在编译osgearth的时候我已链接了minizip的头文件和zlibstat.lib的库文件

osgchina_allen

？？？

psj

楼主，你好，上述问题解决了吗？我也遇到与你类似链接错误，不知道如何解决，感觉是zlib有问题，重新编译了zlib，也不行啊，我用osg3.2.1+osgearth2.5+Qt4.8.6+vs2010，其它都编译通过了，就有上述链接错误，插件kMZ插件库没生成

恩  我已经解决了，我使用了最新的osg，这个版本异界不适用minizip了

请问楼主，你们编译的时候，3drparty的库，是osg官方下载的吗？，为什么我编译最新的无法加载影像图osgearth_map中的例子，显示的是白色的，是3drparty库版本太旧的原因吗？
