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 for building on POSIX
   compliant systems.
 * a Makefile.msc and sqlite3.rc for building with Microsoft Visual C++ on
   Windows.

SUMMARY OF HOW TO BUILD
=======================

  Unix:      ./configure; make
  Windows:   nmake /f Makefile.msc

................................................................................
  $ 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


BUILDING WITH MICROSOFT VISUAL C++
==================================

To compile for Windows using Microsoft Visual C++:

................................................................................

Using Microsoft Visual C++ 2013 (or later) is required.  When using the
above, something like the following macro will need to be added to the
NMAKE command line as well:

  "NSDKLIBPATH=%WindowsSdkDir%\..\8.1\lib\winv6.3\um\x86"

Building for UAP 10.0
---------------------

  FOR_WINRT=1 FOR_UAP=1

Using Microsoft Visual C++ 2015 (or later) is required.  When using the
above, something like the following macros will need to be added to the
NMAKE command line as well:

  "NSDKLIBPATH=%WindowsSdkDir%\..\10\lib\10.0.10586.0\um\x86"
  "PSDKLIBPATH=%WindowsSdkDir%\..\10\lib\10.0.10586.0\um\x86"

This package contains:

 * the SQLite library amalgamation source code file: sqlite3.c

 * the sqlite3.h and sqlite3ext.h header files that define the C-language
   interface to the sqlite3.c library file
 * the shell.c file used to build the sqlite3 command-line shell program
 * autoconf/automake installation infrastucture for building on POSIX
   compliant systems
 * a Makefile.msc and sqlite3.rc for building with Microsoft Visual C++ on
   Windows

SUMMARY OF HOW TO BUILD
=======================

  Unix:      ./configure; make
  Windows:   nmake /f Makefile.msc

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

to produce a smaller installation footprint.

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

  $ CFLAGS="-Os -DSQLITE_THREADSAFE=0" ./configure

/*
** The program does some simple static analysis of the sqlite3.c source
** file looking for mistakes.
**
** Usage:
**
**      ./srcck1 sqlite3.c
**
** This program looks for instances of assert(), ALWAYS(), NEVER() or
** testcase() that contain side-effects and reports errors if any such
** instances are found.
**
** The aim of this utility is to prevent recurrences of errors such
** as the one fixed at:
**
**   https://www.sqlite.org/src/info/a2952231ac7abe16
**
** Note that another similar error was found by this utility when it was
** first written.  That other error was fixed by the same check-in that
** committed the first version of this utility program.
