Compiling From Repository Sources

   To reduce bandwidth and needless updates, the source code repository
   does not contain automatically-generated files, even when these are
   normally present in the distribution tarballs. Therefore, to build GNU
   Wget from the sources in the repository, you'll need to have one or
   more of the following (note that gettext, OpenSSL, GnuTLS, libidn,
   libiconv, libpsl, libpcre and pkg-config are not absolutely required):

     * [20]autoconf (currently, GNU Wget requires version 2.61). This is
       needed to generate the configure script from configure.in. This is
       not required when building from a tarball distribution; only when
       building from repository sources.

     * [21]automake (currently, GNU Wget requires version 1.10.1). This is
       needed for generating the Makefile.in templates that the configure
       script uses to generate the Makefiles. As with autoconf, it is not
       required when building from a tarball distribution; only when
       building from repository sources.

     * [22]flex is needed to generate the CSS-parsing code.

     * [23]Perl, if you wish to generate the wget(1) manpage, or run the
       tests in the tests/ sub directory. Tarball distributions include an
       already-generated wget.1 manual. The command "make check" runs the
       test suite written in perl. To execute all the tests you need
       [24]libwww-perl perl library. If "perl -MCPAN -e 'install
       Bundle::LWP'" fails then you most likely don't have cpan module
       installed. First download [25]CPAN and [26]install it. Then execute
       "perl -MCPAN -e 'install Bundle::LWP'". Now "make check" should
       pass most of the tests in the test suite.

     * [27]texinfo in order to generate Info, PostScript and/or HTML
       documentation. You don't need texinfo in order to generate the
       wget(1) manpage; however, note that the manpage does not include
       the full documentation. Tarball distributions include the
       already-generated documentation in these formats.

     * [28]gettext, if you wish to compile with NLS (Native Language
       Support), which is enabled by default. If you do not have gettext,
       you can compile without it by specifying --disable-nls to the
       ./configure script. This is true regardless of where you obtained
       the source you're building. NOTE: if you get errors about
       AM_GNU_GETTEXT and/or AM_INTL_SUBDIR, you probably have a buggy
       version of GNU m4. Upgrade to the latest version. You may also need
       to export M4=<new m4 path>, to be sure that autoconf/automake use
       it instead of the old one.

     * [29]GnuTLS to allow encrypted data transfer (HTTPS).
       You need the header files and the library installed.
       As an alternative, you can use [30]OpenSSL by specifying
       --with-ssl=openssl to the ./configure script.
       If you do not want HTTPS support, specify --without-ssl to the
       ./configure script.
       If you want to compile+link a non-system library version use
       --with-libgnutls-prefix (or if having pkg-config: see description
       below).

     * [30]OpenSSL  to allow encrypted data transfer (HTTPS) an an
       alternative to [31]GnuTLS.
       You need the header files and the library installed.
       If you want to compile+link a non-system library version use
       --with-libssl-prefix (or if having pkg-config: see description below).

     * [31]libidn is required for IDN/IRI support (non-ASCII characters
       within what would otherwise be URLs).

     * [32]libiconv is required on non-GNU systems, for IDN/IRI support.
       On GNU systems, the functionality provided by libiconv is already
       present in the system libraries.

     * [33]git is used to fetch gnulib files trough the bootstrap.sh script.

     * [34]libpsl is required for using a public suffix list to check for valid
       cookie domains. You need the header files and the library installed.

     * [35]libpcre is required for using Perl-compatible regular expressions
       with --accept-regex and --reject-regex. You need the header files and
       the library installed to compile and link Wget with PCRE support.

     * [36]pkg-config helps the ./configure script to find installed libraries.
       Most libraries provide a pkg-config file (.pc extension) with
       information about dependencies, header file and library locations.
       Distributions deliver their specific .pc file to each library.
       If you want to compile+link against your own library version, make a
       copy of the appropriate .pc file and amend it to your needs (e.g. edit
       the line starting with prefix=). Before you execute the ./configure
       script, set (and export) PKG_CONFIG_PATH to the directory where you
       saved the .pc file. Example:
       $ PKG_CONFIG_PATH="." ./configure


   For those who might be confused as to what to do once they check out
   the source code, considering configure and Makefile do not yet exist at
   that point, a shell script called bootstrap has been provided. After
   calling ./bootstrap you're ready to build GNU Wget in the normal
   fashion, with ./configure and make.

   So, to sum up, after checking out the source code as described above,
   you may proceed as follows:
    1. Change to the topmost GNU Wget directory:
 $  cd wget        # assumes you've cloned a repository to "./wget"
    2. Generate all the automatically-generated files required prior to
       configuring the package:
 $  ./bootstrap
    3. Configure the package and compile it:
 $  ./configure --enable-assert [some_parameters]
 $  make
    4. Hack, compile, test, hack, compile, test...
 $  src/wget --version
 GNU Wget 1.12-devel (9cb2563197bc)

 All developers are requested to enable the assertions on their development
 builds to ensure a stable codebase. Assertions are added to state certain
 assumptions about the code and its data which all developers should be mindful
 of. To enable assertions, run the configure command with the --enable-assert
 option, like this:

 $ ./configure --enable-assert [other configure options]
