after stripping all debugging symbols in static lib, final link fails

[tvnaidu]

creating execuable file in Linux by linking some static libraries (to link ibxyz.a, using -lxyz option). if I strip all symbols in static library (strip -s libxyz.a), then if try to link again, then I gets lot of "undefined reference", can't I do strip on static library using below command?

strip -s xyz.a

Erm if you strip all symbols using -s then there will be no symbols left in the library including all the functions you are expecting the linker to find.

Looklike I ma using wrong one, I have to use -g option to remove debugging symbols.

why -S option available, it is not useful at all?

[Banfa]

It is eminently useful if you want to force a rebuild of your library from scratch.

Typically, strip is used on a final product like an executable or program. This removes all symbolic information from prying eyes. It makes no sense to do this to a library (unless you really want to rebuild it, like Banfa suggested).

-S might be the option you might want to use. It only removes debugging info.

Thanks. Let me commant that "strip" command right now, let me enable only for final release, right now I just tried whether it is working or not, since my exeuatble file is almost 1.8 meg size, when I do strip on all static libraries, I got down file size to 800K, but currently let me disable strip command.

but I have other thread, I have some issue with shared libs, I changed all to static libs, I created linux execuatble using -static option, somebody suggested not to use -static option at all, if I takeout that -static option, I can see segmentation fault.
