Very new to Crystal, Added shard "zstd" and just wanted to see if it had gone right, got this:

PS J:\code\crystal\ztest> crystal build ztest.cr

I've attached the directory. Sorry if I did this wrong, just following the directions on the screen.

I'd wager a guess that that lib just doesn't have support for Windows as it worked fine for me on linux:

$ shards install
Resolving dependencies
Fetching https://github.com/didactic-drunk/zstd.cr.git
Installing zstd (1.2.0)
Postinstall of zstd: ./build/zstd_install.sh
Writing shard.lock
$ crystal ztest.cr
hi

I'd maybe open something on that repo. However, we could also probably handle this scenario better as to not make people think it's a compiler bug?

Error seems to be coming from https://github.com/didactic-drunk/zstd.cr/blob/6e63bfcc80fb7ee14019216c1bf5839f09c7120f/src/zstd/lib.cr#L2, which is using a shell script as a way to build out the link flags.

Yeah, the root cause is that the shard doesn't support Windows.
But this should lead to a normal compiler error, it's not a bug in the compiler.
