New submission from Christoph Gohlke <cgoh...@uci.edu>: Wininst-9.0.exe and wininst-9.0-amd64.exe are missing MSVCRT90 dependencies in the embedded manifest.
While testing installers of pywin32 <http://sourceforge.net/projects/pywin32/> version 214 built with Python 2.6.4 and the msvc9compiler_stripruntimes_regexp2.diff patch from Issue4120 <http://bugs.python.org/issue4120>, I noticed that the post_install script fails with an ImportError while trying to load extensions without embedded MSVCRT90 manifest: Traceback (most recent call last): File "<string>", line 601, in <module> File "<string>", line 311, in install File "<string>", line 149, in LoadSystemModule ImportError: DLL load failed: The specified module could not be found. The code that fails is: mod = imp.load_module(modname, None, filename, ('.dll', 'rb', imp.C_EXTENSION)) where modname='pywintypes' and filename points to an existing 'pywintypes26.dll' file. The post_install script runs fine when executed from the main python.exe interpreter. A possible fix is to embed a MSVCRT90 dependency into wininst-9.0.exe and wininst-9.0-amd64.exe using the following linker switches: /MANIFESTDEPENDENCY:"type='Win32' name='Microsoft.VC90.CRT' version='9.0.21022.8' processorArchitecture='X86' publicKeyToken='1fc8b3b9a1e18e3b'" /MANIFESTDEPENDENCY:"type='Win32' name='Microsoft.VC90.CRT' version='9.0.21022.8' processorArchitecture='amd64' publicKeyToken='1fc8b3b9a1e18e3b'" See also <http://msdn.microsoft.com/en-us/library/ew0y5khy.aspx> A patch against the Python 2.6 PCbuild\bdist_wininst.vcproj is attached. I tested it with Python 2.6.4, 32 and 64 bit, and pywin32 214 installers built with the following command: python.exe setup.py bdist_wininst --user-access-control=auto --install-script=wxpython_win_post_install.py ---------- assignee: tarek components: Distutils, Windows files: bdist_wininst.vcproj.patch keywords: patch messages: 98694 nosy: cgohlke, tarek severity: normal status: open title: Bdist_wininst installers fail to load extensions built with Issue4120 patch versions: Python 2.6 Added file: http://bugs.python.org/file16086/bdist_wininst.vcproj.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue7833> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
