In Linux environment? If you have GCC installed, you should have readelf executable. So you can try this

readelf --debug-dump=info binary_name | grep -A 2 'Compilation Unit @'

If on Mac OS X, you would use `xcrun dwarfdump -r0 binary_name`. – Jason Molenda May 04 '13 at 20:58

You could also use llvm-dwarfdump tool as below

llvm-dwarfdump -r 1 binary_name | head | grep Compile

Sample output

0x00000000: Compile Unit: length = 0x0004710b, format = DWARF32, version = 0x0004, abbr_offset = 0x0000, addr_size = 0x08 (next unit at 0x0004710f)
