No ocaml-android for 64 bit? (compiling to arm64 failing)
Following the readme, I did
opam switch 4.04.0
eval `opam config env`
and then did the configure line for aarch64, but at opam install ocaml-android, I get an error indicating that ocaml-android is only compatible with a 32 bit system. (and ocaml-android is just a symlink to ocaml-android32)
Is the readme wrong?
When I try to configure for aarch64 using 4.04.0+32bit, I get a segfault when trying to run the resulting binary.
I get an error indicating that ocaml-android is only compatible with a 32 bit system. (and ocaml-android is just a symlink to ocaml-android32)
Correct. Back when I started this project there was no ARM64 Android. So there is still no support for it.
Ok, good to know! I was confused because it looked like @yunxing had gotten in working over in #25, and I couldn't figure out what I was doing wrong.
Try change symlink to ocaml-android64 if there is any? In theory this project should be able to work with 64 bit system and I'm pretty sure I got it working for aarch64 at some point, although we ended up shpping the 32 version.
If that doesn't work, consider building an Android app with 32 version if performance is not a bottleneck.
Copy the ocaml-android32 package to ocaml-android64, fix up the contents, add a dependency from ocaml-android to ocaml-android64... and please send a PR :)
Hey Guys, Sorry to bother you...
Do we now have support for ocaml-android64 ?
I need this to cross-compile facebook/flow for aarch64 on x86_64 machine.
Regards,
I don’t believe 64-bit builds in the opam-cross-android. I added 64-bit support in this fork:

@markghayden Hi Mark,
Thanks for quick support 😄
Can you please help me out regarding "how to use your toolchain" to compile facebook/flow package.
I am sorry, I am naive to this Ocaml world...
Regards,
Especially how to execute that configure line.
ARCH=arm64 SUBARCH=arm64 SYSTEM=linux_eabi \
CCARCH=arm64 TOOLCHAIN=aarch64-linux-android-4.9 \
TRIPLE=aarch64-linux-android LEVEL=24 \
STLVER=4.9 STLARCH=arm64-v8a \
opam install conf-android
How and where to execute the above commands as I am unable to locate configure script in my .opam directory?
This is what I am getting when I executed opam install ocaml-android --debug

@akhilgupta74 did you execute the ARCH=amd64 .... command? That needs to be done first
