Hello again, here is a small HOWTO for debugging Genode apps on Linux:
* The first thing to do is to interrupt Genode at a certain point as you cannot start core with gdb. So, if you want to debug an application you have to call 'wait_for_continue' from within your code. Somewhere in your code write something like: extern "C" void wait_for_continue(); void some_func_in_your_program() { wait_for_continue(); } This will cause your program to stall in the function above. * Compile your app * Start './core' from the command line * As mentioned before your program will stop in the 'wait_for_continue' function * Now find out the process id of your program, ('ps -efL | grep Genode') * Start gdb with 'gdb -p <Process ID from ps>' , this will attach gdb to the process * Switch to the Genode output console (where you started core) and hit 'enter', this will cause your program to leave the 'wait_for_continue' function * Switch back to GDB, you now may step and set breakpoints (note: Does not work with all gdb versions), inspect variables, ... . I hope this helps, Sebastian On 09/10/2010 05:34 PM, stephane frenot wrote: > Hello, > I have a problem while debugging genode with gdb. > > When starting gdb ./core it freeezes on 3 LWP. > > Is there a specific gdb configuration in order to reach sub services ? > > /stephane > -- > http://perso.citi.insa-lyon.fr/sfrenot > work here : http://tinyurl.com/2ts4xf > sleep here : http://tinyurl.com/33p2gt > play here : http://tinyurl.com/3yarjz > --- > Stephane Frenot > Université de Lyon, INRIA > INSA-Lyon, CITI, F-69621, France > > > ------------------------------------------------------------------------------ > Automate Storage Tiering Simply > Optimize IT performance and efficiency through flexible, powerful, > automated storage tiering capabilities.
