Folkert de Vries (Aug 22 2022 at 18:55): Folkert de Vries (Aug 22 2022 at 18:55):does anyone on a windows machine want to pair on trying https://github.com/roc-lang/roc/issues/3840 sometime?
jan kili (Aug 22 2022 at 19:28):I have Windows 10 installed on a gaming computer that I don't use for coding - do you want to puppeteer me?
jan kili (Aug 22 2022 at 19:28):I could be available some day this week around sunrise Amsterdam time
Folkert de Vries (Aug 22 2022 at 19:36):apparently that is 6:30 here, which ... that's too early for me
Brian Carroll (Aug 22 2022 at 19:40):I could look at it with you if you like. Closer timezone too!
Brian Carroll (Aug 22 2022 at 19:41):Curious about the subject too, would like to understand windows executables a bit more

Folkert de Vries (Aug 24 2022 at 20:45):this worked out https://github.com/roc-lang/roc/pull/3893. however we found that getting roc to compile on windows is still quite a process (and involves manually deleting/commenting a bunch of stuff). We're making progress though!
Richard Feldman (Aug 25 2022 at 00:30):I just installed windows 11 on the new machine, so lmk if you'd like any non-wine testing!
Folkert de Vries (Aug 25 2022 at 07:02):Yes, https://github.com/roc-lang/roc/pull/3894 would make the build process much nicer if it works
Brian Carroll (Aug 25 2022 at 07:09):I have time now before work, I'll try that out.
Folkert de Vries (Aug 25 2022 at 19:56):that worked and is a good step forward. next, let's try and get cli to compile. If I remember correctly, it needs two things: define roc_alloc and friends in the cli crate, and disable roc_repl_expect because it uses unix-specific libc functions
Folkert de Vries (Aug 25 2022 at 19:56):https://github.com/roc-lang/roc/pull/3901/ tries to do that
Folkert de Vries (Aug 25 2022 at 19:57):I think you still need to disable the docs-related crates from the workspace (see https://github.com/roc-lang/roc/issues/3805)
Folkert de Vries (Aug 25 2022 at 19:57):the fix there may be very similar though: just define roc_alloc and friends in the docs crate and it should work
Brian Carroll (Aug 25 2022 at 21:14):Ok next chance I get, I'll give that a go
Folkert de Vries (Aug 27 2022 at 10:02):cargo build should now just work on windows, and even cargo run examples/platform-switching/zig-platform/rocLovesZig.roc
Folkert de Vries (Aug 27 2022 at 10:03):now, we need to fix all the problems. So it's very valuable for someone to just try it out and making notes of what fails and how.
Folkert de Vries (Aug 27 2022 at 10:04):I know there are some llvm tests that fail in llvm generation; I can try to tackle that just from linux
Folkert de Vries (Aug 27 2022 at 10:04):but I also observe some of our cli tests with zig platforms failing (e.g. examples/benchmarks/NQueens.roc) and it's unclear why from wine, so someone running that on windows would probably see more error info (or it just works there)
Folkert de Vries (Aug 27 2022 at 10:06):until it is merged, you need the changes to the host.zig from here https://github.com/roc-lang/roc/pull/3888/files to run the benchmarks on windows
