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

There is a need to link a new dynamic library to a big number of exes.

laptop_mode
LAPTOP_MODE(8) System Manager's Manual LAPTOP_MODE(8)
NAME
/usr/sbin/laptop_mode - apply laptop mode settings
SYNOPSIS
/usr/sbin/laptop_mode [ cmd ] [ force ]
DESCRIPTION
This manual page documents briefly the /usr/sbin/laptop_mode command. laptop_mode is a program that applies the settings given in the
/etc/laptop-mode/laptop-mode.conf configuration file. The primary use is to control the laptop mode feature included in Linux kernels with
versions 2.6.6 and higher, and 2.4.23 and higher. This feature increases battery life by letting your hard drive spin down. This is
achieved by grouping disk write activity into "chunks" that are spaced at larger intervals than they normally would be. In addition to sup-
porting the Linux kernel's laptop mode feature, /usr/sbin/laptop_mode also supports various power saving modules which are configured
through configuration files in the /etc/laptop-mode/conf.d directory.
It is not recommended to call /usr/sbin/laptop_mode directly to start or stop laptop mode, except in hardware event handlers. To apply new
configuration settings from laptop-mode.conf, call the laptop-mode service init script with the reload parameter.
COMMANDS
Specify force as the second parameter to force laptop_mode to re-apply a state even if the computer is already in that state. These are the
values that are allowed for cmd :
auto Enable or disable laptop mode based on the current power state. Note that this will not do anything if the laptop-mode service
has not been started!
status Display a status report about everything that laptop_mode affects.

laptop-mode.conf(8).
