Android NDK Build Error

[subu1979]

[utelle]

For ARM architectures the source code includes the header file arm_neon.h (resp arm64_neon.h) depending on certain preprocessor symbols (namely _M_ARM resp _M_ARM64). Looking at your screenshot of the error messages I get the impression that the header file arm_neon.h you are using does not define several of the NEON intrinsics. However, since you are not giving any version information of the tools you are using I have absolutely no idea why.

Maybe you are using outdated tools, maybe you did not specify all necessary preprocessor symbols.

All I can say is that using the Android build instructions provided by the SQLite project (see top 2 "Building a Custom aar File") work for me flawlessly (after adjusting the file Android.mk and adding the SQLite3MC source amalgamation).

Thank you.

[utelle]

Thank you.

You are welcome. Could you solve your problem? If yes, how? Other developers might have had similar issues.

Unable to compile sqlite3mc
I'am able to compile sqleet & original sqlite3 (http://www.sqlite.org/android android.fossil)

Sqlite3 Cross-Compilation

If you don't mind can you share your Android.mk file

[utelle]

When I compile the Android bindings for SQLite3MC I perform the following steps:

1. Download and extract SQLite Android Bindings from official SQLite site
2. Replace sqlite3.c and sqlite3.h in subdirectory ./sqlite3/src/main/jni/sqlite by sqlite3mc_amalgamation.c and sqlite3mc_amalgamation.h
3. Replace Android.mk in subdirectory ./sqlite3/src/main/jni/sqlite by Android.mk (adjusted Android.mk file, rename downloaded file to Android.mk)
4. Execute commands as described in section 2.3 of SQLite Android guide:

$ export ANDROID_HOME=~/Android/Sdk/
$ cd sqlite3
$ ../gradlew assembleRelease

Building succeeds only for "Build sqliteX_armeabi-v7a"

[utelle]

Unfortunately I'm not able to reproduce the problems you experience.

Did you apply any further changes to the build files? For example, you seem to use a different NDK version than that that is referenced in the original SQLite Android files.

[utelle]

I'm going to close this issue for now, because I can't reproduce the problem. For me the Android build works without any issues. Therefore I suspect that something is wrong with your environment or that you applied some unmentioned changes causing the problem.

If you still feel that this project is to blame for the problem, you have to provide more detailed information (versions and settings of the tools you are using, and so on).

[Nailik]

I can reproduce the issue with the errors
error: assigning to 'uint8x16_t' (vector of 16 'uint8_t' values) from incompatible type 'int'
when using android ndk above 23.

• ndkVersion '23.2.8568313' (works)
• ndkVersion '24.0.8215888' (errors)
• ndkVersion '25.1.8937393' (errors)
  I supressed all waarnings by using

@Nailik Thanks for testing. I have to admit that I hadn't installed NDK version 25 in my test environment. Indeed it works for NDK versions up to 23, but not for higher ones.

I compared the include files arm_neon.h of version 23 and 25, and in fact there is a difference: Up to version 23 the required functions are defined, if the symbol __ARM_FEATURE_CRYPTO is defined, but for higher versions the symbol __ARM_FEATURE_AES is checked.

Defining the symbol __ARM_FEATURE_AES by adding the line

#define __ARM_FEATURE_AES 1

after line 259095 of sqlite3mc_amalgamation.c

#define __ARM_FEATURE_CRYPTO 1

should fix the issue. Could you please confirm? TIA.
