Building Portola JDK11 for AMR64 arch

[Mikael Vidstedt]

It looks like the compiler doesn’t recognize the aarch64 instruction set, so configure probably picked up the wrong compiler. You’d have to double check what configure says it’s going to use.

However, even if you address that it’s unlikely to work. As you probably know Alpine uses the musl C library, so your cross compiler/devkit needs to be able to produce binaries for musl. The “-gnu” in your devkit path is a sign that it’s likely a devkit for the GNU C library. You’ll need to grab or create one for aarch64-linux-musl instead.

For completeness I’ll mention that I have not tried the musl port on anything other than linux_x64, but I can’t think of anything that wouldn’t work on linux_aarch64.

Cheers,
Mikael
