New submission from Maarten <mad...@gmail.com>:
`PCbuild/readme.txt` contains a little paragraph about how to build a static python library. The resulting static `python.lib` library contains all python C API functions. Windows DLL's don't allow missing symbols, so C extensions modules must link with a library containing the python C API symbols. When a C extension links to the static python library, it will contain a copy of all python symbols. This means that python C symbols are used twice: once by a static python.exe executable, and once for each C extension (_extension.pyw). Is there a way to use C extensions with a static Windows python.exe wuch that the python symbols are used only once? Does a statically built Windows python.exe support C extension modules at all? Thanks I'm currently working on a conan build recipe for cpython at https://github.com/conan-io/conan-center-index/pull/1510 Fow now, I'm disabling extensions on a static MSVC build. ---------- components: Windows messages: 380747 nosy: maarten, paul.moore, steve.dower, tim.golden, zach.ware priority: normal severity: normal status: open title: Limitations of building a static python library on Windows (MSVC) versions: Python 3.10, Python 3.6, Python 3.7, Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42321> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
