Android / GDB – 头痛 – 无法找到调试符号

2019年8月3日 186次阅读

GDB开始让我头疼. GDB的工作方式似乎有些奇怪.

obj / local / armeabi /包含项目中使用的所有.so文件的列表,这些文件未被剥离,以及一个名为objs-debug的目录,其中包含一堆.o和.od文件.

在启动ndk-gdb时,似乎没有任何.so文件被加载.

我试图手动更改gdb.setup文件,但显然当启动gdbserver时,文件被替换为自己的版本;)

libmylibary上的nm -a -C显示了大量的符号.

它似乎没有加载任何.so文件,甚至没有在objs-debug文件夹中查找.啊!

任何帮助总是非常感激.

最佳答案 似乎错误消息符号并不重要.在这种情况下,请确保使用-O0或-O1和-g -ggdb编译共享库,以帮助gdb在编译共享库后拾取这些调试符号.

如果你遇到问题(在gdb命令行上)’info sharedLibrary’,’where’或’backtrace’来帮助确定gdb是否真的能够找到它的位置.
