Makefile works in bash but fails in zsh. Can you point out error in syntax of for loop?

Here's the beginning of a GNUMakefile that works well under bash but has failed since I switched to zsh (and oh-my-zsh). It is annoying that I need to start a bash shell to perform it, so do you think you can help point out the syntax problem?

SUBDIRS = generator geometry io management physicslist processing


makeall:
        @echo "********************************************************************************"
        @echo " Building Project"
        @echo "********************************************************************************"
        @for dir in $(SUBDIRS); do (echo; echo; echo Building $$dir...; cd $$dir; $(MAKE) "SUBDIRS=$(SUBDIRS)"); done

This results in an infinite loop:

[●]% make
********************************************************************************
 Building Project
********************************************************************************


Building generator...
/bin/sh: line 0: cd: generator: No such file or directory
********************************************************************************
 Building Project
********************************************************************************


Building generator...
/bin/sh: line 0: cd: generator: No such file or directory
********************************************************************************
 Building Project
********************************************************************************
...
...

It seems I fork-bomb myself with make's and /bin/sh's:

...
...
24921 ttys012    0:00.00 make SUBDIRS=generator geometry io management physicslist processing
24925 ttys012    0:00.00 /bin/sh -c for dir in generator geometry io management physicslist processing; do (echo; echo; echo Building $dir...; cd $dir; make "SUBDIRS=generator geometry io man
24926 ttys012    0:00.00 /bin/sh -c for dir in generator geometry io management physicslist processing; do (echo; echo; echo Building $dir...; cd $dir; make "SUBDIRS=generator geometry io man
24927 ttys012    0:00.00 make SUBDIRS=generator geometry io management physicslist processing
24931 ttys012    0:00.00 /bin/sh -c for dir in generator geometry io management physicslist processing; do (echo; echo; echo Building $dir...; cd $dir; make "SUBDIRS=generator geometry io man
24932 ttys012    0:00.00 /bin/sh -c for dir in generator geometry io management physicslist processing; do (echo; echo
...

EDIT:

The makefile inside of generator looks like:

name := generator

include ../ProgramConfig/Libraries.gmk

Libraries.gmk looks like

.PHONY: all lib
all: lib

inclu开发者_如何学Gode ../ProgramConfig/BuildDirs.gmk

include $(G4INSTALL)/config/architecture.gmk
include $(G4INSTALL)/config/common.gmk

include ../ProgramConfig/ExtraDeps.gmk
include ../ProgramConfig/GEANT4.gmk

# Add the sub-directory include directories to the compilation list
CPPFLAGS += $(addprefix -I../, $(addsuffix /include, $(SUBDIRS))) -O2

cleanup:
    cd $(G4WORKDIR)
    rm -rf bin tmp lib

Experiment 1. Try this:

makeall:
    @for dir in $(SUBDIRS); do (echo Building $$dir...; cd $$dir; $(MAKE) "SUBDIRS=$(SUBDIRS)" ; cd -); done

And the safer method I had in mind: iterate in Make, not in the shell.

makeall: $(SUBDIRS)

.PHONY: $(SUBDIRS)

$(SUBDIRS):
    @echo Building $@
    @cd $@; $(MAKE) "SUBDIRS=$(SUBDIRS)"

Note that you can also make that last rule a little cleaner:

$(SUBDIRS):
    @echo Building $@
    @$(MAKE) -C $@ "SUBDIRS=$(SUBDIRS)"
