Is this using rust-ndk?

worldly heath
#

The problem is because you are cross compliling from x86 to arm and it openssl-sys couldn't find the right version of openssl

#

You can link to an openssl built for arm by setting $Env:OPENSSL_DIR = "/path/to/aarch64-linux-android"

#

or setting openssl-sys to use the vendored feature which should try to build Openssl for the target arch automatically

#

You can do this by setting openssl = { version = "*", features = ["vendored"] } in your cargo.toml or most crates that require openssl have a vendored feature flag you can use

#

Let me know if that works or you have any other questions. I just spent like a week digging into openssl-sys to get it to cross compile from windows -> andriod lol 😅

worldly heath
#

Was that with setting OPENSSL_DIR or vendored feature

#

I'm not 100% sure. I think it might be

#

do you have libssl-dev installed?

#

on Ubuntu

#

I'm not 100% what missing. I feel like it should be installed. I'll google some and see

worldly heath
#

I haven't found out exactly what it is. Looks like the build-script is missing that program for compiling openssl on linux but not sure where it comes from. Maybe the android ndk but not 100% sure

#

Not sure you might have more luck building openssl manually for android and linking to it export OPENSSL_DIR="openssl_arm64-android"

#

here's one i compiled if you want to test it out. Remember to remove the openssl = { version = "*", features = ["vendored"] } from your cargo.toml or it'll keep trying to build it manually

#

Ok i'll let you know if I think of anything else

#

This error is saying the OPENSSL_DIR environment variable wasn't set

worldly heath
#

if you run printenv does it show up?

#

Yeah it's super weird because its saying OPENSSL_DIR unset in the error msg but in your example you set it and printenv is showing it set

#

cargo build --target=aarch64-linux-android

#

can you try building it manually by running the above cargo command instead of cargo mobile android run

#

rustup target add aarch64-linux-android

#

might help if you haven't got it installed yet

#

ok thats good

#

really weird I feel like it should work.

#

It took me like a week to get openssl working with android. Maybe I forgot a change I made to my system.

#

Yeah the android is a mess and such a pain to get setup 🤣

#

can you post the full error msg

#

I think i found it.

#

In my path (on windows）I have

#

D:\androidsdk\ndk\25.2.9519653\toolchains\llvm\prebuilt\windows-x86_64\bin\

#

which has aarch64-linux-android-clang in it

#

You just need to find where it is on your system. It should be in your android ndk install

#

yeah

#

Good luck i hope this works haha

#

no worries take your time

#

the error with cargo mobile android run is still that its not finding the OPENSSL_DIR variable. Probably something with gradle not picking it up not sure

#

the first error seems to be with the package I sent you. It might not be right

#

running vcpkg install openssl:arm64-android

#

I'm also going for dinner now. I'll check more later

worldly heath
#

yah its 7pm or me haha

#

is aarch64 and arm64 the same? I thought they were but maybe not

worldly heath
#

I would try installing vcpkg and creating it yourself

#

It seems something is wrong with the cross compiling and linking

worldly heath
#

I'm away from my computer right now but if you check the /config-arm64-android-rel-err.log
it'll say you have to set an env variable to link to the android ndk

#

I forget the name off the top of my head

worldly heath
#

I won't be back at my computer for another 3-4 hours.

#

I feel like it should be working. But hopefully after you compile on your device it should link correctly

#

We can also try using the google pixel emulator which uses x86. Thats the one I'm using for testing so I know I have a working openssl for that

worldly heath
#

ANDROID_NDK_HOME = "D:\androidsdk\ndk\25.2.95196" is the env variable you have to set for vcpkg

#

ANDROID_NDK_HOME

#

Went through getting android stuff setup today

#

I was able to get it fixed but we will have to wait for the fix to be merged before releasing
