### Wget Dependencies

#### Recommended

libpsl-0.23.3

#### Recommended at runtime

make-ca-1.16.1

#### Optional

GnuTLS-3.8.13, HTTP-Daemon-6.17 (for the test suite), IO-Socket-SSL-2.099 (for the test suite), libidn2-2.3.8, libproxy-0.5.12, and Valgrind-3.27.1 (for the test suite)

## Installation of Wget

First, make a fix to make the package compatible with OpenSSL 4. The bash variable is for presentation purposes due to the long line.

    NEW_LINE='#if !defined OPENSSL_NO_SSL3_METHOD '
    NEW_LINE+='&& OPENSSL_VERSION_NUMBER < 0x40000000L'

    sed -i "/SSL3/c $NEW_LINE" src/openssl.c

    unset NEW_LINE

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 use openssl instead of GnuTLS-3.8.13.

`--enable-libproxy`: This switch allows wget to use libproxy for proxy configuration. Use it if you have the libproxy-0.5.12 package installed and wish to use a proxy server.

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