compilator Ubuntu

[Tomasz92]

What compilator should I install for the most new standards of C++ programming.
Now I have the new version g++ installed by command: sudo apt-get install g++,
but it doesn't work for example in the case of "auto" in the "lambda function"

[Dy7SLyTq]

a) its compiler not compilator
b) the repository for g++ on ubuntu gives you 4.6. you need to download the source for 4.8 and build that

Use g++-4.8 instead.

Thank you for your helps. But I'm starting person with Linux. So could you write mi how can I do it by the console? Thank you in advance.

[S G H]

sudo apt-get install g++-4.8

[Tomasz92]

I did it. But a got a communicate that didn't find packet g++-4.8.

[S G H]

Try with the following:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install g++-4.8

If you get an error with add-apt-repository, then do this before:

sudo apt-get install software-properties-common

I did such like you had written.

But when I try to compile I get:

my bad i didnt know that you could specify version number

[Dy7SLyTq]

well that looks like the 4.8 compiler. the errors looks like problems with your code

[S G H]

Well it's clear, you cannot assign a lambda to a function pointer.
A lambda can only be stored in an auto variable or as a function template parameter.
(Also as a class template parameter with declspec).

But every lambda, even with the same inputs and outputs, has a uniquely generated type.

About the rest, you're maybe using the wrong compiler?
I'm not sure how to force G++4.8 tho

[Dy7SLyTq]

I'm not sure how to force G++4.8 tho

absolute/relative paths? thats what i have to do with my build.

[Tomasz92]

Its not problem with code (its such seems to me), but with the compiler.
I can take here the code and you will can see it. But mayby Somebody have any idea what should I do?

[S G H]

Try to compile the following:

int main()
{
    [](){}();
    return 0;
}

If it works, the problem is in your code.
If it doesn't, the problem is in the compiler.

Thank you very much. Now everythink is OK ;)
