multiple errors trying to build llvm from sources using ninja

[PavelKotov1]

Hello, dear friends!
I am not sure if it is a bug or something else, so please just bear with me since i am very new to the subject.
I am trying to build from sources and install llvm on windows 10. Installed all the prerequisites first.
Then: git clone https://github.com/llvm/llvm-project.git
cd llvm-project
mkdir build
cd build
cmake –G Ninja -DLLVM_ENABLE_PROJECTS=clang ../llvm
ninja
The output of the last command is as follows:

Could somebody help me figure out what is going on? And again i appologize in advance if i posted my question in the wrong area.
Thanks in advance!

Please, follow community guidelines to submit bugs in upstream LLVM project: https://llvm.org/docs/HowToSubmitABug.html

[PavelKotov1]

Please, follow community guidelines to submit bugs in upstream LLVM project:

Dear Alex, could you help me to figure out how to do that? There is SO much on that page that i am simply lost. As i said, i am new to llvm and pretty much have no idea where my issue belongs.
maybe you could just move my question where it needs to be?
Thanks in advance.

[alexbatashev]

@PavelKotov1 this repository is a fork by Intel of the upstream LLVM. We do not accept bug reports in the upstream project. believe the first four paragraphs from the link I provided explain how to submit a bug to LLVM.

[MrSidims]

Basically, here is a bug-report tool for llvm.org project: https://bugs.llvm.org/
Also you might subscribe and ask question in the special mailing list.

[PavelKotov1]

my question IS NOT a BUG REPORT.
IT IS A QUESTION.
BUT THANKS ANYWAY.

[WhateverKJA]

my question IS NOT a BUG REPORT. IT IS A QUESTION. BUT THANKS ANYWAY.

Please calm down. Everyone answered politely. This is not the place to ask questions about LLVM nor your LLVM build errors, do you understand that?

Furthermore you opened this issue as a bug, so...

Have a nice day.
