[已解决]WSL+ubuntu18+kivy+Buildozer打包时 [WARNING]: lld not found 解决办法

 打包时遇到这个问题,其实是比较懵逼的. 网上收不到对应的帖子

[WARNING]: lld not found, linking without it. Consider installing lld if linker errors occur.

那么lld是啥呢
在https://lld.llvm.org/ 官网,  LLD is a linker from the LLVM project that is a drop-in replacement for system linkers and runs much faster than them. It also provides features that are useful for toolchain developers.
大致意思就是用lld build起来速度快很多.

Program	Output size	GNU ld	GNU gold w/o threads	GNU gold w/threads	lld w/o threads	lld w/threads
ffmpeg dbg	92 MiB	1.72s	1.16s	1.01s	0.60s	0.35s
mysqld dbg	154 MiB	8.50s	2.96s	2.68s	1.06s	0.68s
clang dbg	1.67 GiB	104.03s	34.18s	23.49s	14.82s	5.28s
chromium dbg	1.14 GiB	209.05s [1]	64.70s	60.82s	27.60s	16.70s

突然想试试能否用apt install lld一下. 结果真可以.如下:

安装过程中可以看出lld是和llvm是一起的
