在网上搜索我发现这是从 XC3 传递到 XC4 时的典型错误.也许图书馆没有更新.但是你看到的那个文件 .a 似乎是不可编辑的.

Searching on the web I found that this is a tipical error when passing from XC3 to XC4. Maybe the Library isn't updated. But that file .a that you see there seems to be uneditable.

推荐答案

已解决.必须加载 3 个框架:libXML、Security 和 libz.

Solved. Have to load 3 frameworks: libXML, Security and libz.
