Loop initial declarations are only allowed in C99 or C11 mode

Issue

I have problem with building my android project with c++ file. It says that I must compile with C++11:

error: 'for' loop initial declarations are only allowed in C99 or C11 mode

And I know what this means, but I want to use c++11. And I have it included in gradle config:

android.ndk {
    moduleName = "native"

    stl = "gnustl_static"
    cppFlags += "-std=c++11"
    cppFlags += "-fexceptions"
    ldLibs.addAll(['android', 'log', 'OpenSLES'])
}

For what I searched, everyone has it same and it works. Does anybody know what is the problem?

Solution

Problem solved, it must be

CFlags.add("-std=c11")
