What do I need to set to make eclipse/cdt understand the for loop syntax below:

std::vector<int> intVector = {1,2,3,4};
for (int i : intVector) {
      printf("%d\n",i);
}


At the moment I get a yellow undelinging from 'for' to the ending '}'. "Syntax error" it what eclipse tells me.

Regards
Asmund

Does this compile with gcc/g++ command-line?

You for loop looks like a java syntax, not C/C++

This is C++11.

search for C++11 on wikipedia.org. (I was not allowed include a link)

On the page search for "Range-based for-loop".

To compile with g++:

g++ -std=c++0x

Oh. I'm not familiar with the current support fo C++11 in CDT. Hopefully someone else can answer. Sorry.

The bug report had a link to bug "Range-based for (bug 327223)". Fix was included in CDT 8.0 and I was running 7.0. Thank you!

I upgraded to Eclipse Indigo and have no problems now.

You will get a beer if we meet!
