--- Comment #3 from Matthias Klose <doko at gcc dot gnu.org> --- I found this snippet in one of the xapian headers. #ifdef __GNUC__ #if __GNUC__ < 3 || (__GNUC__ == 3 && __GNUC_MINOR__ == 0) #error Xapian no longer supports GCC < 3.1 #else #if !defined(__GXX_ABI_VERSION) || __GXX_ABI_VERSION != 1002 #error The C++ ABI version of compiler you are using does not match #error that of the compiler used to build the library. The versions #error must match or your program will not work correctly. #error The Xapian library was built with g++ 4.9.1 #endif my impression was that a value of 999999 means something like "unstable"/"newest". Assuming that there will be another version, which value should be chosen for that one?
