Problem here is that<br/> my usual test-run starts in Python-code (as a Jython-run), then enters Java code<br/> and finally enters a C-shared lib via JNI and also goes through two more C-shared libs<br/> via dynamic loading. I would like to track breakpoints in the last two shared C-libs.<br/> <br/> It turned out that each of these steps requires notable tweaking with configuration.<br/> <br/> For example there are guides how to debug CPython+native C-code with GDB, how to debug<br/> Java code with native JNI-lib, how to debug C-code that steps into other libraries by<br/> dynamic loading (this one is said to require GDB-config that is not possible via<br/> Eclipse GUI). However, none of these covers my issue completely.<br/> <br/> Now my question is, whether there is someone around on this list who has already done<br/> something like this. Developing JNI-bindings intended for Jython should be not such a<br/> rare use-case. Does someone have experience in debugging such things in Eclipse?<br/> <br/> I would appreciate any help or guidance on this topic.<br/> <br/> <br/> Currently my best guess would be the following way:<br/> I could try to start my test-run as a pure Java-Application<br/> that passes the Python-file somehow to the Jython interpreter<br/> (thus not using PyDev at all).<br/> Then I could try to apply the howto for JNI/native code GDB and<br/> hope that it somehow covers the way through dynamically loaded<br/> libs.<br/> Is there a better, i.e. more "right" way to do this?<br/> </blockquote> <div> </div> Hi Stefan, <div> </div> <div>Usually in this situation what I do is start one of the debuggers regularly and attach the other one(s) through remote debugging (In PyDev there are instructions at <a href="http://pydev.org/manual_adv_remote_debugger.html" target="_blank">http://pydev.org/manual_adv_remote_debugger.html</a> -- there should be counterparts for the other languages).</div> <div> </div> <div>Cheers,</div> <div> </div> <div>Fabio</div> </div> </div> </div> ------------------------------------------------------------------------------ Android apps run on BlackBerry 10 Introducing the new BlackBerry 10.2.1 Runtime for Android apps.
