体系结构i386的未定义符号:"_ OBJC_CLASS _ $ _ ZipException",引用自:error

Question

我在我的项目中使用了几个'.o'文件,在编译时显示以下错误,

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

我在下面发布了错误日志

Ld /Users/deepak/Library/Developer/Xcode/DerivedData/app-bnwpvhpbrfdurbdgxucyddqyfosh/Build/Products/Debug-iphonesimulator/app.app/app normal i386

ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

最初,有更多的错误并通过导入libs.dylib框架解决了它们,

但仍有2个错误仍然存​​在.

编辑:我已经经历了流行的问题未定义的架构i386符号:_OBJC_CLASS _ $ _ SKPSMTPMessage",引自:错误,但该解决方案对我不起作用

有谁知道我哪里出错了？我是xcode的问题,任何缺少的库或链接的东西失败？

提前致谢

该错误消息说,未定义的符号被引用ZipFile.o,ZipReadStream.o和ZipWriteStream.o.这意味着您正在尝试在应用中使用Objective-Zip库.

未定义的符号是_OBJC_CLASS_$_ZipException.编译器@implemention ZipException在源文件中看到该指令时会生成此符号.

Objective-Zip库包含一个名为的文件ZipException.m,其中包含该@implementation ZipException指令.

最可能的解释是,您根本没有包含ZipException.m在目标中.检查你是否已经这样做了.如果你不知道如何,看看这个答案.

另一种可能的解释是,您ZipException.m可能会以删除@implementation ZipException指令或将其隐藏在编译器中的方式意外修改文件.检查您是否未修改该文件,并且该文件包含该@implementation ZipException指令.
