[GitHub] [incubator-kvrocks] PragmaTwice commented on pull request #764: Add LTO/IPO compile support

PragmaTwice commented on PR #764:
URL: https://github.com/apache/incubator-kvrocks/pull/764#issuecomment-1202447302

   It seems GCC builds in linux work well but Clang builds fail in linking phase (https://github.com/apache/incubator-kvrocks/runs/7631095274?check_suite_focus=true). 
   
   I have not tried it manually but I guess it maybe due to ld is used, which cannot recognize `*.o` generated by clang with `-flto` enabled (it is actually llvm bytecode in LTO mode).
   
   Hence you can try to replace ld with lld while clang is used. I can help you to do that if you do not familiar with those stuff.
