Category: Distutils Group: None Status: Open Resolution: None Priority: 5 Submitted By: Albert Strasheim (albertstrasheim) Assigned to: Nobody/Anonymous (nobody) Summary: Long command lines don't work on Windows Initial Comment: Windows has a 32k command line limit, described here: http://blogs.msdn.com/oldnewthing/archive/2003/12/10/56028.aspx The SciPy project is running into problems when using distutils to compile LAPACK from source, because the large number of source files results in a command line of more than 70,000 characters. Windows has a way of dealing with this problem, namely putting the command line arguments in a file and passing that file to executable with prepended with an @, i.e. you want to run something like lib.exe @tempdir\tempargs.lnk SCons takes care of this through it's TEMPFILE mechanism which uses the TempFileMunge class which can be perused here: http://scons.tigris.org/source/browse/scons/trunk/src/engine/SCons/Platform/__init__.py?rev=1582&view=markup I think this problem can easily be addressed in distutils by modifying the _spawn_nt method in spawn.py to switch to this temp file method when the command line length exceeds some threshold. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1539295&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
