Petros, FYI. gcc also has several different switches for object ouput:
eg. "gcc -c -static ..."
It might help to investigate these options during steps to compile sqlite.c
and your main program to avoid dynamic/static symbol conflicts.

Thank you Arjen and Simon for your answers, really helpful!
While there was progress by following the two commands noted in Arjen’s answer
and creating the libsqlite.a file, I stumbled upon the following errors:
[LD] astdb2sqlite3.o db1-ast/libdb1.a -> astdb2sqlite3

If you use the amalgamated source, there is only one file to be compiled. That
can be as simple as:
gcc -c sqlite3.c
ar r libsqlite3.a sqlite3.o
Any further dependencies are up to the linker. No need to worry about that.

Greetings dears!
While I am trying to build a static library of another tool which is dependent
to sqlite, I need to use an sqlite3 static library as well. Still, in my Centos
7.4 system, I cannot find one. The error is shown below:
/bin/ld: cannot find -lsqlite3
collect2: error: ld returned 1
I too am interested in this answer, I still have to start using fts5.
What would be interesting is to see the `EXPLAIN QUERY PLAN [query]` for
each of your queries, so as to see what causes the slowness.

Hello,
I observed the following behavior when using the wal_checkpoint PRAGMA
in TRUNCATE mode:
SQLite version 3.22.0 2018-01-22 18:45:57
Enter ".help" for usage hints.
Connected to a transient in-memory database.
Use ".open FILENAME" to reopen on a persistent database.

I ran a test and I can still find "database is locked" even if I use
busy_handler(threadsafe=2, 2 connections).
When thread 1 executing a writing transaction, thread 2 runs the code below
at the same time:
sqlite3_exec("BEGIN")
//SELECT
sqlite3_prepare_v2("SELECT * FROM t1;");
sqlite3_step;
