Issue MESOS-5263: pivot_root is not available on ARM
When compile on ARM, it will through error. The current code logic in src/linux/fs.cpp is: {code} #ifdef __NR_pivot_root int ret = ::syscall(__NR_pivot_root, newRoot.c_str(), putOld.c_str()); #elif __x86_64__ // A workaround for systems that have an old glib but have a new // kernel. The magic number '155' is the syscall number for // 'pivot_root' on the x86_64 architecture, see // arch/x86/syscalls/syscall_64.tbl int ret = ::syscall(155, newRoot.c_str(), putOld.c_str()); #elif __powerpc__ || __ppc__ || __powerpc64__ || __ppc64__ // A workaround for powerpc. The magic number '203' is the syscall // number for 'pivot_root' on the powerpc architecture, see // https://w3challs.com/syscalls/?arch=powerpc_64 int ret = ::syscall(203, newRoot.c_str(), putOld.c_str()); #else #error "pivot_root is not available" #endif {code} Possible sollution is to add `unistd.h` header
