Question

我正在尝试在osx 10.11上安装一个库但是当我使用cmake时，它会打印下面的输出。这在过去是有效的（就像昨天一样），但从那时起似乎出现了问题。我找了一个答案，但似乎找不到任何有用的东西。我的Xcode和Xcode命令行工具都是最新的。我的cmake是最新的。我尝试卸载并重新安装它无济于事。我已经测试了c编译器，据我所知它应该正常工作。我的openssl也是最新的，我尝试重新安装它也没有成功。我的Clang版本是7.0.0（clang-700.0.72）。我很遗憾可能是显而易见的事情。任何想法将不胜感激。

$ pwd
<*current directory*>
$ mkdir build
$ cd build
$ cmake ..

修改简单的重启似乎解决了它。我应该首先尝试的明显答案。抱歉浪费你的时间

Answer 1

错误为ld: can't map file, errno=22 file '/usr/local/opt/openssl/lib' for architecture x86_64。在我看来，这是一个目录，而不是一个文件。您可以在上面的行上运行cmake命令，并尝试在前面添加-L。

Cmake不工作。 C编译器失败
