6.51.1. Installation of Python 3
Prepare Python for compilation:
./configure --prefix=/usr \
--enable-shared \
--with-system-expat \
--with-system-ffi \
--with-ensurepip=yes
./configure --prefix=/usr \
--enable-shared \
--with-system-expat \
--with-system-ffi \
--with-ensurepip=yes
The meaning of the configure options:
--with-system-expat
This switch enables linking against system version of Expat.
--with-system-ffi
This switch enables linking against system version of libffi.
--with-ensurepip=yes
This switch enables building pip and setuptools packaging programs.
Compile the package:
make
make
The test suite requires TK and and X Windows session and cannot be run until Python 3 is reinstalled in BLFS. Install the package:
make install
chmod -v 755 /usr/lib/libpython3.7m.so chmod -v 755 /usr/lib/libpython3.so
ln -sfv pip3.7 /usr/bin/pip3
make install
chmod -v 755 /usr/lib/libpython3.7m.so chmod -v 755 /usr/lib/libpython3.so
ln -sfv pip3.7 /usr/bin/pip3
The meaning of the install commands:
chmod -v 755 /usr/lib/libpython3.{7m.,}so
Fix permissions for libraries to be consistent with other libraries.
If desired, install the preformatted documentation:
install -v -dm755 /usr/share/doc/python-3.7.4/html
tar --strip-components=1 \
--no-same-owner \
--no-same-permissions \
-C /usr/share/doc/python-3.7.4/html \
-xvf ../python-3.7.4-docs-html.tar.bz2
install -v -dm755 /usr/share/doc/python-3.7.4/html
tar --strip-components=1 \
--no-same-owner \
--no-same-permissions \
-C /usr/share/doc/python-3.7.4/html \
-xvf ../python-3.7.4-docs-html.tar.bz2
The meaning of the documentation install commands:
--no-same-owner and --no-same-permissions
Ensure the installed files have the correct ownership and permissions. Without these options, using tar will install the package files with the upstream creator's values.
