ROOT/SUDO is required to run this script

[H4RUM4K1]

So I cloned the repo to my PC, get the MagiskONWSALocal folder, and everything inside it, and went to the scripts folder. I opened BASH here and type

$ ./build.sh -- arch x64 --release-type WIF  --magisk-ver stable --gapps-brand none --gapps-variant pico --remove-amazon --root-sol magisk

Somehow I've got the following error and can't find any solution to it online, can anyone please help me

bash.exe: warning: could not find /tmp, please create!

Before you do the command, "su" first.

Very sorry for being dumb. At first, I thought I have to install it on Windows like a normal app, but after reading through the guide again I realized that this is not built, and I have to build it myself on Linux before installing it on Windows. Thanks for the help

Yeah, the guide does not really tell you which things are done on the Linux side and which are done on the Windows side unless you are familiar with both.
