how to stop and exit when errors occur in for loop make up vote 2 down vote favorite I use 'for' loop to make subdirectories,but when some errors occur when make in subdirectory,it continues to make the next directory,can i stop when errors occur 'make' in subdirectory? all : for i in $(SUBDIRS); do make -C $$i dll; done; || make[1]: *** [bd_snmp.o] error 1 make exit on error make[1]: Leaving directory `/home/ping/work/svnsocserv/src/bd_snmp' make[1]: Entering directory `/home/ping/work/svnsocserv/src/bd_snmp_proxy' makefile share|improve this question asked Sep 22 '13 at 6:19 PigeonLueng 334 add a comment| 1 Answer 1 active oldest votes up vote 4 down vote accepted Sure, just add something to your shell script that checks: all: for i in $(SUBDIRS); do $(MAKE) -C $$i dll || exit 1; done (note ALWAYS use $(MAKE) to recursively invoke sub-makes, never make). This is not a great method though, because while it does exit immediately when a sub-make fails it doesn't obey the make -k option to keep going. share|improve this answer answered Sep 22 '13 at 6:31 MadScientist 27k32240 thanks,it works properly.

in the recipe is executed in a new shell; after the last line is finished, the rule is finished. If there is an error (the exit status is nonzero), make gives up on the current rule, and perhaps on all rules. Sometimes

Makefile Ignore Error And Continue

the failure of a certain recipe line does not indicate a problem. For example, you may

Makefile Exit Status

use the mkdir command to ensure that a directory exists. If the directory already exists, mkdir will report an error, but you probably recipe for target failed makefile want make to continue regardless. To ignore errors in a recipe line, write a ‘-’ at the beginning of the line’s text (after the initial tab). The ‘-’ is discarded before the line is passed to the shell for http://stackoverflow.com/questions/18940980/gnu-make-how-to-stop-and-exit-when-errors-occur-in-for-loop-make execution. For example, clean: -rm -f *.o This causes make to continue even if rm is unable to remove a file. When you run make with the ‘-i’ or ‘--ignore-errors’ flag, errors are ignored in all recipes of all rules. A rule in the makefile for the special target .IGNORE has the same effect, if there are no prerequisites. These ways of ignoring errors are obsolete because ‘-’ is more flexible. When errors are to be ignored, https://www.gnu.org/s/make/manual/html_node/Errors.html because of either a ‘-’ or the ‘-i’ flag, make treats an error return just like success, except that it prints out a message that tells you the status code the shell exited with, and says that the error has been ignored. When an error happens that make has not been told to ignore, it implies that the current target cannot be correctly remade, and neither can any other that depends on it either directly or indirectly. No further recipes will be executed for these targets, since their preconditions have not been achieved. Normally make gives up immediately in this circumstance, returning a nonzero status. However, if the ‘-k’ or ‘--keep-going’ flag is specified, make continues to consider the other prerequisites of the pending targets, remaking them if necessary, before it gives up and returns nonzero status. 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. See Summary of Options. The usual behavior assumes that your purpose is to get the specified targets up to date; once make learns that this is impossible, it might as well report the failure immediately. The ‘-k’ option says that the real purpose is to test as many of the changes made in the program as possible, perhaps to find several independent problems so

However my Makefile below fails: $ cat Makefile all: -/bin/false ([ $$? -eq 0 ] && echo "success!") || echo "failure!" $ $ make /bin/false make: [all] Error 1 (ignored) ([ $? stop on error -eq 0 ] && echo "success!") || echo "failure!" success! Why does the Makefile above echo "success!" instead of "failure!" ? update: Following and expanding on the accepted answer, below is how it should be written: failure: @-/bin/false && ([ $$? -eq 0 ] && echo "success!") || echo "failure!" success: @-/bin/true && ([ $$? -eq 0 ] && echo "success!") || echo "failure!" make gnu-make share|improve this question edited Sep 5 '14 at 11:24 asked Sep 4 '14 at 15:13 Marcus Junius Brutus 99521429 You might want to investigate the .ONESHELL: directive. –Jonathan Leffler Feb 10 '15 at 14:54 add a comment| 3 Answers 3 active oldest votes up vote 8 down vote accepted Each update command in a Makefile rule is executed in a separate shell. So $? does not contain the exit status of the previous failed command, it contains whatever the default value is for $? in a new shell. That's why your [ $? -eq 0 ] test always succeeds. share|improve this answer answered Sep 4 '14 at 18:16 Kyle Jones 9,22011637 add a comment| up vote 2 down vote From the GNU make documentation: When errors are to be ignored, because of either a ‘-’ or the ‘-i’ flag, make treats an error return just like success, except that it prints out a message that tells you the status code the shell exited with, and says that the error has been ignore

... zero or more objects which can be coerced to character (and which are pasted together with no separator) or a single condition object. call. logical, indicating if the call should become part of the error message. domain see gettext. If NA, messages will not be translated. Details The error action is controlled by error handlers established within the executing code and by the current default error handler set by options(error=). The error is first signaled as if using signalCondition(). If there are no handlers or if all handlers return, then the error message is printed (if options("show.error.messages") is true) and the default error handler is used. The default behaviour (the NULL error-handler) in interactive use is to return to the top level prompt or the top level browser, and in non-interactive use to (effectively) call q("no", status = 1, runLast = FALSE). The default handler stores the error message in a buffer; it can be retrieved by geterrmessage(). It also stores a trace of the call stack that can be retrieved by traceback(). Errors will be truncated to getOption("warning.length") characters, default 1000. If a condition object is supplied it should be the only argument, and further arguments will be ignored, with a warning. Value geterrmessage gives the last error message, as a character string ending in "\n". Note Use domain = NA whenever ... contain a result from gettextf() as that is translated already.
