Question

i just tried to create a database in my iPhone app and couldn’t build it.
i used following tutorial: tutorial

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *docsPath = [paths objectAtIndex:0];
    NSString *path = [docsPath stringByAppendingPathComponent:@"database.sqlite"];
    FMDatabase *database = [FMDatabase databaseWithPath:path];
    [database open];

but when running the app i get following error message:

Undefined symbols for architecture i386:
  "_OBJC_CLASS_$_FMDatabase", referenced from:
      objc-class-ref in AppDelegate.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Is it because iam using a 64bit system?
Just were looking for another version of FMDB but could only find the one on gitHub FMDB repository

Make sure FMDataBase.m is in your compile sources in the ‘Build Phases’ section
