2014年10月15日 · Now you should find yourself at the gdb prompt. There you can issue commands to gdb. Say you like to place a breakpoint at line 11 and step through the execution, printing the values of the local variables - the following commands sequences will help you do this: (gdb) break test.c:11 Breakpoint 1 at 0x401329: file test.c, line 11.

2014年8月11日 · Starting in gdb 7.0, there is reversible debugging, so your new favourite commands are: * reverse-continue ('rc') -- Continue program being debugged but run it in reverse * reverse-finish -- Execute backward until just before the selected stack frame is called * reverse-next ('rn') -- Step program backward, proceeding through subroutine calls. * reverse-nexti ('rni') -- Step backward one ...

2022年4月19日 · "miDebuggerPath": "C:\\msys64\\mingw64\\bin\\gdb.exe", The “program” is the program generated when building the project. I.e. the output from running the task as specified in Tasks.json. The miDebuggerPath is the path to gdb, the GNU gdb debugger.

2016年2月17日 · Normally when you run a program through GDB you can press Ctrl+C to interrupt it, e.g. if it gets stuck in an infinite loop and you want to get a backtrace. I'm debugging a program (xmms2d as it happens) but in this program only, when I press Ctrl+C it gets treated as if GDB was not running - the program shuts down cleanly and then GDB tells me ...

2012年4月11日 · GDB dashboard uses the official GDB Python API and prints the information that you want when GDB stops e.g. after a next, like the native display command. GDB dashboard vs GDB's TUI mode: more robust, as it just prints to stdout instead of putting the shell on a more magic curses state, e.g.:

2020年1月26日 · GCC can't do that but GDB (a debugger) sure can. Compile you program using the -g switch, like this: gcc program.c -g Then use gdb: $ gdb ./a.out (gdb) run <segfault happens here> (gdb) backtrace <offending code is shown here> Here is …

2018年7月20日 · In C, this would decay back to a pointer in most contexts except as the operand of & or sizeof, but gdb uses the array type directly to print the array. – R.. GitHub STOP HELPING ICE

2012年7月23日 · TODO: how GDB finds that file is the final mistery, it is not in my Python path: python -c "import sys; print('\n'.join(sys.path))" so it must be hardcoded somewhere? Custom classes. See how to define a custom toString method and call it at: Printing C++ class objects with GDB. Inspect specific elements in optimized code

2013年7月31日 · In case you want to see the local variables of a calling function use select-frame before info locals. E.g.: (gdb) bt #0 0xfec3c0b5 in _lwp_kill from /lib/libc.so.1 #1 0xfec36f39 in thr_kill from /lib/libc.so.1 #2 0xfebe3603 in raise from /lib/libc.so.1 #3 0xfebc2961 in abort from /lib/libc.so.1 #4 0xfebc2bef in _assert_c99 from /lib/libc.so.1 #5 0x08053260 in main (argc=1, argv=0x8047958) at ...
