Hi,
my program runs Lua scripts from multiple threads. It looks like this:
1.
In my host program:
...
lvm1 = lua_open()
...
lvm2 = lua_newthread()
...
2.
Start a separate OS-thread that does the following:
...
lua_getfield (main, LUA_GLOBALSINDEX, "main");
int lua_err = lua_qpcall(lvm2, main, 0, 0, 0);
if (lua_err)
{
script->FormatLuaErrMsg(lvm, lua_err);
return lua_err;
}
return 0;
Lua script code:
function main()
require "iuplua"
dlg = iup.dialog
{
iup.vbox
{
iup.button{title="Button Very Long Text", size="50x"},
iup.button{title="short", expand="HORIZONTAL"},
iup.button{title="Mid Button", size="50x"}
}
;title="IupDialog", font="Helvetica, Bold 14"
}
-- Show the dialog and run the main loop
dlg:show()
if (not iup.MainLoopLevel or iup.MainLoopLevel()==0) then
iup.MainLoop()
end
iup.Close()
end
3.
When the thread is finished, the following occurs:
lua_close(lvm1) // lvm1 = lua_open()
and then an error ACCESS VIOLATION occurs. Error occurred while releasing
resources in Lua sources freeobj(L, curr);
Got any ideas?
