我知道有一个类似在那里。但我认为这个问题是不同的。GDB的腐败堆栈问题,不显示功能和行号
我使用gdb-cross-aarch64
来分析arm arch64设备上生成的转储核心文件。
我的命令行是这样的:
gdb-cross-aarch64 /path_to/gst-launch-1.0 /path_to/core.2135
和gst-launch-1.0
是取决于LIB libOmxCore.so
共享。
这里是gdb

Do you need "set solib-search-path" or "set sysroot"?

如上所示,我已经设置在gdb的sysroot
,和在libOmxCore.so
和gst-launch-1.0
符号由gdb
读取。
但我仍然无法通过gdb
看到有效的堆栈回溯。
我很确定signal SIGABRT
是libOmxCore.so
引起的。
我在这里做错了什么?或者我还应该做什么?
谢谢你
谢谢@tofro。 “我非常确定信号SIGABRT是由libOmxCore.so引起的” 因为我故意在libOmxCore.so函数中设置了“assert(0)”。因为我想指导自己如何使用'gdb'。 – Alan
