Cc1Plus: Error: Unrecognized Command Line Option "-Std=C++11" with G++

cc1plus: error: unrecognized command line option -std=c++11 with g++

Seeing from your G++ version, you need to update it badly. C++11 has only been available since G++ 4.3. The most recent version is 4.7.

In versions pre-G++ 4.7, you'll have to use -std=c++0x, for more recent versions you can use -std=c++11.

gcc 4.8.2 cc1plus: error: unrecognized command line option -std=gnu++11

I solved the problem.

The problem was the $PATH variables for me and other users.

Now, other users have an alias for g++ to the newer version, but their $PATH omits the actual location.

Make works based on their $PATH variable, so to fix it, I just had to make sure their path had the same location as mine.

unrecognized command line option ‘-std=c++11’

GCC 4.6 series is rather old (2011-2012). It was first released when C++11 was still called C++0x, so it supports -std=c++0x switch rather than std=c++11. Its support of C++11 is rather incomplete, so more modern code which uses C++11 features heavily may or may not compile.

Your 4.4.7 version of gcc is too old to fully enable C++11 features.
You need to upgrade the compiler to a version superior to 4.6 ( at least ) or if it's possible for you, upgrade your distro (let's say RHEL 7) which includes a more recent compiler.

cc1plus: error: unrecognized command line option -std=c++11

That flag was not added until a later version of g++ (4.7) to get the gcc 4.4 compat (as much as was there) you need to use the -std=c++0x flag.

cc1plus: error: unrecognized command line option -std=c++0x

According to this:

[rescape@iZ231twjza6Z mxnet]$ make

g++ ...

You not use CXX variable in your Makefile, so just replace g++ with CXX in your Makefile. aliases works only when you enter commands in your shell, if you type g++ something.cpp bash execute /home/bin/g++ something.cpp, that's all, bash aliasing not help if external process (in our case make) execute g++
