# There are multiple Python 3 versions packaged, but only one can be the "main" version # That means that it owns the "python3" namespace: # - python3 package name # - /usr/bin/python3 command # - python3-foo packages are meant for this version # Other versions of Python 3 always contain the version in the namespace: # - python3.XX package name # - /usr/bin/python3.XX command # - python3.XX-foo packages (if allowed) # # Python spec files use the version defined here to determine defaults for the # %%py_provides and %%python_provide macros, as well as for the "pythonname" generator that # provides python3-foo for python3.XX-foo and vice versa for the default "main" version. # E.g. in Fedora 33, python3.9-foo will provide python3-foo, # python3-foo will provide python3.9-foo. # # There are two macros: # # This always contains the major.minor version (with dots), default for %%python3_version. %__default_python3_version 3.9 # # The pkgname version that determines the alternative provide name (e.g. python3.9-foo), # set to the same as above, but historically hasn't included the dot. # This is left intentionally a separate macro, in case the naming convention ever changes. %__default_python3_pkgversion %__default_python3_version # python3_pkgversion specifies the version of Python 3 in the distro. # For Fedora, this is usually just "3". # It can be a specific version distro-wide (e.g. "36" in EPEL7). # Alternatively, it can be overridden in spec (e.g. to "3.8") when building for alternate Python stacks. %python3_pkgversion 3 # Define the Python interpreter paths in the SRPM macros so that # - they can be used in Build/Requires # - they can be used in non-Python packages where requiring pythonX-devel would # be an overkill # use the underscored macros to redefine the behavior of %%python3_version etc. %__python2 /usr/bin/python2 %__python3 /usr/bin/python%{python3_pkgversion} # use the non-underscored macros to refer to Python in spec, etc. %python2 %__python2 %python3 %__python3 # See https://fedoraproject.org/wiki/Changes/PythonMacroError %__python %{error:attempt to use unversioned python, define %%__python to %{__python2} or %{__python3} explicitly} # Users can use %%python only if they redefined %%__python (e.g. to %%__python3) %python %__python # Define where Python wheels will be stored and the prefix of -wheel packages # - In Fedora we want wheel subpackages named e.g. `python-pip-wheel` that # install packages into `/usr/share/python-wheels`.
