Linux gcc compiler output

Linux gcc compiler output

[Crumrine, Ray]

I'm trying to find out where in the header of the resulting file that is
created when gcc runs is the date / time of file creation and what format.
Can anyone help? I'm assuming it's probably there in some binary format. Any
help is appreciated.

Thanks,
Ray Crumrine

I'm not sure what you are asking. gcc does not normally put a
    timestamp in its output.

You can put code like this:

char const* cp= "Date: " __DATE__;
char const* cp2= "Time: " __TIME__;

in your program, and on most systems you can run strings on the
resulting binary, and see something like this:

$ strings a.out | grep 'Date\|Time'
Date: May  4 2004
Time: 07:04:56


If the output is an archive, and you
    have gnu binutils, you can use objdump -a to see the dates the
    individual members of the archive were added.

That's all I know about.
