6 months ago Thanks for your interest in the project.
This project intends to raise Linux (i.e., ELF) binaries (see current status of project) and has no functionality that raises Windows (i.e., PE/COFF) binaries.
If for some reason you do wish to build it on Windows (such as to raise ELF binaries or some other), this document provides details to build LLVM on Windows. Consequently, CMake variables specified in step 4 of Linux build instructions would most likely need to be modified accordingly.
I'm trying to get this running, but CANNOT get step 4 to work. I'm on a Windows 11 box.
I have multiple versions of VS installed, I've been a VS developer for decades. 2015, 2017, 2019, 2022. I generally always do full installs. I have numerous ASM installed, but do I have the right one? I don't know. I have a couple of C compilers installed, but do I have the right one? I don't know. Nothing is telling me how to get past these errors. The error tells me to set environment variables, but that's not working. Since that's not working, I think I maybe have the wrong ASM/C compilers installed.
Is it possible to find out what the preferred ASM/C compilers are, so I can get them installed, and the environment variables set right to get this working?
I really think there are at least 10 steps between #3 and #4 that were just skipped/assumed. Here's what I am seeing
