connecting sqlite to C program - c

Question

[SOLVED]
All I had to do was open the sqlite3.c file inside my "project tree" like this and include sqlite3.h in the header.
I'm trying to connect my C program (using Code Blocks) to a database. I've already downloaded all the key files from the sqlite website like amalgamation zip file that comes with shell.c, sqlite3.c, sqlite3.h, and sqlite3ext.h.
I found this this tutorial on how to use libraries on code blocks. It's pretty simple, but then I realized that none of the files that came with amalgamation zip were .lib or .a. I know sqlite uses libraries, but all the files I listed above are source code files that access those libraries by themselves.
How to compile sqlite -> On their web site they have some good info: Everything is contained within a single code file, so it is easy to drop into the source tree of a larger C or C++ program. They meant the sqlite3.c file. But what did they mean by "dropping into the source tree"?
On the same page, there is a section Compiling The Command-Line Interface. I kind of got it the main points... I also found a sqlite shell tutorial here, so I downloaded the shell and now I can create/modify DBs. Although I feel like I'm pretty close to getting it to work on my C program, I still can't implement any DB from the source files or shell into my code.
Any thoughts?
#include <stdio.h> // printf
#include <sqlite3.h> // SQLite header (from /usr/include)
int main()
{
sqlite3 *db; // database connection
int rc; // return code
char *errmsg; // pointer to an error string
/*
* open SQLite database file test.db
* use ":memory:" to use an in-memory database
*/
rc = sqlite3_open(":memory:", &db);
if (rc != SQLITE_OK) {
printf("ERROR opening SQLite DB in memory: %s\n", sqlite3_errmsg(db));
goto out;
}
printf("opened SQLite handle successfully.\n");
/* use the database... */
out:
/*
* close SQLite database
*/
sqlite3_close(db);
printf("database closed.\n");
}
Also, on the Command Line Shell For SQLite you can find a detailed explanation on how to transfer existing data (created from outside the C program since I still can't connect the DB to my C program) to a .txt file. This is good to know and all, but not exactly what I want. I could make it work using a lot of fread, fprintfetc...but that's not quite as good as having a actual DB implemented into your program. For instance, if later I wanted to make my program.c into a program.exe I could do it with the DB embedded inside the program.exe.

Answer 1

The amalgation expects that you put all files of the amalgation in you project folder, that you add #include "sqlite3.h" in your sources that want to access sqlite and that you make sqlite3.c a member of your project.
Assuming a gcc command line compiler, you should do:
gcc main.c sqlite3.c -lpthread -o foo
No need for a library here, and never try to include sqlite3.c.
