Makefile无法理解评论

你的Makefile适合我(空格被标签取代),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方法查找杂散字符:

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