1This is the SQLite extension for Tcl using the Tcl Extension 2Architecture (TEA). For additional information on SQLite see 3 4 http://www.sqlite.org/ 5 6 7UNIX BUILD 8========== 9 10Building under most UNIX systems is easy, just run the configure script 11and then run make. For more information about the build process, see 12the tcl/unix/README file in the Tcl src dist. The following minimal 13example will install the extension in the /opt/tcl directory. 14 15 $ cd sqlite-*-tea 16 $ ./configure --prefix=/opt/tcl 17 $ make 18 $ make install 19 20WINDOWS BUILD 21============= 22 23The recommended method to build extensions under windows is to use the 24Msys + Mingw build process. This provides a Unix-style build while 25generating native Windows binaries. Using the Msys + Mingw build tools 26means that you can use the same configure script as per the Unix build 27to create a Makefile. See the tcl/win/README file for the URL of 28the Msys + Mingw download. 29 30If you have VC++ then you may wish to use the files in the win 31subdirectory and build the extension using just VC++. These files have 32been designed to be as generic as possible but will require some 33additional maintenance by the project developer to synchronise with 34the TEA configure.in and Makefile.in files. Instructions for using the 35VC++ makefile are written in the first part of the Makefile.vc 36file. 37 38TCL SPECIFIC CHANGES 39==================== 40 41The version of SQLite provided by Tcl contains a number of additional 42enhancements and bug-fixes, in the process of being provided back to 43the SQLite developers. 44 45 * Enable SQLite Tcl binding to handle files from a Tcl VFS. 46 * Maximum path length enhanced from 260 to 4096 bytes for win32/cygwin 47 * Maximum path length enhanced from 512 to 4096 bytes for other platforms 48 * Maximum default page length enhanced from 8192 to 32768 49 * Maximum Number Of Attached Databases enhanced from 10 to 62 50 * VFS filename truncation issues 51 <https://www.sqlite.org/src/info/c060923a54> 52 * Wrong filename handling in sqlite3_load_extension() for Cygwin 53 <http://sqlite.1065341.n5.nabble.com/Wrong-filename-handling-in-sqlite3-load-extension-for-Cygwin-td74049.html> 54 * pragma database_list returns win32 paths on Cygwin 55 <http://sqlite.1065341.n5.nabble.com/pragma-database-list-returns-win32-paths-on-Cygwin-td74163.html> 56 * ISO time leap second 57 <http://sqlite.1065341.n5.nabble.com/ISO-time-leap-second-td77004.html> 58 * update to Unicode 12.1 for FTS3/4/5 tokenizer 59 * Extend memory interfaces from using "int" to "size_t". 60
