g++ is not recognizing the option '-stdlib=libc++'

nlpguyz commented 5 years ago

I am using the command "python3 setup.py install" to compile the c++ code but got the error that "-stdlib=libc++" is not recognized. My environment is the following:

Ubuntu 16.04 g++ 5.4 python 3.5

If I manually remove "-stdlib=libc++" from setup.py and camera.cpp, compilation went through but I got a linker error in libusb-1.0.a:

Anyone fixed the issue? Thanks!
