@taylor on windows 10, invoking clj.native-image is giving the following here:

this is via: clj -A:native-image for https://github.com/sogaiu/adorn -- any hints how i might investigate possible causes?

How are you specifying the path to Graal?

taylor21:08:22

I could definitely add some validation code that gives a more useful error in this case

sogaiu21:08:20

ah, thanks -- i did not have GRAALVM_HOME set, nor native-image in my PATH. my bad. thanks for your help!
