mysql for building on iOS

mysql-ios

This repo is a convenience project for building mysql for iOS (in particular mysqlclient). It contains the mysql source at version 8.0.12 and generated/modified XCode project for building mysqlclient for iOS.

Building

Building libmysqlclient for iOS is not super straight forward since the bundled cmake configuration is only intended for generating an XCode project for macOS; as a result, there are a number of targets that are only intended for macOS (eg. com.apple.product-type.tool targets that cannot be build for iOS).

The included build_ios/MySQL.xcodeproj has been generated using the cmake configuration that mysql comes with, and then modified to support building (still a somewhat manual process) for iOS. See below for details on how the XCode project was setup.

To build, first build the GenError target using the macOS SDK, then build mysqlclient-nogenerr for iOS. If you would like to build a fat library that support both devices (arm) and the simulater (x86_64) you can use lipo -create to merge individual builds for each platform.

Manual Configuration

The XCode project and build artifacts are created by the following process:

1. cmake -G Xcode to generate the XCode project.
2. Update the XCode project to build for iOS (changing the base SDK and target platforms from macOS to iOS).
3. Create a clientlib-nogenerr target that is a duplicate of clientlib, but without the target dependency for GenError.
4. Create a mysqlclient-nogenerr that is a duplicate of mysqlclient but with clientlib-nogenerr replacing clientlib.

The overall idea here is to just take the existing build targets and just build them for iOS, comp_err is used to generate the errors and will be run in the GenError target, and thus should still be built for macOS.

Prebuilt Static Libraries
