ios - 问题理解链接器错误。缺少图书馆？

Question

我正在开发一个两年前完成的项目。我的想法是将它移植到 iPad Mini 和 iPhone 5 上。但我什至无法在 Xcode 4.5.2 上编译它，我猜它与它所针对的旧 iOS 有关。有人可以帮助我理解这个错误消息吗？

ld: library not found for -lgcov clang: error: linker command failed with exit code 1 (use -v to see invocation)

Answer 1

根据错误信息:

ld: library not found for -lgcov clang: error: linker command failed with exit code 1 (use -v to see invocation)

可能有两个问题:

1. 您没有 gcov 库
2. 您的 gcov 库与之前的位置不同

如果您根本没有 gcov 库，请安装它。

如果您有 gcov 库，请确保链接器可以看到它，请使用:

-Lpath/to/libgcov
