Package Information

Wget Dependencies

Recommended

GnuTLS-3.4.4.1

Optional

libidn-1.32, OpenSSL-1.0.2d, PCRE-8.37; libwww-perl-6.13 with IO::Socket::SSL (required for the test suite); Valgrind-3.10.1 (optional for the test suite), and libpsl

Installation of Wget

Install Wget by running the following commands: 

./configure --prefix=/usr      \
            --sysconfdir=/etc  &&
make

To test the results, issue: make check. The HTTPS tests fail if openssl is used and valgrind is enabled.

Now, as the root user: 

make install

Command Explanations

--sysconfdir=/etc: This relocates the configuration file from /usr/etc to /etc.

--with-ssl=openssl: This allows the program to use OpenSSL-1.0.2d instead of GnuTLS-3.4.4.1. The combination wget-1.6.3—openssl-1.0.2a is known to be broken.

--enable-valgrind-tests: This allows the tests to be run under valgrind.

Configuring Wget

Config Files

/etc/wgetrc and ~/.wgetrc

If you have installed the Certificate Authority Certificates and you want Wget to use them, as the root user: 

echo ca-directory=/etc/ssl/certs >> /etc/wgetrc
