Undefined symbols for architecture i386或者armv7: “_OBJC_CLASS_$_XXX

Undefined symbols for architecture i386:

“_OBJC_CLASS_$_XXX”, referenced from:

objc-class-ref in XXX

ld: symbol(s) not found for architecture i386

clang: error: linker command failed with exit code 1 (use -v to see invocation)

如果真机调试就是 undefined symbols for architecture armv7错误！

发生这种错误通常是project.pbxproj这个文件引起的，尤其在多人合作开发的时候，svn提交不规范可能导致project.pbxproj发生错误，导致文件的引用不在project.pbxproj文件中。

xcode项目import文件会根据project.pbxproj来查找，查找不到文件的引用则会有上述的错误。

解决方法点击工程，在主界面中点击Build Phases，根据提示信息“XXX”来判断缺少什么文件，一般如果缺少自定义的文件，XXX会是缺少的类名，那么就在Complie Sources中加入该文件。如果缺少类库，则在Link Binary With Libraries中加入该类库。

看着就非常复杂！

有这么多的link STL的错误。

其实，就是你编译静态库的时候使用不同版本的标准库， C++ Standard Library

那么如何fix掉这个issue呢？看下面这两张图！

如果你这两个在编译静态库和在使用静态库的app中设置的是一样的，应该就可以解决掉这个问题！

事实上，compiler default 足够了。

iOS出现 Undefined symbols for architecture armv7 std::basic_string<char, std::char_traits<char>

分类： iOS |2013-07-18 16:49 |42人阅读

今天，使用了第三方一个库，结果，出现，iOS Undefined symbols for architecture armv7 std::basic_string<char, std::char_traits<char>

注意：不是修改Build Setting里面的设置，而是添加一个libstdc++.dylib, 搞定！
