[Bug c++/64956] [5 Regression] __GXX_ABI_VERSION needs a proper definition for the 5.x releases
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64956 --- Comment #6 from Jason Merrill jason at gcc dot gnu.org --- (In reply to Matthias Klose from comment #3) #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 I would expect that Xapian built with -fabi-version=2 and -fabi-version=8 should be compatible; the only changes to the compiler ABI are mangling, which with a template library probably only leads to a bit of code bloat from duplicated functions with different names. I suppose there could be runtime issues if there are variables mangled differently, but that's less likely.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64956 --- 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 99 means something like unstable/newest. Assuming that there will be another version, which value should be chosen for that one?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64956 --- Comment #2 from Jakub Jelinek jakub at gcc dot gnu.org --- Well, -fabi-version=0 (which is the default now) has always behaved that way. The question is if we want to change that or not.
