Using Isthmus Tool

[Vibhatha Abeykoon]

Hello, 

I am using a very old version of `isthmus` from this PR: https://github.com/substrait-io/substrait/pull/120

Since the up-to-date work is here: https://github.com/substrait-io/substrait-java

I am curious whether this can be built on a Mac M1? I previously tried the old version on Ubuntu. In general is there a guideline on the version specifications, setup on Mac, Ubuntu? Or does it need to be documented?

 

Best, 

Vibhatha

Hi,

No experience with Mac, but I would assume that it would work there just the same as on Linux. The command I've been using to build is "./gradlew nativeImage" in the root directory of substrait-java, which should generate a binary at isthmus/build/graal/isthmus.

AFAIK there is no documentation yet; it also took me a while to figure that command out. I'd write it, but I have never used gradle or graal beyond building and running Isthmus, and haven't written Java in over a decade. Probably better if someone who knows what they're doing does it :)

Regards,

Jeroen

Hello Jeroen, 

Thanks for the detailed explanation. Since I couldn't find more from the dev docs, I was also looking into the CIs[1] to figure it out. But I saw the CI supports Ubuntu and Mac [2], but is this supported on Mac M1? Though, I will give it a try. But if someone already has a guideline (personal use), it would be a great help if it can be documented.

Previously, in the older repo, somehow I just naively got it built as gradle build docs says and it worked fine. Beyond that, my knowledge is very limited on Gradle usage.

Appreciate your insight!
