Python-2.7.6
Installation of Python 2
Install Python 2 by running the
following commands:
./configure --prefix=/usr \
--enable-shared \
--with-system-expat \
--with-system-ffi \
--enable-unicode=ucs4 &&
make
To test the results, issue: make
test.
Now, as the root
user:
make install &&
chmod -v 755 /usr/lib/libpython2.7.so.1.0
Since Python 2 is in maintenance
mode, and Python 3 is recommended
by upstream for development, probably, you do not need to install
the documentation. However, if you still want to install
documentation for both Python
versions, be sure to define PYTHONDOCS variable for the version you
want to use, each time you need to consult the documentation. If
you have downloaded the preformatted documentation from http://docs.python.org/download.html,
install it as the root
user:
install -v -dm755 /usr/share/doc/python-2.7.6 &&
tar --strip-components=1 -C /usr/share/doc/python-2.7.6 \
--no-same-owner -xvf ../python-2.7.6-docs-html.tar.bz2 &&
find /usr/share/doc/python-2.7.6 -type d -exec chmod 0755 {} \; &&
find /usr/share/doc/python-2.7.6 -type f -exec chmod 0644 {} \;
