Hi @masahiko.
Unfortunately at the moment YB should be built by GCC-7 or GCC-5.5 only. GCC-8 is not supported yet.
You can try to install GCC-7 on your system and try to rebuild YB.
Regarding the failed ‘cassandra-cpp-driver’ I can suggest a workaround how to disable the component building (this library is not really used by YB core processes) - edit 3 files in the YB source tree. The details are here: Building source code on Manjaro 18 · Issue #1720 · yugabyte/yugabyte-db · GitHub
