# 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

|
|
# The amalgamated SQLite code will be written into sqlite3.c
|
|
#
|
|
|
|
# Begin by reading the "sqlite3.h" header file. Count the number of lines
|
|
# in this file and extract the version number. That information will be
|
|
# needed in order to generate the header of the amalgamation.
