Summary |
0001660: Out of date make rationale about -n and $(MAKE) |
|
Description |
Bug 0001436 added the requirement that command lines which expand the MAKE macro are still executed when -n is used, and removed some old rationale about this feature, but missed some later rationale that should also have been either removed or changed.
|
|
Desired Action |
Change:However, the System V convention of forcing command execution with -n when the command line of a target contains either of the strings "$(MAKE)" or "${MAKE}" has not been adopted. This functionality appeared in early proposals, but the danger of this approach was pointed out with the following example of a portion of a makefile:subdir:
cd subdir; rm all_the_files; $(MAKE) The loss of the System V behavior in this case is well-balanced by the safety afforded to other makefiles that were not aware of this situation. In any event, the command line <plus-sign> prefix can provide the desired functionality. to:The System V convention of forcing command execution with -n when the command line of a target expands the MAKE macro was not adopted in earlier versions of this standard, but it is now required because it has become widespread existing practice.
