New submission from Andre Heider <[EMAIL PROTECTED]>: The MSVC build process currently embeds the .manifest file, which is generated by the MS linker, in the following files:
- python.exe - pythonXY.dll - *.pyd The latter is problematic on machines without the MS CRT redistributable installed (No CRT files in %WINDIR%\WinSxS). While this error won't occur when the python package is installed, it will in other cases like in ours: We use the python interpreter within our application and do ship python25.dll. We also ship the MS CRT files and place them next to the main application (MS calls this "private assemblies" and "xcopy deployment). We do not install the redistributable, because it needs admin rights. If a user tries to "import socket" on this setup it will fail, because the Side by Side / Fusion loader expects the CRT next to the calling Binary (%PYTHONHOME%\DLLs\_socket.pyd) because of the manifest. The solution is to not embed the manifest in the *.pyd Modules. This way the modules just link against msvc*.dll. This works because the windows loader has already mapped the CRT into memory for the process (either through python.exe or pythonXY.dll). This is also the only reliable way i could find to fix the import on machines without redist. Attached you'll find a patch for the MSVC90 build, apply with -p5. It will only patch the release file, PCbuild8/pyd_d.vsprops requires the same fix. Trolltech also uses this approach for its plugins: https://trolltech.com/developer/faqs/faq.2007-10-19.6185511205 ---------- components: Build files: Python-2.5.2-no.manifest.in.pyd.diff keywords: patch messages: 74723 nosy: aheider severity: normal status: open title: Do not embed manifest files in *.pyd when compiling with MSVC versions: Python 2.5 Added file: http://bugs.python.org/file11783/Python-2.5.2-no.manifest.in.pyd.diff _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue4120> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
