rt-thread/components/external/SQLite-3.8.1/autoconf

This package contains:

* the SQLite library amalgamation (single file) source code distribution,
* the shell.c file used to build the sqlite3 shell too, and
* the sqlite3.h and sqlite3ext.h header files required to link programs
and sqlite extensions against the installed libary.
* autoconf/automake installation infrastucture.

The generic installation instructions for autoconf/automake are found
in the INSTALL file.

The following SQLite specific boolean options are supported:

--enable-readline use readline in shell tool [default=yes]
--enable-threadsafe build a thread-safe library [default=yes]
--enable-dynamic-extensions support loadable extensions [default=yes]

The default value for the CFLAGS variable (options passed to the C
compiler) includes debugging symbols in the build, resulting in larger
binaries than are necessary. Override it on the configure command
line like this:

$ CFLAGS="-Os" ./configure

to produce a smaller installation footprint.

Other SQLite compilation parameters can also be set using CFLAGS. For
example:

$ CFLAGS="-Os -DSQLITE_OMIT_TRIGGERS" ./configure
