Order by on String's substring in Linq -


i have date field convert value of database datetime string format("dd-mmm-yyyy"), need perform sorting string date field, seems when have been doing sorting, working , checking date, not month not year. when data in date format (database):

2012-01-29 2011-01-01 2013-03-28

so sorted 

2013-03-28 2012-01-29 2011-01-01

but sorted: 29-jan-2012 28-mar-2013 01-jan-2011

so want apply orderbydescending-> by-> on, need split string end, there way around? doing:

list<c> lst=lst.orderbydescending(d=>d.tdate.substring(d.tdate.lastindexof('-').tolist();

how this,

list<string> lst= new list<string>{"29-jan-2012", "28-mar-2013", "01-jan-2011","2011-01-01","2013-03-28"}; lst.orderbydescending(x=>datetime.parse(x));

in sample should be,

lst.orderbydescending(x=>datetime.parse(x.tdate))

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).
