Relocatable Installation
========================
Enabling Relocatability
=======================
By default, `make install' will install a package with hardwired
file names, and the package will not work correctly when copied or
moved to a different location in the filesystem.
It has been a pain for many users of GNU packages for a long time
that packages are not relocatable. It means a user cannot copy a
program, installed by another user on the same machine, to his home
directory, and have it work correctly (including i18n). So many users
need to go through `configure; make; make install' with all its
dependencies, options, and hurdles.
Some packages pay attention to the `--enable-relocatable' option to
`configure'. This option makes the entire installed package
relocatable. This means, it can be moved or copied to a different
location on the filesystem. It is possible to make symlinks to the
installed and moved programs, and invoke them through the symlink. It
is possible to do the same thing with a hard link _only_ if the hard
linked file is in the same directory as the real program.
Red Hat, Debian, and similar package systems solve the "ease of
installation" problem, but they hardwire path names, usually to `/usr'
or `/usr/local'. This means that users need root privileges to install
a binary package, and prevents installing two different versions of the
same binary package.
For reliability it is best to give together with --enable-relocatable
a `--prefix' option pointing to an otherwise unused (and never used
again) directory, for example, `--prefix=/tmp/inst$$'. This is
recommended because on some OSes the executables remember the location
of shared libraries (and prefer them over LD_LIBRARY_PATH !), therefore
such an executable will look for its shared libraries first in the
original installation directory and only then in the current
installation directory.
A relocatable program can be moved or copied to a different location

LD_LIBRARY_PATH variable when it is launched.)
To configure a program to be relocatable, add `--enable-relocatable'
to the `configure' command line.
The runtime penalty and size penalty are nearly zero on Linux 2.2 or
newer (just one system call more when an executable is launched), and
small on other systems (the wrapper program just sets an environment
variable and execs the real program).
On some OSes the executables remember the location of shared
libraries and prefer them over any other search path. Therefore, such
an executable will look for its shared libraries first in the original
installation directory and only then in the current installation
directory. Thus, for reliability, it is best to also give a `--prefix'
option pointing to a directory that does not exist now and which never
will be created, e.g. `--prefix=/nonexistent'. You may use
`DESTDIR=DEST-DIR' on the `make' command line to avoid installing into
that directory.
We do not recommend using a prefix writable by unprivileged users
(e.g. `/tmp/inst$$') because such a directory can be recreated by an
unprivileged user after the original directory has been removed. We
also do not recommend prefixes that might be behind an automounter
(e.g. `$HOME/inst$$') because of the performance impact of directory
searching.
Here's a sample installation run that takes into account all these
recommendations:
./configure --enable-relocatable --prefix=/nonexistent
make
make install DESTDIR=/tmp/inst$$
Installation with `--enable-relocatable' will not work for setuid or
setgid executables, because such executables search only system library
paths for security reasons. Also, installation with
`--enable-relocatable' might not work on OpenBSD, when the package
contains shared libraries and libtool versions 1.5.xx are used.
