◆ XAPIAN_AT_LEAST

#define XAPIAN_AT_LEAST	(	A,
		B,
		C )

Value:

 (XAPIAN_MAJOR_VERSION > (A) || \
 (XAPIAN_MAJOR_VERSION == (A) && \
 (XAPIAN_MINOR_VERSION > (B) || \
 (XAPIAN_MINOR_VERSION == (B) && XAPIAN_REVISION >= (C)))))

XAPIAN_AT_LEAST(A,B,C) checks for xapian-core >= A.B.C - use like so:

#if XAPIAN_AT_LEAST(1,4,2)
/* Code needing features needing Xapian >= 1.4.2. */
#endif

XAPIAN_AT_LEAST was added in Xapian 1.4.2. This was released 2016-12-26 so is now a reasonable hard requirement.

If you really want to support older versions beware that a check like:

#if defined XAPIAN_AT_LEAST && XAPIAN_AT_LEAST(1,4,12)

works with newer Xapian but fails to compile if the macro is not defined:

error: missing binary operator before token ‘(’

In this situation we recommend copying the definition of XAPIAN_AT_LEAST into your code and wrapping it in #ifndef XAPIAN_AT_LEAST ... #endif so you can use it unconditionally.

Since: Xapian 1.4.2.

◆ XAPIAN_MAJOR_VERSION

#define XAPIAN_MAJOR_VERSION 1

The major component of the Xapian version.

E.g. for Xapian 1.0.14 this would be: 1

◆ XAPIAN_MINOR_VERSION

#define XAPIAN_MINOR_VERSION 4

The minor component of the Xapian version.

E.g. for Xapian 1.0.14 this would be: 0

◆ XAPIAN_REVISION

#define XAPIAN_REVISION 31

The revision component of the Xapian version.
