(For strict compliance with POSIX.2, changing MAKEOVERRIDES does not affect MAKEFLAGS if the special target `.POSIX' If either condition is not met a bug should be opened so the logic can be modified to prevent any future failure conditions from silently sneaking into the tree.

This one and the accepted answer are wrong. –Kristof Provost Mar 27 '12 at 6:22 1 @KristofProvost - Ah. For example, suppose you have a subdirectory `subdir' which has its own makefile, and you would like the containing directory's makefile to run make on the subdirectory. The - is discarded before the command is passed to the shell for execution. Makefile Error Handling See section Variables from the Environment.

One trivial way to validate logic blocks like these is leverage the tryserver and modify the makefile to perform a negative test. Make Error 1 Ignored If your makefiles depend on this behavior and you want to be compatible with old versions of make, you can write a rule for the special target .EXPORT_ALL_VARIABLES instead of using in a new shell. For example, clean: -rm -f *.o This causes rm to continue even if it is unable to remove a file.

Makefile Exit On Error

Likewise, you can use unexport by itself to tell make not to export variables by default.

If a target has already been made, it will of course skip that target and the useless file may not be there. Make is very good at control flow and processing but not so much as a scripting language. Recipe For Target Failed Makefile

A rule in the makefile for the special target .SILENT without dependencies has the same effect (see section Special Built-in Target Names). .SILENT is essentially obsolete since `@' is more flexible. Except by explicit request, make exports a variable only if it is either defined in the environment initially or set on the command line, and if its name consists only of It would be very bad for personal choices like this to affect the functioning of makefiles. http://computerhelpdev.com/exit-code/return-code-128-git.php For example, after an error in compiling one object file, ‘make -k’ will continue compiling other object files even though it already knows that linking them will be impossible.
