Hi @richard457, can you give specific reproduction steps? What are you doing to produce this error?

[richard457]

Create a simple flutter project, add amplify_storage_s3: ^2.4.1 and powersync: ^1.8.2 or any other plugin that uses sqlite3 the compile the app for windows, I think I checking in amplify_db_common and realized that we are using sqlite3 as name which will conflict with other sqlite3 packages out there

# The Flutter tooling requires that developers have a version of Visual Studio
# installed that includes CMake 3.14 or later. You should not increase this
# version, as doing so will cause the plugin to fail to compile for some
# customers of the plugin.
cmake_minimum_required(VERSION 3.14)

# Project-level configuration.
set(PROJECT_NAME "amplify_db_common")
project(${PROJECT_NAME} LANGUAGES C CXX)

# This value is used when generating builds using this plugin, so it must
# not be changed
set(PLUGIN_NAME "amplify_db_common_plugin")

add_library(${PLUGIN_NAME} SHARED

# Essentially, the idea of this build script is to compile a sqlite3.dll

Hi @richard457, our sincere apologies that you are still facing this issue. For clarification, you upgraded to the latest version 2.5.0 of amplify-flutter, yet nothing changed?.

[veganguy]

For clarification, you upgraded to the latest version 2.5.0 of amplify-flutter, yet nothing changed?.

That's correct - I have upgraded to amplify-flutter 2.5.0 and still get the same compile error on Windows, too. 🥺😢

[ekjotmultani]

Thank you @veganguy for the update. We will investigate further into this issue and the fix.

[veganguy]

Thank you, @ekjotmultani - we sincerely appreciate your assistance with this. 🙏🏽

[richard457]

Yes I upgraded to 2.5.0 and it is still the same.
