无法在Mac的可视代码中调试C++

Question

我的环境：

$ clang++ --version
Apple LLVM version 10.0.1 (clang-1001.0.46.4)
Target: x86_64-apple-darwin18.7.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

Visual Studio信息：

Version: 1.43.1
Commit: fe22a9645b44368865c0ba92e2fb881ff1afce94
Date: 2020-03-18T07:01:41.240Z
Electron: 7.1.11
Chrome: 78.0.3904.130
Node.js: 12.8.1
V8: 7.8.279.23-electron.0
OS: Darwin x64 18.7.0

launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "MyProject",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/diffusion/run",
            "args": [],
            "stopAtEntry": true,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "setupCommands": [
                {
                    "text": "-enable-pretty-printing"
                }
            ]
        }
    ]
}

我可以很好地运行/编译C++文件。我甚至可以这样运行GDB：

$ sudo gdb diffusion/run
GNU gdb (GDB) 8.3.1
Reading symbols from diffusion/run...
Reading symbols from /Users/me/project/diffusion/run.dSYM/Contents/Resources/DWARF/run...
(gdb) break color
Breakpoint 1 at 0x1000024d6: file diffusion/render.cpp, line 21.
(gdb) condition 1 depth==1

gdb需要sudo，否则Mac会让你使用do some scary code-signing stuff，但除此之外一切都很好。

问题是，当我启动(点击F5)时，我看到以下内容：

Unable to start debugging. GDB exited unexpectedly with exit code 134 (0x86).

并且调试失败。如何正确设置它以在VSCode中调试C++代码？

Answer 1

你有没有试过禁用csrutil？虽然gdb会尝试写一些临时的东西，但默认情况下，macOS会限制应用程序写入根文件夹，所以它可能无法做到这一点。我也遇到过类似的问题，我禁用了csrutil，但它已经消失了。你可以尝试同样的方法。

祝好运。
