New submission from Ashley Whetter <ash...@awhetter.co.uk>:
get_externals.bat downloads and extracts libffi to a versioned directory (much like the other external libraries). See https://github.com/python/cpython/blob/v3.8.0/PCbuild/get_externals.bat#L55 However the binary release is downloaded to an unversioned directory. See https://github.com/python/cpython/blob/v3.8.0/PCbuild/get_externals.bat#L79 The visual studio project looks for the unversioned directory (https://github.com/python/cpython/blob/v3.8.0/PCbuild/python.props#L62), and so the binaries are always used. So it is possible to build from source, but you have to move libffi yourself after running `get_externals_bat --libffi-src`. I think the fix here is to make get_externals.bat and visual studio always use a versioned directory. ---------- components: Build, Windows messages: 357736 nosy: AWhetter, paul.moore, steve.dower, tim.golden, zach.ware priority: normal severity: normal status: open title: Cannot compile with libffi from source on Windows versions: Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38957> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
