this\ncan cause the build to fail for systems that have Python 3\ninstalled as the default python:\n\n python{,-config}\n\nThe Correct Solution is to write compatibility code so that\nPython 3 works out-of-the-box.\n\nHowever, users often have an ancillary Python 2 installed:\n\n python2{,-config}\n\nTherefore, a quick fix is to allow the user to specify those\nancillary paths as the python binaries that Makefile should\nuse, thereby avoiding Python 3 altogether; as an added benefit,\nthe Python binaries may be installed in non-standard locations\nwithout the need for updating any PATH variable.\n\nThis commit adds the ability to set PYTHON and/or PYTHON_CONFIG\neither as environment variables or as make variables on the\ncommand line; the paths may be relative, and usually only PYTHON\nis necessary in order for PYTHON_CONFIG to be defined implicitly.\nSome rudimentary error checking is performed when the user\nexplicitly specifies a value for any of these variables.\n\nIn addition, this commit introduces significantly robust makefile\ninfrastructure for working with paths and communicating with the\nshell; it\u0027s currently only used for handling Python, but I hope\nit will prove useful in refactoring the makefiles.\n\nThanks to:\n\n Raghavendra D Prabhu \u003crprabhu@wnohang.net\u003e\n\nfor motivating this patch.\n\nAcked-by: Raghavendra D Prabhu \u003crprabhu@wnohang.net\u003e\nLink: http://lkml.kernel.org/r/e987828e-87ec-4973-95e7-47f10f5d9bab-mfwitten@gmail.com\nSigned-off-by: Michael Witten \u003cmfwitten@gmail.com\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" } ] }
