The sqlite command-line utility (sensibly) links against readline if it is present. Readline is licensed under the GPL.

Folk who wish to distribute their version of the sqlite utility under a license other than GPL may want to consider using the BSD libedit and read the thread around Jim Blandy's comments where the guile (lisp library) folk deal with a similar issue.

To include readline support on Mac OS X, do the following --

In latest version of readline source (4.3 when I did this), edit support/shobj-conf: Inside the darwin*|macosx* configuration... Replace: SHLIB_LIBS='-lSystem' With: SHLIB_LIBS='-lSystem -lcurses -lgcc'

  > ./configure
  > make
  > sudo make install

readline headers will get installed most likely under /usr/local/include

Then, in the SQLite source > ./configure

Edit the Makefile: # Compiler options needed for programs that use the readline() library. # READLINE_FLAGS = -DHAVE_READLINE=1 -I/usr/local/include/readline

# The library that programs using readline() must link against. # LIBREADLINE = -lreadline

> make > sudo make install

You now have a happy, readline capable SQLite.
