Embedded Programming with Modern C++ Cookbook

How to do it...

In this recipe, we will use the same environment and the same test application as in the first recipe. Refer to steps 1 to 9 of the Running your applications in the GDB recipe to build the application and copy it over to the target system:

1. We want to debug our runner function. Let's take a look at its content. In the gdb shell, run the program as follows:

(gdb) list runner,delay_ms

2. We want to see how the delta changes on each iteration. Let's set a breakpoint at the line:

14 if (delta > limit) {

3. Use the break 14 command to set a breakpoint on line 14:

(gdb) break 14

4. Now, run the program:

(gdb) run

5. Check the value of delta:

(gdb) print delta $1 = {__r = 0}

6. Continue execution of the program by typing continue, or ...
