How to compile and install spatialite on iOS

Spatialite for iOS

Install compiler dependencies

brew install automake autoconf libtool libxml2 pkg-config
brew link libxml2

Build libspatialite

git clone https://github.com/gstf/libspatialite-ios.git
cd libspatialite-ios
make

The result is a folder, lib, containing several .a files, as well as an include folder containing many .h files.

Create a new XCode project

Copy the libspatialite binaries and "include" folder into a folder named "libspatialite" in the XCode project folder.

filesystem

In the XCode project's "Build Settings", you'll need to set the library and header search paths:

Library Search Paths: $(PROJECT_DIR)/AppName/libspatialite Header Search Paths: $(PROJECT_DIR)/AppName/libspatialite/include

search paths

Drag the .a files into your project.

From the "Build Phases" window, add the following to the section "Link Binary With Libraries":

  • libz.dylib
  • libxml2.2.dylib
  • libc++.dylib
  • libcharset.1.0.0.dylib
  • libiconv.dylib

XCode Project

Now you should be able to use spatialite! To test if everything worked, just make your AppDelegate output the spatialite version.

Add the following to AppDelegate.m

#include <sqlite3.h>
#include <spatialite/gaiageo.h>
#include <spatialite.h>

In your application:didFinishLaunchingWithOptions: method, add:

spatialite_init (0);
printf("Spatialite version: %s\n", spatialite_version());

Compile and run and you should see the version output in the console!
