Python 2.7 will not be maintained past 2020. Many scripts on the tree are used during the build and should keep Python 2 compatibility for a while. This is not the case for the runtime test infra. It's meant to be run in modern distros only, so it can safely switch to support Python 3 only. An advantage of this approach is to have less scenarios to test in. Otherwise every change to the test infra or runtime tests would need to be tested against both versions of the interpreter, increasing the effort of the developers, to ensure the compatibility to Python 2 was not broken. In order to accomplish the change to Python 3: - change the shebang for run-tests; - use Python 3 urllib as a drop-in replacement for Python 2 urllib2; - when writing the downloaded binary files, explicitly open the output file as binary; - when subprocess is used to retrieve the text output from commands, explicitly ask for text output. For this, use 'universal_newlines' because 'text' was added only on Python 3.7; - when pexpect is used to retrieve the text output from qemu or git, explicitly ask for text output using 'encoding'; - the code using csv currently follows the example in the documentation for the Python 2 module, change it to follow the example in the documentation for the Python 3 module; - fix the relative import for test_git.py to be Python 3 compliant.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
