Linking Error compiling/Building Delphi XE7 & XE10 Android App (SQLITE3)

Question

I got a project from a former employee of our company.

It's an Android app written in Delphi XE7, using Android SDK 19 (4.4) and Sqlite3 for a local db on the smartphone.

For the moment we have a working copy on the smartphones, but I can't get it compiled/build on my pc. And we need a new version, because some things needs to change in our company logic.

I always get this fatal error:

 "[DCC Fatal Error] Linker error code: 1 ($00000001)"

Before this fatal error, i have more than hundred other erros, all looking almost the same:

[DCC Error] C:\Users\Public\Documents\Embarcadero\Studio\15.0\PlatformSDKs\android-ndk-r9c\toolchains\arm-linux-androideabi-4.6\prebuilt\windows\bin\arm-linux-androideabi-ld.exe: error: c:\\\\program files (x86)\\\\embarcadero\\\\studio\\\\15.0\\\\lib\\\\Android\\\\Release/libsqlite.a(sqlite3.o): multiple definition of 'sqlite3_aggregate_context'

Only the last 2 words of this errors are always different, so I assume this are all the different classes in sqlite3.

I tried a lot of things, from trying it in Xe7, XE8, XE10, different settings in the SDK Manager, ...

I made new projects and brought the files tp this new project, but I always got this same error.

My SDK Manager Settings are:

Can anyone give me a clue or a possible solution.

Thx in advance Timothy

Answer 1

I found the solution:

problem was that is used a SqliteUniProvider and in an other file there was still a dbxsqlite in the uses clause.

From the moment I commented the second one (dbxsqlite) out, the linking error dissapeared while compiling/building.
