Building a DIY libsqlite3.so
(1) By anonymous on 2021-02-26 07:03:36 [link] [source]
I've got the source code (snapshot 202101022356) and build SQLite3 v.35. Nice! Now I want to build a new shared library (with and without debug information). Is there a procedure I should follow?

(First result from a web search for "build sqlite", by the way.)

That is the one I found. Unfortunately,I ran into a snag. shell.c:122:11: fatal error: readline/readline.h: No such file or directory The directory is not in snapshot. Oopsie?

The end of section 2 of that doc covers readline.

Thisd line Add -DHAVE_READLINE and the -lreadline and -lncurses libraries to get command-line editing support. That's exactly what I want. So I used this command:
gcc -Os -I. -DSQLITE_THREADSAFE=0 -DSQLITE_ENABLE_FTS4 -DSQLITE_ENABLE_FTS5 -DSQLITE_ENABLE_JSON1 -DSQLITE_ENABLE_RTREE -DSQLITE_ENABLE_EXPLAIN_COMMENTS -DHAVE_USLEEP -DHAVE_READLINE shell.c sqlite3.c -ldl -lreadline -lncurses -o sqlite3
Seems to me, that I checked all the boxes.

When you #define HAVE_READLINE, you should have the readline library. On Ubuntu, installing the package libreadline-dev suffices.

Thank you. I wasn't sure if that was the correct library because I ended up for this: /usr/bin/ld: /tmp/ccYRFinB.o: in function `fts5Bm25Function': sqlite3.c:(.text+0x3486f): undefined reference to `log' collect2: error: ld returned 1 exit status I am sorry that I am doing this step by step, but I want to be sure I didn't miss something that is important

-lm to the end of the build command.

Success!!! After a small victory dance I set down to check the version of the fresh compiled lib. You've probably guessed it — dramatic pause — v3.33.0. It's a déjà vu… (and a Freudian race condition of several anxieties.)
