Building LDC on windows, woe is me!

Ok been banging my head against this for a few hours and getting nowhere. Following the windows build instructions up to the point of generating NINJA build files...

cmake -G Ninja ..\ldc -DCMAKE_INSTALL_PREFIX="C:\LDCDEV\LDC-x64" -DCMAKE_BUILD_TYPE=RelWithDebInfo -DLLVM_ROOT_DIR="C:/LDCDEV/LLVM-x64"

gives me this...

============

It works with the MVSC 2019 generator, but I have no idea why it wont generate the NINJA build files. I tried running it from the VS Developer Command prompt, and that doesnt work either, different error messages, and looks like it might be trying to link to x86 libs instead of x64, but cant seem to figure out how to change that.

disclaimer: total newbie on CMAKE, build scripts, etc...

Thanks, I managed to get it all to work, I had to build llvm from scratch as you suggest.

There were a few other things tripping me up but I got there in the end. I just deleted everything and ran though the instructions more carefully. With what I learned from the first try it all went smoothly.

Making sure everything was "run as administrator" was probably the main issue. Like for some reason if I forgot to run the shell as administrator, CMAKE would run, but it would error out on odd things. Like it would detect the compilers, but not the compiler ABI.

You might be the only individual in the universe who have made it.

Can you post some build scrips and setup for how you got everything to work?

I followed the instructions to the letter, same folder names, one step at a time, from here...

https://wiki.dlang.org/Building_and_hacking_LDC_on_Windows_using_MSVC

I had to ensure the command prompts were always run as administrator. It gave odd error messages if I forgot to do that.

I did it on a fresh install of windows 10, with a fresh install of VS2017, I literally tried to replicate everything listed in the instructions.

IIRC The only thing I had to do extra was passing "-DD_COMPILER=c:\path\to\ldmd2.exe." to ninja, it's listed in the section "Building LDC" but doesn't really tell you why you might need it.

I'm not 100% sure that's all there was to it but if you can't get it to work I can always have a run at it again and keep notes of exactly how I got it to work.
