Today, I would like to share with you the relevant knowledge points about how to solve the linux compilation and installation error report td=c++11. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article.

We are using the linux system to compile and install the prompt for unrecognized command line option "- std=c++11" unrecognized command line option "- std=c++11". The reason for this compilation error is not high enough in the Globe + gcc version.

Update gcc version the default is 4.4.7 version of gcc

Command View:

# gcc-v

Update method

1. Download the compressed package for compilation and installation

Wgettar-jxvfgcc-4.8.2.tar.bz2

2. Download the dependencies for compilation requirements

This magical script file will help us download, configure, and install dependent libraries, saving us a lot of time and energy.

Cdgcc-4.8.0./contrib/download_prerequisites

3. Create a folder
