1 This package contains:
2
3 * the SQLite library amalgamation source code file: sqlite3.c
4 * the sqlite3.h and sqlite3ext.h header files that define the C-language
5 interface to the sqlite3.c library file
6 * the shell.c file used to build the sqlite3 command-line shell program
7 * autoconf-like installation infrastucture for building on POSIX
8 compliant systems
9 * a Makefile.msc, sqlite3.rc, and Replace.cs for building with Microsoft
10 Visual C++ on Windows

12 WHY USE THIS PACKAGE?
13 =====================
14
15 The canonical make system for SQLite requires TCL as part of the build
16 process. Various TCL scripts are used to generate parts of the code and
17 TCL is used to run tests. But some people would prefer to build SQLite
18 using only generic tools and without having to install TCL. The purpose
19 of this package is to provide that capability.
20
21 This package contains a pre-build SQLite amalgamation file "sqlite3.c"
22 (and its associated header file "sqlite3.h"). Because the
23 amalgamation has been pre-built, no TCL is required for the code
24 generate (the configure script itself is written in TCL but it can use
25 the embedded copy of JimTCL).
26
27 REASONS TO USE THE CANONICAL BUILD SYSTEM RATHER THAN THIS PACKAGE
28 ==================================================================
29
30 * the canonical build system allows you to run tests to verify that
31 the build worked
32 * the canonical build system supports more compile-time options
33 * the canonical build system works for any arbitrary check-in to
34 the SQLite source tree

43 SUMMARY OF HOW TO BUILD USING THIS PACKAGE
44 ==========================================
45
46 Unix: ./configure; make
47 Windows: nmake /f Makefile.msc
48
49 BUILDING ON POSIX
50 =================
51
52 The configure script follows common conventions, making it easy
53 to use for anyone who has configured a software tree before.
54 It supports a number of build-time flags, the full list of which
55 can be seen by running:
56
57 ./configure --help
58
59 The default value for the CFLAGS variable (options passed to the C
60 compiler) includes debugging symbols in the build, resulting in larger
61 binaries than are necessary. Override it on the configure command
62 line like this:
63
64 $ CFLAGS="-Os" ./configure
65
66 to produce a smaller installation footprint.
67
68 Many SQLite compilation parameters can be defined by passing flags
69 to the configure script. Others may be passed on in the CFLAGS. For
70 example:
71
72 $ CFLAGS="-Os -DSQLITE_OMIT_DEPRECATED" ./configure
73
74
75 BUILDING WITH MICROSOFT VISUAL C++
76 ==================================
77
78 To compile for Windows using Microsoft Visual C++:
79
80 $ nmake /f Makefile.msc
81
82 Using Microsoft Visual C++ 2005 (or later) is recommended. Several Windows
83 platform variants may be built by adding additional macros to the NMAKE
84 command line.
85
86
87 Other preprocessor defines
88 --------------------------
89
90 Additionally, preprocessor defines may be specified by using the OPTS macro
91 on the NMAKE command line. However, not all possible preprocessor defines
92 may be specified in this manner as some require the amalgamation to be built
93 with them enabled (see http://sqlite.org/compile.html). For example, the
94 following will work:
95
96 "OPTS=-DSQLITE_ENABLE_STAT4=1 -DSQLITE_OMIT_JSON=1"
97
98 However, the following will not compile unless the amalgamation was built
99 with it enabled:
100
101 "OPTS=-DSQLITE_ENABLE_UPDATE_DELETE_LIMIT=1"
