This post explains how to compile Python v3.2 including support for the GNU Readline Library on MacOS X 10.7 (Lion), not using tools like MacPorts. One of the problems we try to solve is making history work in the interactive Python interpreter.
First, you need a fresh copy of the GNU Readline Library and compile it. At the time of writing, readline v6.2 was the latest. Fire up a Terminal and do the following:
$ tar xzf readline-6.2.tar.gz $ cd readline-6.2 $ MACOSX_DEPLOYMENT_TARGET=10.7 ARCHFLAGS="-arch x86_64" ./configure --prefix=/opt/local $ make && sudo make install
Note that you can change the location
/opt/local to anything you like, but avoid
/usr/lib or other system location.
When readline compiled and installed successfully, compile Python v3.2 as follows:
$ tar xzf Python-3.2.3.tgz $ cd Python-3.2.3 $ LDFLAGS="-L/opt/local/lib" CFLAGS="-I/opt/local/include" \ ./configure --prefix=/opt/python/3.2.3 $ make && sudo make install
Note that you might have more arguments to pass to the
./configure if you have special needs. Note also that
/opt/python/3.2.3 is where Python will be installed to avoid clashing with the system provided Python installations.
You should now have history support in the Python interpreter:
$ /opt/python/3.2.3/bin/python3 >>> import this >>>
