Python 自制GDB v。arm ONE eabi gdb

在多年使用Windows工具进行嵌入式开发之后，我决定回到我的Unix/Linux根目录，为OSX创建一个构建/调试环境。让我远离的是一个好的可视化调试器。我还喜欢Python和Ruby等语言。由于Python是一种我非常熟悉的语言，因此我希望为GDB编写Python扩展比在窗口之间跳转要好，因为在所谓的可视化编辑器中可以获得不同的信息

所以我有一个问题：在小牛时代，GDB不再被支持，而是被拯救了，我毫不费力地构建了GDB。我能够连接到OSX Segger JLink上的GDB服务器，而该服务器又成功地与无处不在的STM32F4发现评估板通信

启用了Python扩展。我可以重置并发出监视器命令来查看和戳内存。但无法加载我的文件：

ARM版本没有抱怨：

因此，我可以重建ARM版本以包含Python扩展，但为什么GDB/Homebrew不说ELF？

我被告知，由Homebrew构建的OSX版本GDB默认支持x86/64对象代码，ELF支持根本不存在。具体来说，它不是用target=arm none eabi构建的
