i checked format in http://jsonlint.com/ valid

from javascript when trying read length of data this

for (var = 1; <= data.table.length; i++)

data.table.length returning 1 , loop runs once only,i don't know how length of object array inside json data loop can continue till end.

please help

it's because table object contains array 1 element. objects you're looking for, try instead:

for (var = 1; <= data.table[0].length; i++)

then going inside first element table , you'll number of children inside.

hope helps!

edit

sorry, that's because objects don't have length property. please refer thread on stackoverflow, jquery ajax json response has length undefined , incorrect data

if want loop objects try this,

for (var obj in data.table[0])     console.log(obj) // object

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).
