/ usr / bin / ld：找不到-lc ++ [英] /usr/bin/ld: cannot find -lc++

问题描述

我正在跟踪有关在当到达执行sh build.sh的步骤时，出现找不到-lc ++ 错误。

I am following a tutorial on building an audio classifier here and when reach to the step where I run the sh build.sh I get the cannot find -lc++ error.

请注意，任何

推荐答案

替换 clang 由 clang ++ 或 g ++ 表示。然后 -lc ++ 变为自动

Replace clang by clang++ or g++. Then -lc++ becomes "automagically" linked.

当然，花几天时间阅读 GCC的文档和 C语（以及 ld 的 binutils ；因为 clang ++ 和 g ++ 正在运行 ld ）。请仔细阅读有关调用GCC 的信息。 g ++ （以及 clang ++ ）的程序参数顺序很重要。

Of course, spend a few days reading the documentation of GCC and of Clang (and of ld from binutils; since both clang++ and g++ are running ld). Read carefully about invoking GCC. The order of program arguments to g++ (and also to clang++) are important.

由于您使用的是 GNU make ，因此您显然需要花一天的时间阅读其文档

Since you use GNU make, you obviously need to spend a day reading its documentation.

PS。预算一下阅读文档的一周工作。

PS. Budget perhaps a week of work in reading documentation.
