			Installation Procedure

0) Preparation

To build and install GNU Wget, you need to unpack the archive (which
you have presumably done, since you are reading this), and read on.
Like most GNU utilities, Wget uses the GNU Autoconf mechanism for
build and installation; those of you familiar with compiling GNU
software will feel at home.

1) Configuration

To configure Wget, run the configure script provided with the
distribution.  It will create the Makefiles needed to start the
compilation.  You may use the standard arguments Autoconf-created
configure scripts take, the most important ones being:

  --help                  display a help message and exit

  --prefix=PREFIX         install architecture-independent files in PREFIX
                          (/usr/local by default)
  --bindir=DIR            user executables in DIR (PREFIX/bin)
  --infodir=DIR           info documentation in DIR [PREFIX/info]
  --mandir=DIR            man documentation in DIR [PREFIX/man]

  --build=BUILD           configure for building on BUILD [BUILD=HOST]
  --host=HOST             configure for HOST [guessed]
  --target=TARGET         configure for TARGET [TARGET=HOST]

--enable and --with options recognized (mostly Wget-specific):
  --with-ssl[=SSL_ROOT]   link with libssl [in SSL_ROOT/lib] for https: support
  --disable-opie          disable support for opie or s/key FTP login
  --disable-digest        disable support for HTTP digest authorization
  --disable-ntlm          disable support for HTTP NTLM authorization
  --disable-debug         disable support for debugging output
  --disable-nls           do not use Native Language Support
  --disable-largefile     omit support for large files
  --disable-ipv6          disable IPv6 support

If you want to configure Wget for installation in your home directory,
you can type:

    ./configure --prefix=$HOME

You can customize many settings simply by editing the Makefiles and
`src/config.h'.  The defaults should work without intervention, but it
is useful to have a look at things you can change there.

configure will try to find a compiler in your PATH, defaulting to
`gcc', but falling back to `cc' if the former is unavailable.  This is
a reasonable default on most Unix-like systems, but sometimes you
might want to override it.  The compiler choice is overridden with the
value of the `CC' environment variable.  For example, to force
compilation with the Unix `cc' compiler, invoke configure like this:

    ./configure CC=cc

This assumes that `cc' is in your path -- if it is not, simply replace
"cc" with "/path/to/cc".  Note that environment variables that affect
configure can be set with the usual shell syntax `var=value
./configure' (assuming an sh-compatible shell).  In addition to that,
configure allows environment variables to be specified as arguments in
the form "var=value", which are shell-independent.

Environment variables that affect `configure' include: CFLAGS for
compilation flags, LDFLAGS for linker flags, and CPPFLAGS for
preprocessor flags.

If you have OpenSSL libraries installed at one of the default
locations, such as the system library directories or /usr/local/lib or
/usr/local/ssl/lib, configure will autodetect them.  If they are
installed elsewhere, you need to specify the OpenSSL root directory.
For instance, if libcrypto.* and libssl.* are in /opt/openssl/lib, you
need to `configure --with-ssl=/opt/openssl'.

To configure Wget on Windows, read the instructions in
`windows/README'.  If this doesn't work for any reason, talk to the
Windows developers listed there; I do not maintain the port.  Those
instructions do not apply to the "Cygwin" environment, where Wget
should build out of the box as described here.

2) Compilation

To compile GNU Wget after it has been configured, simply type make.
If you do not have an ISO C (C89) compiler, Wget will try to K&R-ize
its sources on the fly.  This should make GNU Wget compilable on
almost any Unix-like system you are likely to encounter.

After the compilation a ready-to-use `wget' executable should reside
in the src directory.  At this point there is no formal test suite for
testing the binary, but it should be easy enough to test whether the
basic functionality works.

3) Installation

Use `make install' to install GNU Wget to directories specified to
configure.  To install it in a system directory (which is the
default), you will need to be root.  The standard prefix is
"/usr/local/", which can be changed using the `--prefix' configure
option.

The installation process will copy the wget binary to $PREFIX/bin,
install the wget.info* info pages to $PREFIX/info, the generated
manual page (where available) wget.1 to $PREFIX/man/man1, and the
default config file to $PREFIX/etc, unless a config file already
exists there.  You can customize these directories either through the
configuration process or making the necessary changes in the Makefile.

To delete the files created by Wget installation, you can use `make
uninstall'.
