---------------------------------------------------------------------- (0005408) psmith (developer) - 2021-07-18 03:22 https://www.austingroupbugs.net/view.php?id=1471#c5408 ---------------------------------------------------------------------- > In 37+ years of maintaining smake, I did never receive a request to implement the := behavior from GNU make In that case we can conclude is that this difference in behavior is of little or no concern to users, since they have not requested that either version be changed to support the other. That certainly doesn't *strengthen* the argument that we need to modify the standard to provide both models. > There are four aspects with the various := implementations. I'm sorry but I didn't understand the goal of these examples. They certainly do show that the behavior of := is different among different implementations, which is no surprise (at least not to me): that's why the := operator was NOT added to the standard and ::= was added instead. If BSD make users want the BSD make behavior of :=, they have := and they can continue to use it. If they want to change it in some way, for some reason, with or without an option, again that's up to the BSD make maintainers. Why is that a discussion for the POSIX committee? This issue is proposing two NEW make operators: why should these new operators be added to the standard? The difference in behavior from the current set of available operators is obscure (as we've heard, no user has requested that either version of the behavior be changed) and there are ways to achieve the behavior these new operators provide using features available in the current POSIX standard, as shown above. I've also read through the etherpad notes from 2021-07-15 and there seems to be confusion and false information there. In particular, it is not true that GNU make is not conforming to POSIX with respect to variable expansion. If someone thinks otherwise, please provide a POSIX-conforming makefile which exhibits incorrect variable expansion behavior in GNU make.
