#9184: Allow the use of Python 3 when building GHC -------------------------------+------------------------------------------- Reporter: aspidites | Owner: Type: feature | Status: new request | Milestone: Priority: normal | Version: 7.8.2 Component: Build | Keywords: python System | Architecture: Unknown/Multiple Resolution: | Difficulty: Easy (less than 1 hour) Operating System: | Blocked By: Unknown/Multiple | Related Tickets: Type of failure: | None/Unknown | Test Case: | Blocking: | -------------------------------+------------------------------------------- Comment (by monoidal): There's one more tuple unpacking in your patch: `lambda b, d, n`. I'm afraid there are more things to change for full compatibility. It seems we run the testsuite using python2 if it is detected (see defn of `PYTHON` in `testsuite/mk/boilerplate.mk`). If I change it to `PYTHON = python3`, I get several errors with `sh validate --testsuite-only`: `execfile` is no longer available (should become something like `with open(..., 'r') as f: exec(f.read())`), `from string import join` should become string's `join` method, `reduce` is no longer builtin (needs import from functools), `import thread` should become `import _thread` for 3, `sys.stdout = os.fdopen(sys.__stdout__.fileno(), "w", 0)` fails (I stopped at that one). Would you be willing to take a look? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9184#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
