如果<variable>是一个环境变量,并且当Makefile被执行时,“-e”参数没有被打开。 “file” 如果<variable>这个变量被定义在Makefile中。 “command line” 如果<variable>这个变量是被命令行定义的。 “override” 如果<variable>是被override指示符重新定义的。 “automa
如果<variable>;这个变量被定义在Makefile中。 “command line” 如果<variable>;这个变量是被命令行定义的。 “override” 如果<variable>;是被override指示符重新定义的。 “automatic” 如果<variable>;是一个命令运行中的自动化变量。关于自动化变量将在后面讲述。 这些信息对于我们编写Makefile是非常有...

The configure script basically consists of many lines which are used to check some details about the machine on which the software is going to be installed. This script checks for lots of dependencies on your system. For the particular software to work properly, it may be requiring a lot of...
62 # CONFIG_USE_TINY_PRINTF is not set 63 CONFIG_REGEX=y 可以看出.config文件中都是以“CONFIG_”开始的配置项,这些配置项就是Makefile中的变量,因此后面都跟有相应的值,uboot的顶层Makefile或子Makefile会调用这些变量值。在.config中会有大量的变量值为‘y’,这些为‘y’的变量一般用于控制某项功能是否...
176 KBUILD_CHECKSRC=0 177 endif 7、模块编译 Linux允许单独编译某个模块,使用命令“make M=dir”即可,旧语法“make SUBDIRS=dir”也是支持的。顶层Makefile中的代码如下: 示例代码35.5.7 顶层Makefile代码段 179 # Use make M=dir to specify directory of external module to build ...
When Make starts, it automatically creates Make variables out of all the environment variables that are set when it's executed. # Run this with "export shell_env_var='I am an environment variable'; make"all:# Print out the Shell variableecho $$shell_env_var# Print out the Make variable...

Once your make path is properly set, accept the prompt to allow Makefile Tools to configure IntelliSense. If you don’t see that notification, or you accidentally dismissed it, you can grant Makefile Tools permission to configure IntelliSense by running “C/C++: Change Configuration Provider”...
