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. 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'.
