Subject RE: Window's Makefiles
Date Fri, 23 Jan 1998 19:09:30 GMT
I'm comfortable with the Visual C++ IDE, and with having
it generate makefiles for me.  Last night, I spent about
10 minutes adding a new profiling target to the makefiles
for NT using the IDE.  If I had to do it by hand, it never
would have gotten done.

Loosing this convenience and familarity for Windows
developers will make it (IMHO) hard to convince people
to sign on to work on the NT version.  I think most VC
developers (myself included) would rather not deal with
makefile maintenance if we can help it.

Another point - if you keep the DSP files around, and they fall
out of sync with the makefiles, you can have two completely
different builds of the same source code (an IDE build using
the DSP and a makfeil build from the command line).  Not a good
thing.  On top of that, exporting the DSP makefile will overwrite
the hand-edited makefile.

Keep the DSP files around.  I'll volunteer to maintain them,
if it's that much of an issue.
