[osg-users] osgLua and osgShadow
Hello,
while loading osgShadow with osgLua (which uses osgIntrospection and
osgWrappers):
script->enable("osgShadow");
I get a segfault. This happens in 2.8.2 as in trunk. While I didn't properly
investigate this, I should still mention for those interested that the crash
can be avoided by suppressing the problematic ConvexPolyhedron object. Add the
following to src/osgWrappers/genwrapper.conf and rebuild the wrappers:
suppress reflector "osgShadow::ConvexPolyhedron"
I may sure about this, but if this is not osgLua specific, perhaps it could be
put in trunk until better solution come along.
Best regards,
Marko

Yes please :) send them to me :) I've switched to mac (again) and I'm trying to make osgLua work, with very little time, but trying to catch up with the current OSG trunk. The RTTI problem, apart from the LD_GLOBAL, and the linker flags ( -Wl,-E ).. I can't tell what's going on sorry. Cheers, Jose-Luis. -- Jose L.

Re: [osg-users] osgLua?
Hi Jose-Luis, be assured I seen these messages before and also did the whole patches/linker flags etc. pp. that were suggested there. Still, the RTTI is stripped - so *nix is not going to work. Admittetly, I updated the osgLua sources in an intree version and added my own copy of Lua 5.1.4 into the buildsys (with the patch). Again, I checked that in the whole chain mentioned libs are being compiled with these flags. Its a pitty that this is been "ignored" by the Lua developers - I can't see why it is so outragous difficult to add this options. I will try to investigate in more depth - after all this is a very specific use-case. Are you still working on osgLua? I can flick you a few patches that might fix a couple of problems.

Re: [osg-users] osgLua?
No, not from Lua (or I guess a lua interpreter) itself - I have a wxWidgets application which loads various plugins and one of them is a based around osgLua - thus, lua_open etc pp should happen in that context.

[osg-users] osgLua
Hello,
I've a problem with osgLua.
Is it always maintained ?
For the moment, I just want to test the osgLua examples :
osg::Group* group = new osg::Group;
osg::Group* root = new osg::Group;
try {
group->addChild(root);
osg::ref_ptr script = new osgLua::Script();
script->enable("osg");
script->set(root, "root");
script->loadFile("/home/julien/workspace/TestLua/src/test.lua");
} catch (osgLua::Exception & e) {
std::cout << e.what() << std::endl;
}
and the test.lua provided with osgLua :
local root2 = osg.Group()
local geode = osg.Geode()
local shape = osg.ShapeDrawable()
shape:setShape( osg.Sphere(osg.Vec3(0,0,0),15) )
geode:addDrawable(shape)
root:addChild(geode)
-- we will now load osgText from the script
osgLua.loadWrapper("osgText")
text = osgText.Text()
text:setCharacterSize(4)
text:setPosition(osg.Vec3(0,0,18))
text:setAxisAlignment(osgText.Text.AxisAlignment.SCREEN)
text:setAlignment(osgText.Text.AlignmentType.CENTER_BASE_LINE)
text:setText("Hi all from osgLua!")
text:setColor(osg.Vec4(0.9,0.8,0.2,1.0))
geode:addDrawable(text)
The result :
/TestLua/src/test.lua:9: [/home/julien/OSG/osgLua/src/osgLua/Value.cpp:260]
ype `PN3osg5GroupE' is declared but not defined
I have liked all the osg and osgLua libraries, I don't understand...
Someone has an idea ? Thank you

[osg-users] osgLua and my own classes
Hi all, I want to use my own C++ classes in addition to those of OSG in my Lua scripts and I read in the README of OsgLua : "osgLua can also be used to access your own reflected classes (with osgWrapper)" but I am wondering how to do that, there is no example. Must I parse my classes with genparser ? And after ?
