Hi Pavel, I think that's the issue. The .def file was never included. I put the .def file in the sqlite's project folder and am getting linker errors when I compile. I probably didn't reference it properly, I'll report back in a few minutes with success or failure.
--- Igor --- In Sqlite project, check Properties | Linker | Advanced | Import Library. Make sure it's not empty (normally, you should see something like $(OutputDir)$(TargetName).lib in there). Linker produces an import library (a LIB file) as a side-effect or building a DLL (unless this is suppressed). Projects using the DLL need the import library to link to. Igor Tandetnik -- It is set to generate a .lib according to that setting, but from what Pavel said, it never does because the .def file is missing from the project. I've never heard of .def files before so this is a new issue for me. This is all quite exciting :) Thanks, Kurt -----Original Message----- From: sqlite-users-boun...@sqlite.org [mailto:sqlite-users-boun...@sqlite.org] On Behalf Of Pavel Ivanov Sent: Thursday, December 17, 2009 10:04 AM To: General Discussion of SQLite Database Subject: Re: [sqlite] Compiling SQLite as .lib increases project sizeandbuild time? > If I remove the dependency on sqlite from HouseKeeper, it gives linker > errors with unresolved symbols for sqlite3_* functions. Adding sqlite as > a dependency to HouseKeeper causes it to look for the sqlite.lib file. Make sure that .def file is included in you Sqlite project. When compiling project as dll, compiler generates stub .lib file anyway for linking with anybody who will need this dll. But if you don't include .def file and thus don't define any functions to export from dll, compiler doesn't generate .lib file and it can cause the error you see.
