In general, no.


Specific compilers may embed a version label in the object file. Our
compiler (Micro Focus Cobol) embeds a what string in the object which
you can display via


    what my_obj.o


The AIX C compiler also embeds a version string, though not in
"what(6)" format.


If you are on Unix, try


    strings -a -10 my_obj.o


and look for strings such as "version", "release" or synonyms, or
"d.d" (where d is a decimal digit).


If all else fails, try checking the relevant compiler documentation.

Away O Soul! hoist instantly the anchor!
Cut the hawsers - haul out - shake out every sail
Sail forth - steer for the deep waters only
Reckless O Soul, exploring, I with thee, and thou with me
For we are bound where mariner has not yet dared to go
And we will risk the ship, ourselves and all
