how to fix "arm-linux-gnueabihf/lib/libstdc++.so: undefined reference to `clock_gettime@GLIBC_2.17'?

[kipade]

thanks for your reply. my link cmd is:
arm-linux-gnueabihf-g++ main.o -L ../arm_common/build/lib/ -larmcomm -pthread -lelf  -ldl -lrt



here, arm_common is my own lib for my use. because I use shm_xxx functions for shared memory,
so I have to link rt.
