Can not build out arm64 version for linux-android platform

[db0218]

• Version:
• Platform:
• Subsystem:

I try to build the ShadowNode sources with the guide:
https://github.com/yodaos-project/ShadowNode/blob/master/docs/build/Build-for-Android.md

I used exactly the same build config as the description in doc. But what I built out is arm-32 version, not 64.

The result of "file" command:
build/aarch64-linux-android/debug/bin/iotjs: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked (uses shared libs), BuildID[sha1]=799e3a8d0ab40f80600bfc07ba0760e10b251219, not stripped

My build steps:

export NDK_DIR=/home/tool/android-ndk-r21

./tools/build.py
--target-arch=aarch64
--target-os=linux-android
--cmake-param=-DANDROID_NDK=$NDK_DIR
--cmake-param=-DANDROID_NATIVE_API_LEVEL=23
--cmake-param=-DANDROID_ABI=armeabi-v7a
--cmake-param=-DANDROID_TOOLCHAIN=clang
--cmake-toolchain-file=$NDK_DIR/build/cmake/android.toolchain.cmake
--profile=./profiles/basic.profile

What error do you get from the above instructions?

No error found, it built out successfully.

IoT.js Build Succeeded!!

To run tests use '--run-test' or one of the folowing commands:

tools/testrunner.py /home/cchma/tool/ShadowNode/build/aarch64-linux-android/debug/bin/iotjs

Oops, I was misunderstood your question, may I ask you to print the options at https://github.com/yodaos-project/ShadowNode/blob/master/tools/build.py#L270, thus we could check if the config is correct.

[db0218]

pint the options at Line 270 in build.py

May I ask you to have a look at /home/cchma/tool/android-ndk-r21/build/cmake/android.toolchain.cmake?

[db0218]

It seems need to set the -DANDROID_ABI to arm64-v8a ? But After set --cmake-param=-DANDROID_ABI=arm64-v8a, the build will be failed.

lib/libjerry-core.a: error adding symbols: File in wrong format

This might be caused by the wrong format of some object files, have you tried a clean build?

Every time is clean build. First rm build -rf , then do build.

armeabi-v7a is 32 bit

[db0218]

The issue has been fixed. The "-DANDROID_ABI" should be "arm64-v8a" and the "-DANDROID_ABI" should also be added in the deps cmake files, otherwise these deps static libraries will all be arm32.
