Hello, I'm trying to run the hello tutorial provided with Genode on my system and am having trouble understanding it's output. When I run ./core all I get is:
int main(): --- create local services --- int main(): --- start init --- int main(): transferred 17592186044415 MB to init int main(): --- init created, waiting for exit condition --- Quota exceeded! amount=4096, size=4096, consumed=4096 [init] upgrading quota donation for SIGNAL session [init] Could not open file "config" [init] Could not obtain config file [init] C++ runtime: Genode::Config::Invalid [init] void* abort(): abort called
and the system seems to be waiting indefinitely. Is there anything wrong I've done? Am I missing anything?
Thanks in advance for helping the beginners. - Pramod
Hello Pramod,
welcome to the list :-)

The log output states that you are missing the file "config" and also that "init" could not obtain its configuration. The config file is essential to bootstrap the Genode system. Otherwise, init (which is the first process comparable to Linux's init) does not know which processes to start and how to configure resources. So in your case, it just throws an exception (Genode::Config::Invalid) which is not catched and, therefore, just aborts.
You need to write the config file and put it into the bin/ directory
http://genode.org/documentation/developer-resources/client_server_tutorial#M...
Then, the following should work
cd bin; ./core
Have fun
hi, Thanks for the reply and sorry for taking so long to respond. Really sorry for my carelessness and asking you for help. It did work out but now I have a new problem. (This time I made sure I did no mistake ) Now I get the message: int main(): --- create local services --- int main(): --- start init --- int main(): transferred 17592186044415 MB to init int main(): --- init created, waiting for exit condition --- [init] Could not open file "ld.lib.so" Quota exceeded! amount=4096, size=4096, consumed=4096 [init] upgrading quota donation for SIGNAL session [init] timer: no route to service "CAP" [init] hello_server: no route to service "CAP" [init] timer: no route to service "LOG" [init] hello_server: no route to service "LOG" [init] hello_client: no route to service "Hello" [init] hello_client: no route to service "LOG"
So I took a look around in Genode site and decided to add few more lines to the config file. The lines I added were:
<route> <any-service> <parent/> <any-child/> </any-service> </route>
I added this to each process in config file. Then I get a different error message:
int main(): --- create local services --- int main(): --- start init --- int main(): transferred 17592186044415 MB to init int main(): --- init created, waiting for exit condition --- [init] Could not open file "ld.lib.so" Quota exceeded! amount=4096, size=4096, consumed=4096 [init] upgrading quota donation for SIGNAL session Quota exceeded: timer memory for slab: 1024 used quota: 66968 ds_size: 32768 sizeof(Ram_session_component): 408 quota_limit: 94208 Quota exceeded: hello_server memory for slab: 2048 used quota: 72088 ds_size: 167936 sizeof(Ram_session_component): 408 quota_limit: 94208 [init -> timer] C++ runtime: Genode::Thread_base::Stack_alloc_failed [init -> timer] void* abort(): abort called
Sorry for troubling you so much. But I'd appreciate any help. Thank you.

Hello Pramod,
please do not hesitate to ask questions. Without questions like yours, we won't be able to spot the weak points in our documentation, and improve them accordingly. :-)
So I took a look around in Genode site and decided to add few more lines to the config file. The lines I added were:
<route> <any-service> <parent/> <any-child/> </any-service> </route>
Apparently, the session routing is not explained in the hello tutorial. We might need to add the relevant bits there. Thanks for the hint.
Quota exceeded: timer memory for slab: 1024 used quota: 66968 ds_size: 32768 sizeof(Ram_session_component): 408 quota_limit: 94208 Quota exceeded: hello_server memory for slab: 2048 used quota: 72088 ds_size: 167936 sizeof(Ram_session_component): 408 quota_limit: 94208 [init -> timer] C++ runtime: Genode::Thread_base::Stack_alloc_failed [init -> timer] void* abort(): abort called
It looks like the quota defined for the timer and hello_server programs is too low. The message tells us that the timer wants to allocate a dataspace of 32K, but there is no room for this allocation within bounds of the available quota. For the hello_server, the issue looks similar. The hello tutorial suggests to assign 256K for both, which seems to be too rigid. Could you try increasing the values, let's say to 512K?
Thanks for your patience with exercising the tutorial. Good luck!
Norman
Thanks that works! regards Pramod
