How do I use Sqlite in a dylib in an i386 app in XCode 4? This approach does work in iPhone app

Using Sqlite in a dylib in an i386 app in XCode 4

For iOS I needed to add a file namely libsqlite3.0.dylib from directory: /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/usr/lib/

I have a method that obtains and MaxID from a column of an sqlite DB. This works fine in a universal iOS app I made. I want to port this code over to a Mac app i386.

Because I could not find such an dylib for i386, I created one using the download file: sqlite-autoconf-3070500.tar.gz

Following directions I produced 3 files in /usr/local/lib

libsqlite3.a libsqlite3.la libsqlite3.dylib

In XCode I have add '/usr/local/lib' to the Build Setting->Search Paths->Library Search Paths

I have used: export DYLD_LIBRARY_PATH=/usr/local/bin/:$DYLD_LIBRARY_PATH

I get the following build error when I uncomment the sqlite code in AppDelegate.m

Thanks so much for reading this. Please advise. Mark

Solution

  • I'd link against the SQLite dylib shipped in the SDK, which is at /Developer/SDKs/MacOSX10.6.sdk/usr/lib/libsqlite3.dylib (substitute your target SDK as needed).
