You didn't say what platform you're debugging, how you're running GDB, or anything else - one of those is to blame. -- Daniel Jacobowitz CodeSourcery ^ permalink raw reply [flat|nested] 6+ messages in thread

What system are you running GDB on? How are you running GDB?

You should not have to do anything. Don't mention the shared library explicitly to GDB - it doesn't need that. Just load the real application that you want to debug and run it. You should be able to set a breakpoint in the shared library. If you are using an old version of GDB, upgrade to the latest release. -- Daniel Jacobowitz CodeSourcery ^ permalink raw reply [flat|nested] 6+ messages in thread
