Building wxWidgets for iOS

wxiOS is far from a full supported port, but can be used as base for simple applications and future improvements.

It requires Xcode with iOS SDK 9.0 or later. Xcode is available for free in the OS X app store.

To build wxiOS you should use Xcode to open the minimal samples Xcode project file located at:

samples/minimal/minimal_iphone.xcodeproj

That project files includes wxiphone.xcodeproj so you just need to hit run in order to see the minimal sample running in the simulator.

The library can also be build via configure/make:

mkdir build_ios
cd build_ios
../configure --with-osx_iphone --enable-monolithic \
    --with-macosx-version-min=8.0 --disable-shared \
    --enable-macosx_arch=i386 \
    --with-macosx-sdk=$(xcrun --sdk iphonesimulator --show-sdk-path)
make
