Re: How do I inhibit the copying of the source files to the build tree

[Gary Oberbrunner]

I have an emacs compile-mode patch (for emacs 21.1) that makes M-x 
next-error find the real file rather than the Linked copy -- works great 
on Win32 with cons just as it is.  If anyone wants it just let me know. 
 The basics of this patch will be in the next emacs, I think; then 
you'll just need to set a simple variable to make it find the right file.

The original reason for copying/linking the source into the build tree, 
IIRC, was so that if you have a Cons-generated .h file (for instance) 
then it will be found properly by just #include "foo.h", whereas 
otherwise you'd have to generate the .h file into the *source* dir 
rather than the build dir, which would get ugly.  A small thing to be 
sure, but it has made my life easier on more than one occasion.  P

But as far as I can tell, it should be easy to just write new CCCOM etc. 
rules to do what you want, right?  Just stop using Link, and make your 
CCCOM (and all the rest) use -o%BUILDDIR%/%> or whatever you want (and 
make BUILDDIR contain your variant name).  Cons doesn't prevent this at all.
