Fair enough, but what I really want is something that doesn't require my makefiles to have to discriminate between what kind of python exe is first in the path; I want them to be equipotent, and I don't want to have to install things that aren't standard; I want a makefile that can be invoked from either cmd.exe or bash, that can run on a system that has either cygwin python or win32 python or both installed, that isn't sensitive to which one comes in which order in $PATH, and that doesn't require anything extra to be installed. But I guess I could always use a makefile rule to create python.bat in the objdir I'm building in.... hmm. That might have been a bit simpler than my current solution, which uses a fairly gross makefile hack to search $PATH and some default install locations for any instances of python.exe, then discards any which live in a ".../bin/.." subdir to try and eliminate the cygwin version! > c) the code in spawn.cc currently treats any file with a .exe > extension > specially, and passes it on to CreateProcess without looking > into it any > more than that.

LOL, I don't really think it's within my abilities to come up with a patch for spawn.cc that modifies the behaviour of cmd.exe....... cheers, DaveK -- Can't think of a witty .sigline today.... -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
