# To build a single huge source file holding all of SQLite (or at
|
|
# least the core components - the test harness, shell, and TCL
|
|
# interface are omitted.) first do
|
|
#
|
|
# make target_source
|
|
#
|
|
# The make target above moves all of the source code files into
|
|
# a subdirectory named "tsrc". (This script expects to find the files
|
|
# there and will not work if they are not found.) There are a few
|
|
# generated C code files that are also added to the tsrc directory.
|
|
# For example, the "parse.c" and "parse.h" files to implement the
|
|
# the parser are derived from "parse.y" using lemon. And the
|
|
# "keywordhash.h" files is generated by a program named "mkkeywordhash".
|
|
#
|
|
# After the "tsrc" directory has been created and populated, run
|
|
# this script:
|

# tclsh mksqlite3c.tcl

|

|

# from in this file. The versioon number is needed to generate the header
|
|
# comment of the amalgamation.

|
|
** This file is an amalgamation of many separate C source files from SQLite
|
|
** version $VERSION. By combining all the individual C code files into this
|
|
** single large file, the entire code can be compiled as a single translation
|
|
** unit. This allows many compilers to do optimizations that would not be
|
|
** possible if the files were compiled separately. Performance improvements
|
|
** of 5% or more are commonly seen when SQLite is compiled as a single
|
|
** translation unit.
|
|
**
|
|
** This file is all you need to compile SQLite. To use SQLite in other
|
|
** programs, you need this file and the "sqlite3.h" header file that defines
|
|
** the programming interface to the SQLite library. (If you do not have
|
|
** the "sqlite3.h" header file at hand, you will find a copy embedded within
|
|
** the text of this file. Search for "Begin file sqlite3.h" to find the start
|
|
** of the embedded sqlite3.h header file.) Additional code files may be needed
|
|
** if you want a wrapper to interface SQLite with your choice of programming
|
|
** language. The code for the "sqlite3" command-line shell is also in a
|
|
** separate file. This file contains only code for the core SQLite library.
