Hello Xi Ruoyao,

  Now I met a issue when start process by systemd:

     profiling:/root/rpmbuild/BUILD/project/daemon/daemon.gcda:Cannot open
  
  I'am sure that the progress have root privilege. I also "chmod 777" this
directory(daemon). This directory have daemon.c daemon.o daemon.gcno files.
What else can I check?

Thanks!
