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\nA build of Python 3.11b5's fails to find lib-dynload path if the following normally ok combination of criteria are met:\r\n- The framework is made or modified in such a away to be relocatable (dynamic links are relative using @loader_path, etc) instead of absolute path\r\n- The framework is installed in a location it wasn't built at\r\n- python is executed by a symlink from elsewhere\r\n\r\n# Your environment\r\n\r\nTo reproduce this easily, I decompressed the installable package into my home directory, making a framework structure that would normally run. I do have to modify the linking to work relocated, using the following commands:\r\n```\r\n install_name_tool -change /Library/Frameworks/Python.framework/Versions/3.11/Python @loader_path/../Python Python.framework/Versions/3.11/bin/python3.11\r\n install_name_tool -change /Library/Frameworks/Python.framework/Versions/3.11/Python @loader_path/../../../../Python Python.framework/Versions/3.11/Resources/Python.app/Contents/MacOS/Python\r\n\r\n```\r\nI then symlink the python executable.\r\n\r\n`ln -s Python.framework/Versions/3.11/bin/python3.11 python3.11\r\n`\r\n\r\nthe following command works fine\r\n\r\n` ./Python.framework/Versions/3.11/bin/python3.11 -c \"import math\"\r\n`\r\n\r\nwhile this does not\r\n```\r\n ./python3.11 -c \"import math\"\r\nCould not find platform dependent libraries \u003cexec_prefix\u003e\r\nTraceback (most recent call last):\r\n  File \"\u003cstring\u003e\", line 1, in \u003cmodule\u003e\r\nModuleNotFoundError: No module named 'math'\r\n\r\n```\r\neven though the shell itself works normally, just the lib-dynload is not being found.\r\n\r\nI can make it work with the attached patch, but I don't assume it is the correct way to fix it\r\n[relocated_framework.patch.gz](https://github.com/python/cpython/files/9213546/relocated_framework.patch.gz)\r\n.","author":{"url":"https://github.com/jpgarcia-ssec","@type":"Person","name":"jpgarcia-ssec"},"datePublished":"2022-07-28T19:25:46.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/95400/cpython/issues/95400"}
