使文件语法错误 - 缺少分隔符

Question

我在下面第139行得到make文件错误,$(eval $(RULES)) 我对make文件语法缺乏经验.这是我输入make命令时给出的错误.

common.mak:139: *** missing separator.  Stop.

我试图通过单个空格删除选项卡,\ t无效.你知道原因是什么吗？

谢谢

我有同样的问题 - 在Windows上检查FFMPEG 但使用git.

运行后configure,当make我尝试运行时,我得到了相同的一行:

  common.mak:139: *** missing separator.  Stop.

正如@MadScientist所建议的那样 - Makefiles特别挑剔,不仅仅是tab(\ t),还有行结尾的选择(LF vs. CRLF).

这取决于GNU make命令,它必须运行它们 - 这似乎只是尊重LF.

所以*nix版本,如此,将起作用:

这是Windows下的同一个文件,不起作用:

(另一个赠品是它也更大,每行末尾的字节加倍!)

底线(可以这么说)是你可能需要重新格式化你的文件 - 也许是通过使用dos2unix命令.

即使不直接从git克隆,这仍然是这种情况 - 而是下载一个本身是从git clone创建的tar/zip.线的末尾将被保留.

或者,如果使用Git(就像我一样),你必须告诉它如何处理行尾字符.当它检出/克隆以及何时提交.

这里有一个完整的描述:http://adaptivepatchwork.com/2012/03/01/mind-the-end-of-your-line/

以及如何通过[core].eol设置配置(对于旧版本的git).

这在Windows上也很明显,如果您运行安装程序(例如http://git-scm.com/downloads),您将获得如下对话:

选择"按原样结帐,按原样提交"的最终选项为我修复了它.也许不是最原则的方式,但它迫使LF结尾被保留.

尝试配置ffmpeg时,我遇到了同样的问题make.使用当前版本的ffmpeg的主分支,问题出现在第160行的common.mak.

为了解决这个问题,我尝试了以下步骤:

• git config core.autocrlf false
• 删除所有*.mak文件
• git reset --hard

仅这些步骤并没有完全解决我的问题.根据有关TAB(\ t)字符的提示,我改变了第160行

至

注意在和之间的第160行的箭头(表示TAB).这个TAB为我解决了这个问题.我不得不将此更改更改为另一个文件.另一个文件有相同的错误消息.顺便说一下,Notepad ++是一个很好的工具,可以插入TAB以及更改行结尾.$(eval $(RULES))*.mak

由于ffmpeg需要一段时间才能建造,我决定分享我的解决方案......
