How to use -std-c++11 in Eclipse C++

Question

I have this line written in my code

vector<GLfloat> cone1 { 0.0f, 2.4f, -11.0f, /*rotated*/30.0f, -1.5f, 0.0f, 0.0f };

But the errors comes up like in C++98, variable must be initialized by constructor not by {}

I have searched the solution that I should use -std-c++11, but I don't know how to add this in Eclipse?

Answer 1

You can do this in a few simple steps...

• Right-click on the the project and select "Properties"
• Navigate to C/C++ Build -> Settings
• Select the Tool Settings tab.
• Navigate to GCC C++ Compiler -> Miscellaneous
• In the option setting labeled Other Flags add -std=c++11

Now rebuild your project.

_{Note: this assumes you did not create your project to use GNU Autotools or a makefile.}
