【问题描述】:
我正在尝试为 os161 构建用户空间。当我在命令行中输入 make 时,出现以下错误:
Makefile 24: ***缺少分隔符(您的意思是 TAB 而不是 8 个空格?)。停下来。
我在第 24 行检查了 Makefile,并尝试在行首添加一个 TAB,但这没有奏效,因为我得到了另一个错误:
Makefile 24: ***recipe 在第一个目标之前开始。停下来。
这是完整的 makefile 供参考:
#
# Toplevel makefile for OS/161.
#
#
# Main rules:
# all (default): depend and compile system; install into staging area
# rebuild: likewise, but start with a clean slate.
# fullrebuild: likewise, but start with a very clean slate.
#
# What all does, in order:
# tools: depend and compile the tools used in build.
# includes: install header files.
# build: depend and compile the system.
#
# Other targets:
# depend: just update make dependency information.
# tags: generate/regenerate "tags" files.
# install: install into $(OSTREE).
# clean: remove generated files.
# distclean: remove all generated files.
#
TOP=.
.include "$(TOP)/mk/os161.config.mk"
all:; # make this first
MKDIRS=$(OSTREE)
.include "$(TOP)/mk/os161.mkdirs.mk"
all: tools .WAIT includes .WAIT build
rebuild:
$(MAKE) clean
$(MAKE) all
fullrebuild:
$(MAKE) distclean
$(MAKE) all
# currently no tools required, hence no tools/ dir or work to do
tools:
@true
build:
(cd userland && $(MAKE) build)
(cd man && $(MAKE) install-staging)
(cd testscripts && $(MAKE) build)
includes tags depend:
(cd kern && $(MAKE) $@)
(cd userland && $(MAKE) $@)
clean:
(cd kern && $(MAKE) $@)
(cd userland && $(MAKE) $@)
rm -rf $(INSTALLTOP)
distclean: clean
rm -rf $(WORKDIR)
install: $(OSTREE)
(cd $(INSTALLTOP) && tar -cf - .) | (cd $(OSTREE) && tar -xvf -)
.PHONY: all rebuild fullrebuild tools build includes tags depend
.PHONY: clean distclean
# old BSD name, same as distclean
cleandir: distclean
.PHONY: cleandir
问题(24)是:
.include "$(TOP)/mk/os161.config.mk"
任何帮助将不胜感激。我检查了类似的 makefile 错误,但似乎找不到问题所在。
【问题讨论】:
-
该行至少应在
all:行之后 -
仍有缺少分隔符的错误。试着把所有:;在第 24 行之前。
-
我解决了这个问题,它与 makefile 语法没有任何关系。我的默认 make 是 GNU make,我不得不改用 BSD make。
-
您的
Makefile使用的是什么编辑器?一些编辑器需要专门配置以允许插入 tab 字符
