*************************************************************************
|
|
**
|
|
** This source allows multiple SQLite extensions to be either: combined
|
|
** into a single runtime-loadable library; or built into the SQLite shell
|
|
** using a preprocessing convention set by src/shell.c.in (and shell.c).
|
|
**
|
|
** Presently, it combines the base64.c and base85.c extensions. However,
|
|
** it can be used as a template for other combinations.
|
|
**
|
|
** Example usages:
|
|
**
|
|
** - Build a runtime-loadable extension from SQLite checkout directory:
|
|
** *Nix, OSX: gcc -O2 -shared -I. -fPIC -o basexx.so ext/misc/basexx.c
|
|
** Win32: cl /Os -I. ext/misc/basexx.c -link -dll -out:basexx.dll
|
|
**
|
|
** - Incorporate as built-in in sqlite3 shell:
|
|
** *Nix, OSX with gcc on a like platform:
|
|
** export mop1=-DSQLITE_SHELL_EXTSRC=ext/misc/basexx.c
|
|
** export mop2=-DSQLITE_SHELL_EXTFUNCS=BASEXX
|
|
** make sqlite3 "OPTS=$mop1 $mop2"
|
|
** Win32 with Microsoft toolset on Windows:
|
|
** set mop1=-DSQLITE_SHELL_EXTSRC=ext/misc/basexx.c
|
|
** set mop2=-DSQLITE_SHELL_EXTFUNCS=BASEXX
|
|
** set mops="OPTS=%mop1% %mop2%"
|
|
** nmake -f Makefile.msc sqlite3.exe %mops%
