b62f651…	stephan	18	** This file is NOT part of the Fossil executable. It is called from
b62f651…	stephan	19	** auto.def in the autosetup system.
b62f651…	stephan	20	**
b62f651…	stephan	21	** This file contains a test program used by ../configure with the
b62f651…	stephan	22	** the --disable-internal-sqlite option to determine whether or
b62f651…	stephan	23	** not the system SQLite library is sufficient to support Fossil.
b62f651…	stephan	24	**
b62f651…	stephan	25	** This must be compiled with -D MINIMUM_SQLITE_VERSION set in auto.def.
b62f651…	stephan	26	**
b62f651…	stephan	27	** It is preferred to statically link Fossil with the sqlite3.c source
b62f651…	stephan	28	** file that is part of the source tree and not use any SQLite shared
b62f651…	stephan	29	** library that is included with the system. But some packagers do not
b62f651…	stephan	30	** like to do this. Hence, we provide the option to link Fossil against
b62f651…	stephan	31	** the system SQLite shared library. But Fossil is very particular about
b62f651…	stephan	32	** the version and build options for SQLite. Unless a recent version of
b62f651…	stephan	33	** SQLite is available, and unless that SQLite is built using some
b62f651…	stephan	34	** non-default features, the system library won't meet the needs of
b62f651…	stephan	35	** Fossil. This program attempts to determine if the system library
b62f651…	stephan	36	** SQLite is sufficient for Fossil.
b62f651…	stephan	37	**
b62f651…	stephan	38	** Compile this program, linking it against the system SQLite library,
b62f651…	stephan	39	** and run it. If it returns with a zero exit code, then all is well.
b62f651…	stephan	40	** But if it returns a non-zero exit code, then the system SQLite library
b62f651…	stephan	41	** lacks some capability that Fossil uses. A message on stdout describes
b62f651…	stephan	42	** the missing feature.
