GNU strip
discards all symbols from object files
objfile. The list of object files may include archives.
At least one object file must be given.
strip
modifies the files named in its argument,
rather than writing modified copies under different names.

--only-keep-debug
--strip-debug
and leaving the debugging sections.
The intention is that this option will be used in conjunction with
--add-gnu-debuglink
to create a two part executable. One a
stripped binary which will occupy less space in RAM and in a
distribution and the second a debugging information file which is only
needed if debugging abilities are required. The suggested procedure
to create these files is as follows:
foo
then...
objcopy --only-keep-debug foo foo.dbg
to
create a file containing the debugging info.
objcopy --strip-debug foo
to create a
stripped executable.
objcopy --add-gnu-debuglink=foo.dbg foo
to add a link to the debugging info into the stripped executable.
Note - the choice of .dbg
as an extension for the debug info
file is arbitrary. Also the --only-keep-debug
step is
optional. You could instead do this:
foo
to foo.full
strip --strip-debug foo
objcopy --add-gnu-debuglink=foo.full foo
ie the file pointed to by the --add-gnu-debuglink
can be the
full executable. It does not have to be a file created by the
--only-keep-debug
switch.
