Bug#850831: ceph: FTBFS on some 32-bit architectures: undefined reference to `__atomic_load_8'
Source: ceph
Version: 10.2.5-5
Severity: normal
User: debian-68k@lists.debian.org
Usertags: m68k
Hi!
On at least m68k and powerpc, ceph fails to build from source because the
linker cannot resolve symbols for 64-bit atomics [1]:
/usr/include/c++/6/bits/atomic_base.h:396: undefined reference to `__atomic_load_8'
rocksdb/librocksdb.a(version_set.o): In function `std::__atomic_base<unsigned long long>::store(unsigned long long, std::memory_order)':
/usr/include/c++/6/bits/atomic_base.h:374: undefined reference to `__atomic_store_8'
/usr/include/c++/6/bits/atomic_base.h:374: undefined reference to `__atomic_store_8'
rocksdb/librocksdb.a(version_set.o): In function `std::__atomic_base<unsigned long long>::load(std::memory_order) const':
(...)
/usr/include/c++/6/bits/atomic_base.h:396: undefined reference to `__atomic_load_8'
rocksdb/librocksdb.a(rate_limiter.o): In function `std::__atomic_base<long long>::store(long long, std::memory_order)':
/usr/include/c++/6/bits/atomic_base.h:374: undefined reference to `__atomic_store_8'
rocksdb/librocksdb.a(rate_limiter.o): In function `std::__atomic_base<long long>::load(std::memory_order) const':
/usr/include/c++/6/bits/atomic_base.h:396: undefined reference to `__atomic_load_8'
collect2: error: ld returned 1 exit status
This is reminiscent to a similar issue recently fixed in src:limequite [2]. The
patch to resolve it linked -latomic with --as-needed which is a better solution
than the current approach which just hardwires -latomic on mips/mipsel.
Thanks,
Adrian
