Does anybody outthere know how I can replace Routines in a shared library ? We would like to remove Suns gethost* Routines and replaces these with resolver-routines (Yes, I know that I can ftp such libraries at uunet, but as far as I know these libraries are 4.0 libs not 4.03. So all 4.0 bugs are still not fixed in these libs). Next thing I would like to know ist how I can create a .sa file from the shared library. thanx in advance -Torsten Torsten Beyer e-mail : tb@unido.uucp University of Dortmund,IRB ..uunet!unido!tb P.O.Box 500500 BITNET : tb@ddoinf6.bitnet D-4600 Dortmund 50, West Germany voice : +49 231 7552422

I would like to know what good/bad experiences users have had with shared
libraries? Are they appropriate for a research environment using C++ that
consists of lots of single user workstations and a central compute server?
Any serious performance hits? (Obviously, there are benefits at the OS
level for commonly-used commands.)
I currently have a set of 10 libraries distributed something like this:
Size: 205896 Heavy (All programs)
Size: 97576 ^
Size: 732310 |
Size: 145356 |
Size: 45406 Usage
Size: 668680 |
Size: 117300 |
Size: 46164 |
Size: 83052 v
Size: 125960 Light (Few programs)
and about 100 utilities that are run infrequently (a few times per
day). It seems to me the main benefit is to put heavily used stuff in
a shared library and leave the other stuff in a standard library. I am
worried about large programs having to resolve hundreds of references at
run-time and requiring a long time to startup and large amounts of
memory.

Is there a way to convert executables that are linked with shared libraries (to be loaded by ld.so when executing) into executables that do not use shared libraries (eg. with all library references resolved and the used lib functions loaded in the executable) ? If so, does there exists a program that performs this task ?
