gentpl.py is python2/3-agnostic, but there's no way to cause it to be run with any interpreter other than 'python', it's just hard-coded into Makefile.common that way. Adjust that to use AM_PATH_PYTHON (provided by automake) to find an interpreter and run gentpl.py with that instead. This makes grub buildable when `python` does not exist (but rather `python3` or `python2` or `python2.7`, etc.) Minimum version is set to 2.6 as this is the first version with `__future__.print_function` available. Note, AM_PATH_PYTHON respects the PYTHON environment variable and will treat its value as the *only* candidate for a valid interpreter if it is set - when PYTHON is set, AM_PATH_PYTHON will not try to find any alternative interpreter, it will only check whether the interpreter set as the value of PYTHON meets the requirements and use it if so or fail if not. This means that when using grub's `autogen.sh`, as it too uses the value of the PYTHON environment variable (and if it is not set, just sets it to 'python') you cannot rely on AM_PATH_PYTHON interpreter discovery. If your desired Python interpreter is not just 'python', you must set the PYTHON environment variable, e.g. 'PYTHON=/usr/local/bin/python3 ./autogen.sh'. The specified interpreter will then be used both by autogen.sh itself and by the autotools-driven build scripts.

dnl This configure script is complicated, because GRUB needs to deal
|
||
dnl with three potentially different types:
|
||
dnl
|
||
dnl build -- the environment for building GRUB
|
||
dnl host -- the environment for running utilities
|
||
dnl target -- the environment for running GRUB
|
||
dnl
|
||
dnl In addition, GRUB needs to deal with a platform specification
|
||
dnl which specifies the system running GRUB, such as firmware.
|
||
dnl This is necessary because the target type in autoconf does not
|
||
dnl describe such a system very well.
|
||
dnl
|
||
dnl The current strategy is to use variables with no prefix (such as
|
||
dnl CC, CFLAGS, etc.) for the host type, variables with prefix "BUILD_"
|
||
dnl (such as BUILD_CC, BUILD_CFLAGS, etc.) for the build type and variables
|
||
dnl with the prefix "TARGET_" (such as TARGET_CC, TARGET_CFLAGS, etc.) are
|
||
dnl used for the target type. See INSTALL for full list of variables.
