macos - macOS Mojave 10.14.2 上的 gdb

问题描述

  1. 操作系统版本：macOS Mojave 10.14.2
  2. gdb：8.2.1（使用 brew install gdb 安装）

  3. 我成功地进行了代码设计

    codesign --entitlements gdb-entitlement.xml -fs gdb-cert $(which gdb)

  4. 我有这样的简单代码：

    int main(int argc, char *argv[]) { std::cout << "你好，世界" << std::endl; 返回0；}

  5. 然后 gdb 挂起

    zhifandeMacBook-Pro:cpp-quick-start zhifan$ g++ -g main.cpp

    zhifandeMacBook-Pro:cpp-quick-start zhifan$ gdb ./a.out

我的 gdb 一直挂在这里（[进程 11806 的新线程 0x2707]）。

我不能使用 8.0.1，因为问题未知加载命令 0x32

我还可以做些什么？

解决方案

好的，根据我过去两年使用 MacBook Pro 编码的经验。我从来没有成功让 gdb 正常工作。macOS 使用 Xcode Developer 工具进行编译。这些工具包括与 gdb 非常相似的 lldb。

这是一个可以帮助您做到这一点的网站。 https://lldb.llvm.org/lldb-gdb.html 这是一张直接展示gdb工具和lldb工具的图。希望这可以帮助。
