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.
Treat the original objfile as a file with the object code format bfdname, and rewrite it in the same format.
would cause strip to only keep symbols that start with the letters “fo", but to discard the symbol “foo".
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:
1.<Link the executable as normal. Assuming that is is called> “foo” then...
1.<Run “objcopy --only-keep-debug foo foo.dbg” to> create a file containing the debugging info.
1.<Run “objcopy --strip-debug foo” to create a> stripped executable.
1.<Run “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:
1.<Link the executable as normal.>
1.<Copy “foo” to “foo.full">
1.<Run “strip --strip-debug foo">
1.<Run “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.
Read command-line options from file. The options read are inserted in place of the original @file option. If file does not exist, or cannot be read, then the option will be treated literally, and not removed.
Options in file are separated by whitespace. A whitespace character may be included in an option by surrounding the entire option in either single or double quotes. Any character (including a backslash) may be included by prefixing the character to be included with a backslash. The file may itself contain additional @file options; any such options will be processed recursively.
