basic program to compile:

import etc.c.sqlite3 : sqlite3_open;

When compiling with DMD v2.066.1, I get this error:

test.o: In function `_Dmain':
test.d:(.text._Dmain+0x2f): undefined reference to `sqlite3_open'
collect2: ld returned 1 exit status

Any idea what I'm doing wrong? I'm on Ubuntu 12.04 64-bit, but I 
doubt that matters. I've tried a couple alternatives, but they 
didn't work either.

stumped. I get what the error means, but I don't understand why 
it's occurring.

Are you linking with libsqlite3.a?

For example:

$ dmd prog.d -L-lsqlite3

That worked, thanks. I didn't know you had to anything special to 
link with code in the standard library; is there documentation 
for this somewhere?

Also, is there a way I could make SQLite work with DUB rather 
than building manually? The command-line help and web page don't 
seem to mention this anywhere.

D doesn't have the whole implementation of SQLite. It is 
implemented as a library, and the sqlite3 module hooks up to 
library's functions. So, you should give your program the library 
ie. implementation of SQLite.
