arm64-v8a architecture missing about gmp HOT 9 CLOSED

Actually I hasn't realized that arm64 support had been added to the NDK. I'll take a look at how feasible it would be.

from gmp.

Some ABI documentation is here:

And random stuff on StackOverflow:

I've added initial code into the arm64-v8a branch, but it isn't working. Somehow the autoconf build scripts don't like the new ABI.

from gmp.

Ah, turns out it was a couple of minor bugs in my build scripts. The arm64-v8a build now works and produces a shared object.

I have no hardware to validate this on, and at the moment no readily-available APK to try it out in the emulator. Sergey, please clone the repository and check out the arm64-v8a branch then validate that it works somehow.

from gmp.

Support is available in pull request 8.

I'll also add support for MIPS64 and AMD64 at some point.

from gmp.

Big thanks!

from gmp.

I added the x86_64 ABI build just now as well. No time at the moment to add support for MIPS64.

You could show your appreciation by confirming that this works on real/emulated hardware, or even writing a small APK test driver ;)
