我正在开发一个调用本机代码的Android程序。该本机代码是segfaulting，因为通过android NDK进行调试并不是真的可行，所以我留下了一个如下所示的callstack（从ddms中捕获）。我的问题是，在将callstack中的内存地址转换为函数名之后是否可以手动运行，以便我可以看到这是segfaulting。

您应该在NDK bin目录中提供arm-eabi-addr2line的副本。您可以使用以下命令来使用它：
arm-eabi-addr2line -f -e /path/to/lib/with/symbols.so 0x001fb18a
这将遍历共享库中的调试符号以获取文件和行号信息。为了获得最佳结果，请将一个未删除调试内容的库交给它。

您需要生成地图文件。 map 文件包含可执行文件中的函数地址和内存位置。修改构建系统以生成映射文件。
从 map 文件中，您可以使用文本编辑器搜索地址。我曾经写过一个程序来找到绑定给定地址的两个符号。非常适合像你这样的环境。

您可以使用最新的ndks中包含的ndk-stack脚本。用法很简单：ndk-stack -sym“dir to objects with symbols”-dump“location to logfile”
