Thank you very much for taking this for a spin. Really appreciate the feedback - keep it coming!

I *think* (but see below) that’s same problem I "fixed” by explicitly installing sed or grep or something.. From your package list it looks like you do install grep, but you still run into the problem? Does installing sed help?


Out of curiosity, why did you have to do the poll.h softlink workaround? I was naively hoping I had fixed all of the incorrect includes, but maybe I missed something?

I believe this is the missing magic:

bash ./configure --host=x86_64-unknown-linux-musl --build=x86_64-unknown-linux-musl <…>

Specifically, the problem you’re running into is this guy:

http://mail.openjdk.java.net/pipermail/portola-dev/2017-April/000047.html <http://mail.openjdk.java.net/pipermail/portola-dev/2017-April/000047.html>

Basically you need to help the JDK build system/code understand that you’re building the musl version, because the library path workaround only kicks in with the musl build. I started looking into if/how we can automatically detect that, but for now you need to give it some manual CPR using —host and —build.

That package list is almost the same as the one I ended up with:

alsa-lib-dev bash cups-dev file freetype-dev g++ grep libx11-dev libxext-dev libxrender-dev libxt-dev libxtst-dev linux-headers make mercurial tar zip

Funnily enough I realize that ‘sed’ isn’t in my list here, and it seems to be working anyway.. I guess I need to go back and have a look at that at some point.

Looking forward to it!
