To resolve this undefined references (__cxa_guard_acquire ) , add a library flag "-lstdc++" in your Makefile. It should work. It worked for me.

加上后工作正常。

在 gcc编译语句后添加-lstdc++即可。
如果出现其他未定义声明的情况:
undefined reference to `XXX‘
collect2: ld returned 1 exit status
同理添加-lxxx编译参数即可。
错误 undefined reference to __cxa_guard_acquire/release
