Hrm,, unfortunately, it does use the SQLite library (www.sqlite.org). Is it possible to link the library in the binary or do something else ?
In any case, if it's not possible at all with your current knowledge, I'd like to know how it's done anyway for a pure FPC program :) > - do you use 1.0.x or 1.1.x (I did it with 1.1.x, but 1.0.x is capable of it too) > Free Pascal Compiler version 1.0.10 [2003/08/18] for i386 Copyright (c) 1993-2003 by Florian Klaempfl > > If there is, I will need a step-by-step instruction, as I've never done > > it before without the need for a different machine. > > Let's make the shopping list first: > > You'll need > - crossbinutils (from ftp see below) > - a FreeBSD set of units matching the one you already have for linux. > > Retrieving and installation > --------------------------- > > Crossbinutils linux->about 10 platforms are available from > ftp://ftp.freepascal.org/fpc/contrib/cross/linux If this package is really > to large (26M) because you are not on broadband, yell, and I'll isolate the > FreeBSD ones from this package. > > Besides this, you need two matching FPC versions, one for FreeBSD one for > Linux.
