我想做类似的事情:
for i in *
do
if test -d $i
then
cd $i; make clean; make; cd -;
fi;
done
这很好用,但我想for
在构建损坏的情况下“打破”-loop。
有没有办法做到这一点?也许某种if
-statement,可以检查成功make
吗?
您可以使用 Make 本身来实现您正在寻找的内容:
SUBDIRS := $(wildcard */.)
.PHONY : all $(SUBDIRS)
all : $(SUBDIRS)
$(SUBDIRS) :
$(MAKE) -C $@ clean all
如果您的任何目标失败,Make 将中断执行。
支持任意目标:
SUBDIRS := $(wildcard */.) # e.g. "foo/. bar/."
TARGETS := all clean # whatever else, but must not contain '/'
# foo/.all bar/.all foo/.clean bar/.clean
SUBDIRS_TARGETS := \
$(foreach t,$(TARGETS),$(addsuffix $t,$(SUBDIRS)))
.PHONY : $(TARGETS) $(SUBDIRS_TARGETS)
# static pattern rule, expands into:
# all clean : % : foo/.% bar/.%
$(TARGETS) : % : $(addsuffix %,$(SUBDIRS))
@echo 'Done "$*" target'
# here, for foo/.all:
# $(@D) is foo
# $(@F) is .all, with leading period
# $(@F:.%=%) is just all
$(SUBDIRS_TARGETS) :
$(MAKE) -C $(@D) $(@F:.%=%)
您可以make
通过$?
变量检查其退出代码来检查是否已成功退出,然后有一个break
语句:
...
make
if [ $? -ne 0 ]; then
break
fi
