Wget Dependencies

Recommended

OpenSSL-1.0.2 or GnuTLS-3.3.12

Optional

libidn-1.29, PCRE-8.36; libwww-perl-6.13 with IO::Socket::SSL (required for the test suite); Valgrind-3.10.1 (optional for the test suite, but failures are introduced), Dante, and libpsl

Installation of Wget

Install Wget by running the following commands: 

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

To test the results, issue: make check.

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 work with OpenSSL-1.0.2. It can be omitted if GnuTLS-3.3.12 is found or the HTTPS protocol is not needed.

--enable-valgrind-tests: This allows the tests to be optionally run under valgrind. Unfortunately, failures are introduced.

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
