Building 64-bit Windows SQLite DLL using C++Builder XE3 64-bit compiler

Posted by on in Blogs
SQLite database access is now supported using dbExpress in Delphi XE3 and C++Builder XE3.  On the SQLite download page you will find a zip file containing the source code for SQLite 3.x (as of this blog post the verison is  Also on the download page you will find pre-compiled Windows binaries for the SQLite command line shell application and the SQLite Win32 DLL. In order to use SQLite with Delphi XE3 and C++Builder XE3 64-bit applications, you'll need to build a 64-bit version of the DLL. You can use C++Builder XE3's 64-bit compiler to build the 64-bit Windows DLL from the source code.  On a 64-bit Windows system (I am using Windows 7), you can put the Win32 SQLite3.dll in the C:\Windows\SysWOW64 folder.  After building the 64-bit DLL version, place it in the C:\Windows\System32 folder.  On my Mac OS X computer, the libsqlite3.dylib is already included in the /usr/lib folder.

After unpacking the source zip file, the following is the batch file (that I got from our R&D team) that I used to build the 64-bit Windows SQLite3.dll (modify the source path to wherever you put the source code):

    set rootdir=^
    "C:\Users\embt\Desktop\Demos in progress\CppSQLiteBuildDLL\sqlite-amalgamation-3071502"
    -I %rootdir%\include\windows\crtl^
    -I %rootdir%\include\windows\sdk^
    -D "SQLITE_API=__declspec(dllexport)"^
    -D WIN64^
    -D NDEBUG^
    -D _WINDOWS^
    -D _USRDLL^
    -D NO_TCL^
    -D TEMP_STORE=1^
    sqlite3.c shell.c

A few notes about some of the bcc64 command line options used in the batch file:

  • -tWD = target Windows DLL

  • -L <value> = library file search path

  • -I <value> = include file search path

  • -D <name>=<value> = define a symbol name and optional value (used for conditional compilation)

For additional information about SQLite specific compilation options - go to  Please note that the SQLite3 Win32 DLL is built with using the SQLITE_ENABLE_COLUMN_METADATA define. The batch file above also sets this define. Also note that the libsqlite3.dylib that was included in my /usr/lib folder was not built with this option.

Have fun using SQLite3 with your Delphi and C++Builder XE3 applications for Windows (Win32 and Win64) and Mac OS X.  I am putting the finishing touches on a short video that shows how to build the 64-bit SQLite3.DLL and also how to build C++Builder XE3 FireMonkey SQLite based applications (including in-memory databases) for Windows and Mac.

    You can find our own 3.7.16 version of the SQlite3 external library, to be used in 64 bit mode, and compiled with the above line code (including FTS3/FTS4) to be downloaded from

    This is the version we use when our Open Source mORMot framework targets Win64, using Delphi XE2/XE3.

    Hope it helps.

    Thanks for the input, David!

    Can I build 64-bit object files in C++ Builder XE4 and link them directly into a 64-bit Delphi XE4 project, rather than having them be a separate DLL?
