Re: Shared libraries and symbols
It's OK with me if the guidelines specify that shared libraries be stripped. Thanks Bruce
Re: Shared libraries and symbols
From: Michael Meskes [EMAIL PROTECTED] Can we strip shared libraries? Yes. There is a different symbol table for shared objects that you can print with nm --dynamic. Bruce

Bruce Perens writes: Yes. There is a different symbol table for shared objects that you can print with nm --dynamic. So could we please add this in the guidelines? I didn't check the guidelines on this but we should also ask the libraries (static and dynamic) to not contain debugging symbols. If this is already noted should I report it as a bug if I find some?

Re: Shared libraries and symbols
Hi Dominik, /lib/libc.so.5.4.4: no symbols This is most certainly a bug! Why? It works without a problem. I got this libc by using David's Debian files with HJ's sources. Try debug a dynamically linked binary using gdb and you will see lots of messages about loading symbols from the shared libraries ... circe:meskes 108) nm /lib/libc.so.5.4.4 /lib/libc.so.5.4.4: no symbols circe:meskes 109) ./t Segmentation fault (core dumped) circe:meskes 110) gdb t core GDB is free software and you are welcome to distribute copies of it under certain conditions; type show copying to see the conditions.

Reading symbols from /lib/ld-linux.so.1...done. #0 0x4006eeb4 in memmove () So where's the problem? I would prefer to keep the symbols in the libraries. As for the static libraries they have to be kept but the for the shared ones? Also I don't see any reason why debugging symbols are kept. I ran `strip -g` on my libraries and saved about 500K (sorry don't know the libraries that had the debugging symbols).

Shared libraries and symbols
Can we strip shared libraries? I don't know whether that's possible but I just found out that 'nm /lib/libc.so.5.4.4' (yes, I know this is not the Debian version) on my system gives: /lib/libc.so.5.4.4: no symbols However, almost all other shared libraries come with symbols, some even with debugging sysmbols (at least strip -g is able to reduce the library size). If these symbols are not needed I'd like to ask all libraries to be stripped since it saves an awful lot of disk space. If for some reasons the symbols are needed could anyone tell me why my libc works?
