Most of these are "source" files in the sense that they are stored in the configuration management system and are maintained directly. But 6 of the core C files are generated automatically using scripts or auxiliary programs during the compilation process. Of the 100 core files, 71 are C code and 29 are C header files.</p> <p>The standard makefiles for SQLite have a target for building an object we call the "amalgamation". The amalgamation is a single C code file, named "sqlite3.c", that contains all C code for the core SQLite library and the [FTS3] and [RTREE] extensions. This file contains about 149K lines of code (90K if you omit blank lines and comments) and is over 5.2 megabytes in size.</p> <p>The amalgamation contains everything you need to integrate SQLite into a larger project. Just copy the amalgamation into your source directory and compile it along with the other C code files in your project. (A [how to compile|more detailed discussion] of the compilation process is available.) You may also want to make use of the "sqlite3.h" header file that defines the programming API for SQLite. The sqlite3.h header file is available separately. The sqlite3.h file is also contained within the amalgamation, in the first few of thousand lines. So if you have a copy of sqlite3.c but cannot seem to locate sqlite3.h, you can always regenerate the sqlite3.h by copying and pasting from the amalgamation.</p> <p>In addition to making SQLite easier to incorporate into other projects, the amalgamation also makes it run faster. Many compilers are able to do additional optimizations on code when it is contained with in a single translation unit such as it |

In other words, this article provides ideas and insights, not turnkey solutions.</p> <h2>Amalgamation Versus Individual Source Files</h2> <p>SQLite is built from over one hundred of files of C code and script spread across multiple directories. The implementation of SQLite is pure ANSI-C, but many of the C-language source code files are either either generated or transformed by auxiliary C programs and AWK, SED, and TCL scripts prior to being incorporated into the finished SQLite library. Building the necessary C programs and transforming and/or creating the C-language source code for SQLite is a complex process.</p> |
