Description

Before v0.14 this was valid

#if EXIV2_CHECK_VERSION(0,14,0)

In 0.14 this use of the macro is no longer valid.

Additional information:

Workaround: Add code like this to the application to define a EXIV2_TEST_VERSION macro which can be used in a preprocessor test with all versions of exiv2, instead of EXIV2_CHECK_VERSION:

#include <exiv2/types.hpp>
#ifdef EXIV2_VERSION

ifndef EXIV2_TEST_VERSION
define EXIV2_TEST_VERSION(major,minor,patch) \
( EXIV2_VERSION >= EXIV2_MAKE_VERSION(major,minor,patch) )
endif
#else
define EXIV2_TEST_VERSION(major,minor,patch) (false)
#endif
