Beginner questions / Re: Trouble including sqlite3 with a project
« Last post by algernon_77 on August 25, 2020, 04:25:52 pm »
Hi,

Yes, the dll includes everything, but so would your executable - all the code resides in sqlite3.c, which the compiler will transform in sqlite3.obj, which the linker will put together with you code and the resulting exe would be very much like the dll in size, even if you used just a function.

If every function from sqlite3.c would reside in a separate module (*.c file), and then you would compile all the .c files into .objs, you could make a static library from them and link against it every time you would like to use sqlite3. Then, if you would have used function "X", the linker would link just X.obj, and your exe wouldn't contain all the other unused procedures.

I just tried it, (with the above code from OP) and the resulting exe is about 730kb :)
If you want to give it a shot, don't forget to select "multithreaded lib" from proj. options->compiler->code gen.

Regards!

Thanks very much.  Just found that link too - thanks for putting it here.

I'll probably try the amalgamation file because it is simpler to deploy a single exe.
The program actually could end up smaller (in total) if only the used functions are
included because the dll by default must include everything I imagine.

I don't see any impediment in using the amalgamation file, I imagine Pelle would compile it with no fuss, but in all honesty, I haven't tried it personally.
It would just make your executable bigger, but nowadays, I don't see how that would be much of a problem :)

You can find an ODBC driver here: http://www.ch-werner.de/sqliteodbc/
I haven't tried this either :)

If you are going to distribute your application wouldn't it be easier to use the C source code amalgamation rather than the dll and lib?  As I read it (I'm just starting to learn sqlite3) you can just include one C source file and one .h file into your code base.  No need for the dll or lib.   

BTW Is there a windows ODBC driver for sqlite3 ?

Hello there!

You'll also need the import library for the program to compile and sqlite3.dll for your program to start.
Please see the links below, one is for the 64 bit version, the other is for x86 (32 bit).

x86:
https://drive.google.com/file/d/1IwSp5s9R3TfEcMQhKl2tJ75_GGe21ibq/view?usp=sharing

x64:
https://drive.google.com/file/d/1FpDV0_NeRtIHdcK2YzLwcDVihYPWrgki/view?usp=sharing

- for 64 bit: put sqlite3.lib from the 64bit archive in \PellesC\Lib\Win64
- for 32 bit: put sqlite3.lib from the 32bit archive in \PellesC\Lib\Win
- put sqlite3.h in \PellesC\Include\Win

On your project, #include <sqlite3.h> in the source and on "project options->linker->library and obj. files" add sqlite3.lib to the list.
Put sqlite3.dll in the project folder (the one form the 32bit archive for 32bit projects, the one from the 64bit archive for 64 bit projects).

Hope it helps (it works for me).
