Hi all. I'm trying to build a MacRuby 0.8 app with XCode. I want to interact with an exisitng Sqlite3 database. Since I don't want to package or mess with any Rubygem, I decided to look into existing Objective-C Sqlite wrappers. I've tried PLDatabase and fmdb, and failed with both. The code compiles and the application runs, but when calling a C function what accepts a va_arg argument list, my app receives a EXC_BAD_INSTRUCTION. Example: Objective-C function interface: - (FMResultSet *)executeQuery:(NSString*)sql, ... { Ruby code db.executeQuery "SELECT * FROM call" it receives the error on this C line inside the executeQuery function va_start(args, sql); Any hints? Do you recommend a simple way of interacting with a Sqlite3 app with macruby + xcode, without using any gems? Thank you Ruben
