Can a cursor move away from the GDB prompt?
In place of this behavior, the cursor can move anywhere in the emacs buffer even outside of the regular gdb prompt (which I find totally useless for my purpose). Is there a way to force gud to take the Up and Down keys as get backward and forward in the command history. And, is there a way to prevent the cursor to move away from the gdb prompt ?
How to execute the next line of code in Gud?
Execute the next single line of code ( gud-step ). If the line contains a function call, execution stops after entering the called function. Execute the next single line of code, stepping across function calls without stopping inside the functions ( gud-next ). Execute a single machine instruction ( gud-stepi ).
Which is the next stack frame in Gud-GNU?
Select the next inner stack frame ( gud-down ). This is equivalent to the GDB command ‘ down ’. Continue execution to the current line ( gud-until ). The program will run until it hits a breakpoint, terminates, gets a signal that the debugger is checking for, or reaches the line on which the cursor currently sits.
How to set a breakpoint in Gud interaction buffer?
Set a temporary breakpoint on the current source line, if any ( gud-tbreak ). If you use this command in the GUD interaction buffer, it applies to the line where the program last stopped. Select the next enclosing stack frame ( gud-up ). This is equivalent to the GDB command ‘ up ’.
How is the execution of a program affected by GDB?
The execution of a program is affected by certain information it receives from its superior. GDB provides ways to specify this information, which you must do beforestarting your program. (You can change it after starting your program, but such changes only affect your program the next time you start it.)
How do I request debugging information from GDB?
To request debugging information, specify the `-g’option when you run the compiler. Many C compilers are unable to handle the `-g’and `-O’options together. Using those compilers, you cannot generate optimized executables containing debugging information.
How to control which shell is used in gdb?
If a shell is available on your target, the shell is used to pass the arguments, so that you may use normal conventions (such as wildcard expansion or variable substitution) in describing the arguments. In Unix systems, you can control which shell is used with the SHELLenvironment variable. See section Your program’s arguments. The environment.
