I've set two breakpoints
Error In Re-setting Breakpoint 1: Cannot Access Memory At Address
in the source, when I launch the debug session however I see this in the console output: Cannot insert breakpoint 6. Error accessing memory address 0x25a: Input/output error. Cannot insert breakpoint 7. Error accessing memory address 0x8: Input/output error. and my breakpoints are never hit. The application does run however. Any ideas on what the I/O errors mean?

Warning Cannot Insert Breakpoint 1
comment| 1 Answer 1 active oldest votes up vote 2 down vote accepted Any ideas on what the I/O errors mean? They mean that GDB (used by Eclipse CDT) tried to set breakpoints on address 0x25a and 0x8, and failed (there is no code at either of the above locations). Why GDB decided to set breakpoints there is impossible to say: you didn't provide any details about how you have set your breakpoints. share|improve this answer answered Jan 2 '13 at 23:44 Employed Russian 86.4k14118171 Thanks for the response. I cleared all my breakpoints then set them again (from within CDT) and they worked this time. No explanation for the previous problems. –fred basset Jan 4 '13 at 22:01 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

I'm trying to debug a C++ module across JNI from a JUnit. 1. I launch my "JUnit" debug config and successfully breakpoint immediately after my System.loadLibrary(mysharedlib). 2. I then cannot access memory launch my "C/C++ Attach to Application" debug config, which is defined as: - Application=Debug/libmysharedlib.so - Build config=debug - Debugger=gdb - Non-stop mode=off (although this setting makes no difference) This Attach to Application launches, I then attach it to javaw properly, and I see 13 suspended threads. 3. I then attempt to resume C++ thread #1 (state=suspended: user request) to no avail. - Entering "info break" from the gdb console correctly shows my breakpoint in the C++ code. Further, I can successfully display code in my C++ module, so I know I have debug info present. - Entering "c" from the gdb console gives: Warning: Cannot insert breakpoint 1. Error accessing memory address 0x2da6: Input/output error. 4. When I then attempt to resume the JUnit thread, I get the expected "org.eclipse.jdi.TimeoutException: Timeout occurred while waiting for packet 622. occurred resuming thread." as it appears all C++ threads are still suspended. The workspace/.metadata/.log yields messages like: !ENTRY org.eclipse.cdt.dsf 4 10005 2011-06-13 12:06:55.727 !MESSAGE Request for monitor: 'RequestMonitor (org.eclipse.cdt.dsf.concurrent.RequestMonitor@68446844): Status ERROR: org.eclipse.cdt.dsf.gdb code=10004 Failed to execute MI command: -exec-continue Error message from deb
