Android C++ Matlab NDK 오류 : :: rtNaN에 대한 정의되지 않은 참조

Question

Android Studio의 NDK에 Matlab 코드를 포함하려는 일부 문제가 있습니다. 하지만 오류가 발생했습니다

for (ii = 0; ii < i; ii++) { 
      yTemp[ii_data[ii] - 1] = rtNaN; <- error 
     } 

rtNaN의 정의가 소스 파일

I에

typedef double real_T; 
static real_T rtNaN; 

입니다 : 오류의

하나는이 라인에서 발생 내 build.gradle 파일에 다음을 추가했습니다. android { compileSdkVersion 23 //23.0.0 buildToolsVersion '23 .0.3 '이 오류가 발생한 이유

sourceSets.main{ 
    jni.srcDirs=[] 
    jniLibs.srcDir 'src/main/libs' 
} 

... 가}

내가 물어 봐도 내가 고칠 수있는 방법? 감사합니다

Answer 1

봅니다 앱 수준의 build.gradle이를 추가 : -

android{ 
defaultConfig{ 
ndk { 
      abiFilters "armeabi", "armeabi-v7a", "x86" 
     } 
    } 
} 

하면 앱 그대에게하는 .so 파일을 찾을 수 없기 때문에이 될 수 있습니다. 이 행은 올바르게 위치를 파악하는 데 도움이됩니다.

Answer 2

당신은 당신의 컴파일러 빌드 경로에 sensorgraph 라이브러리에 대한 경로를 포함해야합니다 :

-L 당신이 해결되지 않은 귀하의 문제가 해결 된 것입니다 수행 한 후

"경로// 스핑크스에" .
