If the next line is a function call, it steps OVER it (and does not go into the function). Similarly, print arr+10 would print 10 more than the element at position 2 in the arr array. For example, print *ptr would print the current value at the memory location held in ptr. Prints the result of the given expression using current variable values. Prints the current value of the given variable Runs your program from its current point of execution until it hits the next breakpoint Sets a breakpoint at the given function nameĮxecutes your program from the beginning, and lets it run until it hits your first breakpointĭisplays a graphical view of your code and highlights the line that will be executed next You can add breakpoints at any point – either before running the program in the debugger or in the middle of a debugging session. Sets a breakpoint at the given line number. Here is a summary table of the most common gdb commands: Command This can help us identify our error – we forgot to include a base case. Now we can see that we made a recursive call with a parameter of -1, which is clearly incorrect. This program is supposed to multiply together the numbers 1 * 2 * 3 * 4 * 5, but it has some problems: Suppose we have the following program, test.c. This tutorial to get gdb on your machine. If it’s not, click “New”, paste in the address you copied in the previous step, and click OK three times to dismiss each frame. Look to see if the location of your gdb.exe file is already listed – if it is, you don’t need to add anything. Click “Environment Variables.”, then find Path under System variables and click “Edit…”.
Click Start, type Environment variables, and select “Edit the system environment variables”). Next, add the location of your gdb.exe file to your Path (if it is a different location than your gcc.exe file). Copy the address where you find the gdb.exe file. The gdb.exe file should be in a \bin folder somewhere within the C:\msys64 folder - you may need to search for it.
It may be in the same location as gcc, which for me is C:\msys64\mingw64\bin, but it may be in a different location. Next, you will need to add the gdb.exe location to your Path.
