location_id for Facebook event creation -


i trying use location_id , retrieved current location, parameter facebook event creation, here code:

i have set authorization token , extended permission , , indeed returned valid location id; however, after plug location_id event creation parameter array, did not create event. (all other fields set through form).could help?

here code:

  try{     //default location     $event_url =  $my_url . 'create_group.php';     $event_location = $facebook->api('/me?fields=location');     $event_location_id = $event_location['id'];     echo $event_location_id;    }     catch(exception $e)    {    echo $e;    }    $params= array(      "name" => "[study group]".$_post['name'],     "description" => $_post['description'],     "location_id" => $event_location_id,     "start_time" => $_post['start_time'].$_post['time_zone'],     "privacy_type" => $_post['privacy_type'],     "end_time" => $_post['end_time'].$_post['time_zone'] );

here exception have:

exception: place or event attempted plan attend invalid. please try different place or event.

the exception solved in following way: change:

$event_location_id = $event_location['id'];

to

$event_location_id= $event_location['location']['id'];

the exception tells error wrong value of location id. , have debugged because of retrieved as

$event_location_id = $event_location['id'];

which should instead retrieved 

$event_location_id= $event_location['location']['id'];

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
