Why does Eclipse CDT ignore breakpoints?

Question

My problem is that I set some breakpoints in my code and some of them aren\'t working. In some places it complains about \"Unresolved Breakpoint\".

Does anyone have

Answer 1

I have found that sometimes switching the referred Process Launcher from "GDB (DSF) Create Process Launcher" to "Standard Create Process Launcher" has fixed this problem for me. Other times, just deleting all breakpoints and restarting Eclipse does the trick.

Answer 2

Make sure the breakpoint type is correct. For C/C++ it's a tiny blue dot. If it looks like anything else, chances are the breakpoint type is incorrect. I would try to close the file, right click on it -> open with -> C/C++ Editor. This worked for me.

Answer 3

I had a similar issue with GDB. It seems that it was caused by identical source code filesnames even if they have different paths. I renamed the duplicates and GDB worked just fine after that.

Answer 4

"Unresolved Breakpoint" just means that GDB did not find code location corresponding to the file and line on which you attempted to set a breakpoint.

Are you trying to stop in a constructor?

If so, you are likely seeing this cently fixed GCC bug.

Answer 5

i had the same problem,

1.- Removed the breakpoints. 
2.- Restart eclipse 
3.- Clean the project by using project -> clean 
4.- Add again the breakpoints and start your debugging.

This solved my issue.

Sometimes optimizations will cause breakpoints to be skipped as well. Make sure you're compiling with -O0
