[cfe-dev] Building Clang on Windows

Did you use the 64-bit hosted compiler? (I think Clang's instructions should be rewritten to assume VS 2017 and 64-bit hosting, instead of saying it's optional.)

Hello everyone,

This week I tried to use clang on my windows setup and was very happy to see how the site invited people to get involved and contribute to the project.

With this in mind I tried to build clang following the instructions here<https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fclang.llvm.org%2Fget_started.html&data=02%7C01%7Cstl%40exchange.microsoft.com%7Cf5b43d9b24cc41afcf8108d629512a61%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C636741825921297608&sdata=vjX9cIbH21gM5nj8Or2rEv5QLmub74e3I7kiXQdR%2BbU%3D&reserved=0> and everything went fine until I actually tried to compile the clang project using visual studio. I got a compiler is out of heap space error which surprised me as I had previously built big projects such as the Dolphin Emulator without a problem.

I detailed some of my failed attempts to fix this issue in this SO question<https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fstackoverflow.com%2Fquestions%2F52628064%2Fbuilding-clang-on-windows-memory-usage&data=02%7C01%7Cstl%40exchange.microsoft.com%7Cf5b43d9b24cc41afcf8108d629512a61%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C636741825921297608&sdata=Lc37LhErZm5eU%2Fpcp45qmVeynBLKklcjuhR%2F5fNejf0%3D&reserved=0>. Do you have any suggestions?

Best regards,
Fabio Picchi
