it complains about missing symbol | ld.lld: error: undefined symbol: std::__atomic_futex_unsigned_base::_M_futex_notify_all(unsigned int*) this is from gcc-14. | (trixie_armhf-dchroot)bigeasy@amdahl:~/llvm$ readelf -aW /usr/lib/arm-linux-gnueabihf/libstdc++.so.6.0.33 |grep futex_notify_all | 001a0eb0 00037d16 R_ARM_JUMP_SLOT 000a1061 _ZNSt28__atomic_futex_unsigned_base19_M_futex_notify_allEPj@@GLIBCXX_3.4.21 | 893: 000a1061 14 FUNC GLOBAL DEFAULT 12 _ZNSt28__atomic_futex_unsigned_base19_M_futex_notify_allEPj@@GLIBCXX_3.4.21 but on armel | (trixie_armel-dchroot)bigeasy@amdahl:~/llvm$ readelf -aW /usr/lib/arm-linux-gnueabi/libstdc++.so.6.0.33 |grep futex_notify_all | (trixie_armel-dchroot)bigeasy@amdahl:~/llvm$ given that llvm asks for futex_notify_all means that the header file provides the function (as in defines ATOMIC_INT_LOCK_FREE). It appears that futex.cc gets compiled during the build of gcc-14 as per build log. So my guess is that it either does not get linked to the finall libstdc++.so or the symbol is not exported and so missing. > > Cheers, > > Emilio Sebastian
