Recompiling and uninstalling existing applications
Hi everyone,
I'm new-ish to Unix outside of being a basic user in the past. So some background on my experience level when asking this question.
My current laptop, running OS X 10.5, had Apache and PHP installed when I bought it. However I need to recompile these now to add features which weren't included 'out of the box'.
Questions:
- Do I need to do anything to 'uninstall' these existing versions of the software before the recompile?
- Do I need to delete the binaries/libraries/other directories/etc of a program I am going to be recompiling (if this isn't answered by the above question) or will this automatically be taken care of?
- How can I make sure I don't leave anything 'hanging around' when I do uninstall a program? Or recompile?
- What resources can I read to learn more about all of this and related?
Thanks!
Charles

Hello,
There is a need to link a new dynamic library to a big number of exes.
Unfortunately, I cannot recompile/link all these exes against the new library.
Is there any way to link an existing executable with the new library?

bos_uninstall
BOS_UNINSTALL(8) AFS Command Reference BOS_UNINSTALL(8)
NAME
bos_uninstall - Reverts to the former version of a process's binary file
SYNOPSIS
bos uninstall -server <machine name>
-file <files to uninstall>+ [-dir <destination dir>]
[-cell <cell name>] [-noauth] [-localauth] [-help]
bos u -s <machine name> -f <files to uninstall>+
[-d <destination dir>] [-c <cell name>] [-n] [-l]
[-h]
DESCRIPTION
The bos uninstall command replaces each binary file specified by the -file argument with its ".BAK" version on the server machine named by
the -server argument, which is normally the binary distribution machine for its CPU/operating system type. It also changes the extension on
the current ".OLD" version (if any) to ".BAK". Each binary file must reside in the local /usr/lib/openafs directory unless the -dir
argument names an alternate directory.
To start using the reverted binary immediately, issue the bos restart command. Otherwise, the BOS Server automatically restarts the process
at the time defined in the /etc/openafs/BosConfig file; use the bos getrestart command to display the time and the bos setrestart time to
set it.
OPTIONS
-server <machine name>
Indicates the binary distribution machine on which to revert to the ".BAK" version of binaries. Identify the machine by IP address or
its host name (either fully-qualified or abbreviated unambiguously). For details, see bos(8).
If the machine is not a binary distribution machine and is running an "upclientbin" process, then the files are overwritten the next
time the "upclientbin" process fetches the corresponding file from the distribution machine (by default within five minutes).
-file <files to uninstall>+
Names each binary file to replace with its ".BAK" version.
-dir <destinatino dir>
Provides the complete pathname of the local disk directory containing each file named by the -file argument. It is necessary only if
the binaries are not in the /usr/lib/openafs directory.
-cell <cell name>
Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see bos(8).
-noauth
Assigns the unprivileged identity "anonymous" to the issuer. Do not combine this flag with the -localauth flag. For more details, see
bos(8).
-localauth
Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. The bos command interpreter presents the ticket
to the BOS Server during mutual authentication. Do not combine this flag with the -cell or -noauth options. For more details, see
bos(8).
-help
Prints the online help for this command. All other valid options are ignored.
EXAMPLES
The following example command overwrites the /usr/lib/openafs/kaserver file on the machine "fs4.abc.com" with its ".BAK" version, and the
current ".BAK" version by the ".OLD" version.
% bos uninstall -server fs4.abc.com -file kaserver
PRIVILEGE REQUIRED
The issuer must be listed in the /etc/openafs/server/UserList file on the machine named by the -server argument, or must be logged onto a
server machine as the local superuser "root" if the -localauth flag is included.
The bos uninstall command cannot be run against servers running in restricted mode.
