我的目标是使用库OSGEarth制作一个可以显示模型的MFC项目" openstreetmap.earth"。我完成了这个并且可以看到地球。但是每当我关闭项目时,vs2015中的输出窗口都说程序中存在内存泄漏。
这是窗口输出:
Detected memory leaks!

我检查了程序,发现当我删除这段代码m_Model = osgDB::readNodeFile(m_strModelName);
时,没有更多的内存泄漏。
void COSGEarth::InitSceneGraph(void)
{
// Init the main Root Node/Group
m_Root = new osg::Group;
// Load the Model from the model name,
//delete below line, no memory leak
m_Model = osgDB::readNodeFile(m_strModelName);
if (!m_Model) return;
// Optimize the model
osgUtil::Optimizer optimizer;
optimizer.optimize(m_Model.get());
optimizer.reset();
// Add the model to the scene
m_Root->addChild(m_Model.get());
}
我将 m_Model
定义为 osg::ref_ptr<osg::Node> m_Model
。这是智能指针。
为什么存在内存泄漏以及如何解决此问题?
答案 0 :(得分:1)
我相信这些报道&#34;泄漏&#34;是误报。请参阅此主题解释原因:
