Errors with compiling sqlite database with c++ builder 5

I'm having trouble trying to compile sqlite database with C++Builder 5 code.

I downloaded sqlite-amalgamation, and added all the files to the project:

shell.c
sqlite3.c
sqlite3.h
sqlite3ext.h

Then I included sqlite3.h in the MainForm where the database will be used.

First I thought it was my code which had problems, but after testing it with a simple Form with a DBGrid to show data inside the database, I get these errors:

What is the problem?

I followed Internet tutorials on how to add sqlite, but they don't work.

If it's not possible to use sqlite with C++Builder 5, is there another embedded database that is compatible with it?

I heard I can use a CSV file as a database, can I do that? If so, how?

The file shell.c is for the command-line shell; you do not need it to access databases from your code.

The only files you need are sqlite3.c and sqlite3.h, and only the former actually needs to be compiled.
