用MS NMAKE打印较长的编译行

本文介绍了用MS NMAKE打印较长的编译行的处理方法，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

我有一个旧版MS NMAKE Makefile，我需要修复其中的一些错误.

I have a legacy MS NMAKE Makefile I need to fix a few bugs in.

我想调试一些非常长的命令行，这些命令行正在使用内联文件" :

There are some very long command lines I wish to debug that are being executed using the NMAKE trick of "inline files":

dep:
    cmd @<<tmpfilename
cmd_args..
<<

将行更改为

dep:
    echo cmd @<<tmpfilename
cmd_args..
<<

NMAKE抱怨该行太长.

NMAKE complains that the line is too long.

我还可以使用其他技巧来查看NMAKE实际执行的命令行吗?

Is there any other trick I can apply in order to view the command line NMAKE is actually executing?

推荐答案

为保留用于保留命令行的临时文件，请在最终<<之后附加KEEP关键字.例如

In order to keep the temporary file that keeps your command line append the KEEP keyword after the final <<. For example

dep:
    echo cmd @<<tmpfilename
cmd_args..
<<KEEP

在这种情况下，发出nmake dep后，将保留一个名为tmpfilename的文件，并保留参数列表cmd_args.

In this case after issuing nmake dep a file named tmpfilename will remain, and hold the arguments list cmd_args.

请参阅此. 此，此(警告:PDF)是KEEP和NOKEEP关键字的说明，但是我不确定它们是否专门针对MS NMAKE编写.

See sample makefile 2 in this MS KB article. This and this (warning:PDF) are explanation of the KEEP and NOKEEP keyword, but I'm not sure if they were written specifically for MS NMAKE.
