Template in Android NDK

[ra...@cin.ufpe.br]

Hello there!

I'm trying to compile a library for Android that is in C++. It is implemented in .h and .hpp files. I included the folder that have all the files. I'm using Android Studio 3.0.1 and NDK r16b with Clang 5.0.300080 compiler. However, I'm having the following error with some functions:

error: use of undeclared identifier 'ExistChild'

It uses the ExistChild function in the KdTree class, which inherits the class BaseTree, which implements this function. 

class KdTree
: public StrategiesT::template StrategyBase
    <
        MetricT
        <
            VectorKernelT
            <
                BaseTree
                <
                    KdTreeCell< typename StrategiesT::CellData >
                >
            >
        >
    >
{
    ...
};

Since this code compiles in Visual Studio, I suspect that the problem may be that the Android C++ compiler does not support this kind of template specialization. I searched around and I couldn't find any information that confirms or denies this.

Does anybody encounter this problem before?

Best, Rafael!

Hi,

Maybe you need to set -std=c++14 ?

BR,

Hi Alex,

thanks for the suggestion, but I am still having the same error using c++14. Right now, I'm trying to compile this library for desktop platform using the same Clang compiler to rule out the possibility of incompatibility between this code and this specific compiler.

Best,

Rafael
