	collectgarbage question. by Taesoo Kwon :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Hi, I am using luabind-0.8.1, lua 5.1.4, and VC2005. I have a strange bug; collect garbage doesn't work in the following simple code. ----------------------------------------------------------------------- test1.lua -> Garbage collection doesn't work. (the dtor of VRMLloader class is not called.) do local skel=VRMLloader("aa.wrl") skel.dofInfo:setFrameRate(30) end collectgarbage() ----------------------------------------------------------------------- test2.lua -> Garbage collection works. (dtor called) do local skel=VRMLloader("aa.wrl") end collectgarbage() I have no idea what could cause the difference. Has anybody observed similar situation? ----------------------------------------------------------------------- binding: class VRMLloader: public MotionLoader { public: MotionDOFinfo dofInfo; VRMLloader(const char* vrmlFile); virtual ~VRMLloader() { printf("dtor called");} ... }; luabind::class_<VRMLloader, MotionLoader>("VRMLloader") .def_readwrite("dofInfo", &VRMLloader::dofInfo) .def(luabind::constructor<const char*>()) Thanks. ------------------------------------------------------------------------------ Come build with us!

	Re: collectgarbage question. by Taesoo Kwon :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message I am sorry. This wasn't a bug but a feature of lua 5.1.4. I had to add one more collectgarbage() call. do local skel=VRMLloader("aa.wrl") skel.dofInfo:setFrameRate(30) end collectgarbage() collectgarbage() -- two cycles are needed.

Learn more about Nabble's security policy. have you tried collectgarbage("collect") to perform a full garbage collection cycle? I'm not even sure what it does without an argument: http://www.lua.org/manual/5.1/manual.html Von: Taesoo Kwon <taesoobear@...> An: luabind-user@... Gesendet: Mittwoch, den 23.

	Re: collectgarbage question. by Taesoo Kwon :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Yes, I have. It gave the same result. A single collectgarbage call was not effective using any of the options. So I thought this may be what they call incremental garbage collection.
