arm cross get error about paho.mqtt.cpp

Hi. Can you copy and paste the full output of the build? I can't tell from just this.
Also, have you considered upgrading the compiler? gcc4.9 is nearly 10years old.

Hi,this is error ,thanks

I tried to build a (native) gcc-4.9 for my system, but apparently the older gcc compilers can't be built by the latest versions?!?

As I recall, v4.9 had good C++11 coverage, so I thought it would be able to build the library. I think I was using v4.8 when I first wrote it.

Did it work with a newer compiler?
