VPATH question - Gnu make vs. Lucent nmake

[Meinecke, Jon]

I'm trying to setup a veiwpath source/build tree environment

with Gnu make similar to that supported by Lucent nmake.

 

The model is a common source tree, a common build tree,

and a developer source/build tree.  The goal is to use built

targets in the common tree unless there is a source file

in the developer tree.  These "local" source files should

always take precedence over common source files, even

if older.

 

gmake's VPATH and vpath work fine for locating sources and

targets, but I don't see an obvious way to force a local build

target when the local source file is older than the common 

built object.

 

Is this possible with gmake?

 

I've checked the list archives and couldn't find an obvious answer.

If this has already been discussed, please refer me to the

relevant threads.

 

Thanks,
