Consider the following options instead:\r\n\r\n  - reading the Python tutorial: https://docs.python.org/3/tutorial/\r\n  - posting in the \"Users\" category on discuss.python.org: https://discuss.python.org/c/users/7\r\n  - emailing the Python-list mailing list: https://mail.python.org/mailman/listinfo/python-list\r\n  - searching our issue tracker (https://github.com/python/cpython/issues) to see if\r\n    your problem has already been reported\r\n--\u003e\r\n\r\n# Bug report\r\n\r\nWhen Python 3.12 is installed and `make install DESDIR=...` runs with Python 3.12, the entire lib-dynload directory is skipped.\r\n\r\nI believe this is a result of changes in the Makefile https://github.com/python/cpython/pull/94474\r\n\r\nTo reproduce:\r\n\r\n```\r\n$ ./configure\r\n$ make -j...\r\n$ make install DESTDIR=/tmp/python\r\n...\r\nCreating directory /usr/local/lib/python3.12/lib-dynload\r\n/usr/bin/install -c -m 755 Modules/array.cpython-312-x86_64-linux-gnu.so /usr/local/lib/python3.12/lib-dynload/array.cpython-312-x86_64-linux-gnu.so\r\n/usr/bin/install -c -m 755 Modules/_asyncio.cpython-312-x86_64-linux-gnu.so /usr/local/lib/python3.12/lib-dynload/_asyncio.cpython-312-x86_64-linux-gnu.so\r\n...\r\n```\r\n\r\nEverything is fine, `/tmp/python/usr/local/lib/python3.12/lib-dynload/` is created and contains the standard library extension modules.\r\n\r\nNow try again:\r\n\r\n```\r\n$ rm -rf /tmp/python  # undo the previous DESTDIR installation\r\n$ sudo mkdir -p /usr/local/lib/python3.12/lib-dynload  # or sudo make install without DESTDIR\r\n$ make install DESTDIR=/tmp/python\r\n...\r\n/usr/bin/install -c -m 755 Modules/array.cpython-312-x86_64-linux-gnu.so /usr/local/lib/python3.12/lib-dynload/array.cpython-312-x86_64-linux-gnu.so\r\n/usr/bin/install: cannot create regular file '/tmp/python/usr/local/lib/python3.12/lib-dynload/array.cpython-312-x86_64-linux-gnu.so': No such file or directory\r\n...\r\n/usr/bin/install -c -m 755 Modules/xxlimited.cpython-312-x86_64-linux-gnu.so /usr/local/lib/python3.12/lib-dynload/xxlimited.cpython-312-x86_64-linux-gnu.so\r\n/usr/bin/install: cannot create regular file '/tmp/python/usr/local/lib/python3.12/lib-dynload/xxlimited.cpython-312-x86_64-linux-gnu.so': No such file or directory\r\n/usr/bin/install -c -m 755 Modules/xxlimited_35.cpython-312-x86_64-linux-gnu.so /usr/local/lib/python3.12/lib-dynload/xxlimited_35.cpython-312-x86_64-linux-gnu.so\r\n/usr/bin/install: cannot create regular file '/tmp/python/usr/local/lib/python3.12/lib-dynload/xxlimited_35.cpython-312-x86_64-linux-gnu.so': No such file or directory\r\n...\r\n```\r\n\r\n`/tmp/python/usr/local/lib/python3.12/lib-dynload/` is missing entirely. The command succeeds anyway.\r\n\r\nA workaround is to `mkdir -p .../usr/local/lib/python3.12/lib-dynload/` before running `make install DESTDIR=...`\r\n\r\nIn Fedora, we build and install Python this way, when we create the package. As a result, when Python 3.12 is installed during the RPM package build, the build fails because the extension modules are missing. Since we try to use Python 3.12 as the Python for regen, this happens to us.\r\n\r\n# Your environment\r\n\r\n\u003c!-- Include as many relevant details as possible about the environment you experienced the bug in --\u003e\r\n\r\n- CPython versions tested on: 3.11.0a1 or the main branch\r\n- Operating system and architecture: Fedora Linux x86_64\r\n\r\n\u003c!--\r\nYou can freely edit this text.
