"Apple Mach-O(id)链接器"将外部库添加到项目时出错 [英] "Apple Mach-O (id) linker" error when adding external libraries to project

问题描述

我将FMDB添加到我的项目中，然后添加了框架libsqlite3.dylib和libsqlite3.0.dylib，但是仍然出现构建错误.如果我从项目中删除FMDB类，则可以正常构建.我还应该检查什么?

I added FMDB to my project then added the frameworks libsqlite3.dylib and libsqlite3.0.dylib, but I still get the build error. If I remove the FMDB classes from my project then it builds just fine. What other things should I check?

推荐答案

从项目中删除fmdb.m，就可以了.

Remove fmdb.m from your project and you will be fine.
