-lm is not needed and -lstdc++ is automatically added by g++. So
 remove that libraries from your command line. And be sure you use g++
 for compiling and linking C++ programs.

It the problem persists, reduce your program to a minimal test case
that reproduces the problem and post it here, plus the commands and
tool versions you are using.
