android - make 和 mka 有什么区别？

Question

所以我正在构建 TWRP。我看到有些人在构建恢复镜像时使用命令 make，例如make -j5 recoveryimage，但其他人使用 mka recoveryimage。

make 和mka 这两个命令有什么区别？我自己找不到全面的答案。

谢谢!

mka 旨在成为更快的make。这是一个很好的描述(source):

This little gem of a command is basically equivalent to a super-charged version of make. Make is the program that gets called to build our source, choosing the correct compiler for each part of the Android OS that we are making. Problem is, make is SLOW in its default configuration. It can take hours longer depending on your hardware. So what did they do? They mated make with a cheetah, and took their child mka. mka improves upon make by using the program sched_tool to make full use of all the threads available on your machine (For AMD, this is equivalent to the number of cores your processor has; For Intel, this is usually equivalent to twice the number of cores your processor has, due to HyperThreading). What this means is that ALL of your processor is working, not just one small part of it.
