Error: non-aggregate type 'vector<int>' cannot be initialized with an initializer list

Question

I am a beginner in c++ and every time I run vector<int> nums = {2, 5, 3, 7, 1}; it gives me the Error: non-arregrate type vector cannot be initialized with initializer list.

Can you tell me why?

Thanks,

Most likely you need to turn on C++11 or higher. – Nerty

Can you tell me how to turn it on on a mac? – Ium

What compiler are you using and how are you compiling? – Nerty

I am using gcc on the compiler – Ium

@ian just pass -std=c++11. – Odontograph

it said command not found. – Ium

You need to pass it as an option to the compiler, e.g. g++ -std=c++11 prog.cpp. – Odontograph

Answer 1

Use g++ -std=c++11 <filename> when compiling.

Answer 2

Using Druhv Sehgal's answer above, this worked for me on mac

If command not found: gcc++ try

clang++ -std=c++11 <filename>

Where can I read about -std flag? I read cs.cmu.edu/~cburch/211-sp96/gnu_devel/gpp.html , but didn't found that option. – Sung

I found this gcc.gnu.org/onlinedocs/gcc/C-Dialect-Options.html, which has some options. I've only ever used c++11 so I'm not expert. This looks good too gcc.gnu.org/projects/cxx-status.html – Castaneda

Answer 3

If you are using VS code, then go to settings.json, Add "-std=c++17", "-stdlib=libc++" in the args array.
