Question

如果我在我的Makefile中添加了评论（# ...），make会给我一个错误并退出。如果删除注释，makefile就可以正常工作。

Makefile:1: *** missing separator. Stop.

你的Makefile适合我（用标签替换空格），所以听起来你有一个流浪的非打印字符。

尝试检查“cat -vet Makefile”的输出。这将显示EOL，TAB和其他看不见的字符的位置。

你会想看到这样的东西：

# Backup Makefile$
#$
# Create backups from various services and the system itself. This$
# script is used to perform single backup tasks or a whole backup$
# from the system. For more information about this file and how to$
# use it, read the README file in the same directory.$
$
BACKUP_ROOT = /srv/backup$
ETC_PATH = /srv/config$
SVN_PATH = /srv/svn/$
TRAC_PATH = /srv/trac/sysinventory$
PR10_PATH = /swsd/project/vmimages/...$
PR10_MOUNT_PATH = /tmp/temp_sshfs_pr10$
$
MYSQL_USER = "xxx"$
MYSQL_PASSWORD = "xxx"$
$
$
DATE = `date +%F`$
$
help :$
^Icat README$
$
$
init-environment :$
^Imkdir -p $(BACKUP_ROOT)$
^Imkdir $(BACKUP_ROOT)/tmp$
^Imkdir -p $(PR10_MOUNT_PATH)$
$

确保所有命令都以“^I”开头。

您还可以尝试使用以下内容查找杂散字符：

cat -vet Makefile | grep "\^[^I]" --colour=auto

Answer 2

您可能已使用空格而非制表符来评论。请发布makefile，以便我们不必猜测。

Makefile无法理解评论
