Install wget on OS X Lion

2011/11/05

A pre-requisite for this to work is that you have the second disc of utilities that came with your Mac installed. This disc will provide a bunch of utilities required to compile code. Alternatively, you can Install Xcode from the App Store (it’s free!) and you will get all of the same utilities.

UPDATE: Installing Xcode is no longer good enough.You will now need to open Xcode, go to preferences (Cmd + ,), go to Downloads, and install the Command Line Tools feature. This installs a bunch of development tools onto your system.

Run the following commands in a terminal window to compile wget on OS X Lion:

curl -O http://ftp.gnu.org/gnu/wget/wget-1.13.4.tar.gz

tar -xzvf wget-1.13.4.tar.gz

cd wget-1.13.4

./configure --with-ssl=openssl

make

sudo make install

which wget #Should output: /usr/local/bin/wget

Note the with-ssl=openssl option in the command above. If you omit that, you will get the following error:

...

checking for compress in -lz... yes

checking for gpg_err_init in -lgpg-error... no

checking for gcry_control in -lgcrypt... no

checking for libgnutls... no

configure: error: --with-ssl was given, but GNUTLS is not available.

username@host:~/wget-1.13.4 $

The reason for this is that GNUTLS isn’t included with Mac OS X, but the equally usable library OpenSSL is available.
