Makefile中的变量用于存储字符串,这些字符串可以在Makefile的其他部分被引用。它们类似于其他编程语言中的变量,但通常更侧重于字符串处理。Makefile变量在赋值时不会自动扩展,除非使用了特定的扩展机制(如:=或=等)。 2. 如何在Makefile中定义变量 Makefile中定义变量的方式有几种,常用的有: =:基本的赋值操作符,...

In the install section of the main Makefile of kselftests, the echo command is used with -n flag, which disables the printing of new line due to which the output contains "\n" chars as follows: Emit Tests for alsa\nSkipping non-existent dir: arm64 Emit Tests for breakpoints\nEmit Te...

Steve's spandsp code includes some support for MMX and SSE2 optimisation. Define USE_MMX or USE_SSE2 in the Makefile to use this option. At this stage only the fir.h filter code is optimised, oslec would run much faster if lms_adapt_bg() in echo.c was also ported to MMX/SSE2. Wit...
