Makefile无法理解评论

本文介绍了Makefile无法理解评论的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

如果我在Makefile中添加注释(# ...)，则make给我一个错误，然后退出.如果删除注释，makefile会正常工作.

If I put comments (# ...) in my Makefile, make gives me an error and quit. If I remove the comments, the makefile works fine.

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

推荐答案

您的Makefile对我有用(用制表符代替空格)，因此听起来好像您遇到了一些杂乱的非打印字符.

Your Makefile works for me (with spaces replaced by tabs), so it sounds like you have a case of stray non-printing chars.

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在哪里.

Try inspecting the output of "cat -vet Makefile". That will show where EOL, TAB and other unseen chars are.

您将希望看到以下内容:

You'll want to see something like this:

# 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 $(PR10_MOUNT_PATH)$ $

确保所有命令均以"^I"开头.

Make sure all commands are preceeded by "^I".

您还可以尝试使用类似以下内容的流浪字符:

You could also try to looking for stray chars using something like:

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