Best way to strip off symbols

Question

Last week I released the Linux and windows version of an application.

And after the release we realized that the symbols were not stripped off, and my manager thinks

Answer 1

For the GNU toolchain, there exists a cool sleight of hand:

objcopy --only-keep-debug yourprogram ../somepath/yourprogram.dbg
strip yourprogram
objcopy --add-gnu-debuglink=../somepath/yourprogram.dbg yourprogram

Now you can zip the folder your program is in (or pack it into an installer or whatever), there will be no more debug symbols in it.
BUT : If you launch the debugger or if you run a tool like addr2line or obdump, the tool will (thanks to the debuglink info) automagically know where to find the symbols and load them.

Which is awesome, because it means you have the benefits of having symbols on your end, without distributing them to the user.
