【问题描述】：
很长一段时间以来，我一直在尝试在运行 macOS Catalina 的 MacBook Pro 上编译和运行 c 程序，我尝试使用 cc、gcc 和 clang 进行编译，编译似乎工作得很好，但每次我运行.out 文件我的 Mac 冻结，我无法 control+c 退出应用程序，即使我终止终端，finder 应用程序仍会出现问题（它完全停止响应），所以为了解决问题，我必须完全关闭计算机，然后通过电源按钮再次打开。 我尝试过的每个程序都会出现这个问题，包括“hello, world”程序。
我用gcc -v -o demo demo.c 编译了一个最小的测试，输出是：

【问题讨论】：
-
即使使用“Hello World”程序也能做到这一点？ “问题仍然存在于 finder”，这是什么意思？请edit详细说明。
-
用
gcc -v -o helloworld helloworld.c编译一个“helloworld.c”并将输出粘贴到这里，也许我们可以看到一些可疑的东西。 -
为了完整性：
int main(void) { puts("Hi"); return 0; } -
在 Google 中搜索您抱怨
ignoring nonexistent directory "/Applications/Xcode.app/...的消息我找到了 Can't compile a C program on a Mac after upgrading to Catalina 10.15。 -
谢谢@DavidRanieri，你解决了我的问题。
