android - NDK unable to deal with #include with relative paths? -


i'm writing adroid app c++ code behind ui using eclipse + ndk (r8d). have code thought fool proof compiler gives me weird errors "invalid arguments" without specifics. here c++ code looks like:

#include <jni.h> #include <string> using namespace std; #include "../../evaluator.engine/evaluator.engine.h"  evaluator evaluator;  extern "c" {     jniexport jstring jnicall java_haskellevaluator_android_mainactivity_evaluatenative(jnienv *env, jobject, jstring jinput)     {         ...         string sinput(l"hello world");         string sresult = evaluator.evaluate(sinput);         jstring jresult = env->newstringutf(sresult.data());         return jresult;     } }

evaluator.engine.h nothing fancy, declaration of class evaluator.

#include <string> using namespace std;  class evaluator { public:     string evaluate(string input); };

however, compiler complains:

invalid arguments ' candidates are: ? evaluate(?) '

as if string not defined. if put copy of header file under same folder, error goes away. windows box. have tried using \ , escaped \\ path separators , didn't work.

does sound ndk (or whatever preprocessor uses) bug? don't want move header file because it'll shared other projects. hate keep 2 copies of same file.

any ideas? thanks.

sorry don't have windows os, i've tried code on macos, doesn't work because of:

string sinput(l"hello world");

saying wchar_t cannot put on std::string. possible same problem ?
