后面的几行不要用tab。
#2
不行啊，一样
#3
搜“跟我一起写makefile”？
#4
能告诉我第几章第几节吗？
#5
搜“makefile 续行符”？
#6
我的例子里不是用了续行符吗？难道还有别的用法？阁下要是知道的话请直接告诉我。

Commands in a Makefile
Home Page (Projects) | Overview (NMAKE Reference) | How Do I... Topics (Projects)
A description block or inference rule specifies a block of commands to run if the dependency is out-of-date. NMAKE displays each command before running it, unless /S, .SILENT, !CMDSWITCHES, or @ is used. NMAKE looks for a matching inference rule if a description block is not followed by a commands block.
A commands block contains one or more commands, each on its own line. No blank line can appear between the dependency or rule and the commands block. However, a line containing only spaces or tabs can appear; this line is interpreted as a null command, and no error occurs. Blank lines are permitted between command lines.
A command line begins with one or more spaces or tabs. A backslash ( \ ) followed by a newline character is interpreted as a space in the command; use a backslash at the end of a line to continue a command onto the next line. NMAKE interprets the backslash literally if any other character, including a space or tab, follows the backslash.
A command preceded by a semicolon (;) can appear on a dependency line or inference rule, whether or not a commands block follows:
project.obj : project.c project.h ; cl /c project.c
