How to Resolve Assembly Code Stepping Issues While Debugging Go Programs in GoClipse?

Debugging Go Programs with GoClipse: Assembly Code Stepping Woes

Are you struggling to debug Go programs using GoClipse and encountering assembly code stepping issues? Let's delve into this dilemma and find a solution.

Upon setting breakpoints in your Go program, you might notice that the debugger steps through assembly code rather than Go code. For instance, a breakpoint set on the line "responses := []*HttpResponse{}" could lead to the debugging of "rt0_darwin_amd64.s". This behavior can be puzzling if you're unfamiliar with assembly.

The Root of the Problem

The Debug view in Eclipse should display a stack trace. If it shows a trace similar to "main() at rt0_darwin_amd64.s:15", you have encountered the issue. The debugger is stopping at the internal runtime "main" function, which is written in C.

Solution: Configuring Launch Options

To resolve this problem, adjust the launch configuration options as follows:

1. In the Run dropdown menu, select "Debug Configurations."
2. Modify the launch configuration for your Go program.
3. Navigate to the "Debugger" tab.
4. In the "Breakpoint Options" section, ensure that the "Stop on main, if debugging enabled" option is unchecked.

Alternative Option: Stepping Over the Runtime Main

If you're comfortable with assembly code, you can continue debugging by stepping over the runtime main. Simply press F8 (Run/Resume) to bypass this initial step and proceed with debugging your actual Go code.

Conclusion

By understanding the source of the assembly code stepping issue and adjusting the launch configuration options, you can effectively debug Go programs using GoClipse. Remember, if you encounter this behavior, ensure that you're pausing at the correct main function and not the internal runtime main.
