Below code can be compiled with windows clang but not ndk clang:
/////////////////////////////////////
typedef struct _AType* AType;
template<typename T>
struct Test
{
T& operator[](size_t index)
{
return this->val[index];
}
// need to comment off below otherwise ambiguous operator[] error is reported in ndk
operator AType() const
{
return this->atype;
}
operator T*()
{
return this->val;
}
AType atype;
T val[10];
};
Test<int> t;
t[0]; // ambiguous operator[] error in ndk
Enviroment:
windows: win10 + vscode 1.93.1 + cmake 3.29.2 + clang 18.1.8
android: win10 + android studio 2024.1.1 Patch 1 + cmake 3.30.3 + ndk 27.1.12297006 (clang 18.0.2)
Error log in ndk:
