Makefile無法理解評論

Question

如果我在我的Makefile中添加註釋（# ...），make會給我一個錯誤並退出。如果我刪除評論，makefile工作正常。

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

• 製作版本：3.81
• Linux操作系統：Ubuntu 9.04的

的Makefile文件：

# 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.

PR10_MOUNT_PATH = /tmp/temp_sshfs_pr10 

MYSQL_USER = "xxx" 
MYSQL_PASSWORD = "xxx" 


DATE = `date +%F` 

help : 
     cat README

你的Makefile適用於我（用空格替換爲製表符），所以它聽起來像你有一個流浪的非打印字符的情況。

嘗試檢查「cat -vet Makefile」的輸出。這將顯示EOL，TAB和其他看不見的字符。

你會希望看到這樣的事情：

# 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 $(PR10_MOUNT_PATH)$ 
$ 

確保所有命令都通過「^I」開頭。

你也可以嘗試使用類似走失字符：

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

您可能使用空格代替製表符的評論。 請發佈makefile，以便我們不必猜測。
