Well, it's apparently just that your toolchain isn't using binutils consistently; usually LLVM's tools get installed as 'llvm-ar' and 'llvm-ranlib', or they don't get installed into the default PATH. You may try to reinstall binutils or create appropriate symlinks along PATH (such that 'ar' and 'ranlib' originate from them), but I have no idea whether that's at all related to your main problem. If 'ar' etc. fail but that error isn't catched that's of course a bug. -leif P.S.: Downgrading GCC of course (in this case at least) also downgrades libstdc++ (to 6.0.21), so programs and libraries built against the newer one are borked. If the newer libstdc++ didn't get removed, it's probably just a matter of symlinking libstdc++.so.6 back to the more recent one, presumably libstdc++.so.6.0.22 (from GCC 6.1). -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
