在网上搜了一下，说是osgd.dll后于mfcXXd.dll释放，导致mfc误认为osg中全局变量没有释放，并给出了解决办法：
i) in the General tab, switch "Use MFC in a shared DLL" to "Use Standard Windows Libraries"
ii) in the C/C++/Preprocessor tab, add _AFXDLL to the preprocessor definitions
iii) in the Linker/Input tab, add mfc71d.lib anywhere before osgd.lib
可是我在VC2010中按那三步修改之后，没向OSG中添加任何节点，仍然存在内存泄露：
- Detected memory leaks!

请问在VC2010里要怎样才能解决OSG内在泄露的问题呀？
另外，还想问两个问题：
1、我的OSG编译时使用了UTF-8支持，那么在osgMFC中是不是也必须设置“使用 Unicode 字符集”？如果设置成“使用多字节字符集”会出现什么问题吗？
2、网上说通过上面的三步修改Debug设置后，必须设置“使用多字节字符集”，如果设置“使用 Unicode 字符集”则会报error LNK2019的链接错误。怎样解决在“使用 Unicode 字符集”时的链接错误呀？
请高手帮帮忙啊！不胜感激。 |
