So it seems that docker is indeed somewhat working. I created a Windows docker file (currently it doesn’t include clang and I didn’t yet manage to actually test whether this can be used to build FDB). Do you think this would be a fruitful road to go down?
One of the drawbacks of the Windows (and macOS) build is that it’s hard to make it reproducible. This seems to work somewhat. For example this will give me a powershell prompt within a docker container that has msbuild, cmake, etc installed and in the path (the -m is super important because default is 1GB):
docker run -it --rm -v D:\develop:C:\develop -m 30GB fdb
Getting Docker on Windows working properly took me quite long, especially because it took me comically long to figure out that by default docker tries to run everything as a linux container and turns out you can’t install Windows in the Linux subsystem
