Using Lazarus and FPC and sqlite3conn unit, I can use the sqlite3.dll
on windows without problem.
However, when I try to convert my project to win 64, it just fail
without any warning.
I am using
FPC 3.1.1 Revision 63034
Lazarus 1.9.0
both are Win64
I download the win 64 bit version of sqlite3.dll from
https://www.sqlite.org/2018/sqlite-dll-win64-x64-3250200.zip
and place it in the same folder as my exe.
The project compiles without errors nor warning.
But when I run the exe, it just waits a few seconds and then quits
silently.
I tried debugging it and set breakpoints at all of the following in
sqlite3.inc
function TryInitializeSqlite(const LibraryName: UnicodeString): Integer;
function InitialiseSQLite:integer;
function InitializeSQLiteANSI(const LibraryName: AnsiString):integer;
function InitializeSQLite(const LibraryName: UnicodeString) :integer;
function InitialiseSQLite(const LibraryName: UnicodeString):integer;
and the following in SQLite3Conn:
class function TSQLite3ConnectionDef.DefaultLibraryName: string;
class function TSQLite3ConnectionDef.LoadedLibraryName: string;
class function TSQLite3ConnectionDef.LoadFunction: TLibraryLoadFunction;
However, the debugger did not stop at all at any of them.
What could possibly be the cause of the problem?
A simple test here with a SQLite3Connection works without problems.
Do you get an exception if the library is *not* located in the same
folder? In that case it loaded correctly and something else must be the
problem.

Sven
