Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- libsupc++.a (fundamental_type_info.o) (also included in libstdc++.a and libstdc++.so.6) should provide those symbols since r13-4722 if the target supports _Float{16,32,64,128} or __bf16. Are you sure you're linking against GCC 13+ libstdc++.a? On x86_64 I certainly see nm fundamental_type_info.o | grep ZTIDF 0000000000000000 V _ZTIDF128_ 0000000000000000 V _ZTIDF16_ 0000000000000000 V _ZTIDF16b 0000000000000000 V _ZTIDF32_ 0000000000000000 V _ZTIDF32x 0000000000000000 V _ZTIDF64_ 0000000000000000 V _ZTIDF64x
