then, when I type :
./sphere
the app crashes without displaying any sphere, and yielding :
Bus error: 10
But when I want to display a .3ds mesh, it works perfectly well.
I am under Mac OS X Lion (10.7), and I compiled OSG myself.
What's wrong? ;(
Please help
Thank you
