Android Studio: ERROR: '__NDK_FPABI__' does not name a type

[Marcos Bontempo]

Hello,

I'm with the same error as these links to build the OpenCV Face Detection example for Android:

http://stackoverflow.com/questions/22106857/error-ndk-fpabi-does-not-name-a-type

http://stackoverflow.com/questions/23339489/error-ndk-fpabi-does-not-name-a-type-version-2

I'm sorry for asking the same question, but the answers wasn't clear to me. I understood that the error occurs because Android Studio is using the libraries from /usr/include instead of the libraries from the NDK. However, I don't how to correct. 

Here are my files:

Android.mk

    LOCAL_PATH := $(call my-dir)
    
    include $(CLEAR_VARS)
    
    include /home/marcos/Downloads/Eclipse_Android_OpenCV/OpenCV-android-sdk/sdk/native/jni/OpenCV.mk
    
    #OPENCV_CAMERA_MODULES:=off
    OPENCV_INSTALL_MODULES:=on
    #OPENCV_LIB_TYPE:=SHARED
    
    LOCAL_SRC_FILES  := DetectionBasedTracker_jni.cpp
    LOCAL_C_INCLUDES += $(LOCAL_PATH) 
    LOCAL_LDLIBS     += -llog -ldl
    LOCAL_SDK_VERSION := 23
    LOCAL_NDK_STL_VARIANT := gnustl_static
    
    LOCAL_MODULE     := detection_based_tracker
    
    include $(BUILD_SHARED_LIBRARY)



Application.mk

    APP_STL := gnustl_static
    APP_CPPFLAGS := -frtti -fexceptions
    APP_ABI := armeabi-v7a
    APP_PLATFORM := android-8



build.graddle

    apply plugin: 'com.android.application'
    
    android {
        compileSdkVersion 23
        buildToolsVersion "23.0.2"
    
        sourceSets.main {
            jniLibs.srcDir 'src/main/libs'
            jni.srcDirs = [] //disable automatic ndk-build call
        }
    
        defaultConfig {
            applicationId "org.opencv.samples.facedetect"
            minSdkVersion 8
            targetSdkVersion 23
    
            ndk {
                moduleName "detection_based_tracker"
            }
        }
    
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
            }
        }
    
        tasks.withType(JavaCompile) {
            compileTask -> compileTask.dependsOn ndkLibsToJar
        }
    
        task ndkLibsToJar(type: Zip, dependsOn: 'ndkBuild', description: 'Create a JAR of the native libs') {
            destinationDir new File(buildDir, 'libs')
            baseName 'ndk-libs'
            extension 'jar'
            from(new File(buildDir, 'libs')) { include '**/*.so' }
            into 'lib/'
        }
    
        task ndkBuild(type: Exec, description: 'Compile JNI source via NDK') {
            println('executing ndkBuild')
            commandLine "/home/marcos/Downloads/Eclipse_Android_OpenCV/android-ndk-r12b/ndk-build",
                    'NDK_PROJECT_PATH=build',
                    'APP_BUILD_SCRIPT=src/main/jni/Android.mk',
                    'NDK_APPLICATION_MK=src/main/jni/Application.mk'
        }
    }
    
    dependencies {
        compile project(':openCVLibrary2411')
    }



And here are the errors:

    Error:(856, 5) error: '__NDK_FPABI__' does not name a type
    Error:(36, 2) error: #error Bionic header ctype.h does not define either _U nor _CTYPE_U

    Error:(68, 47) error: '_CTYPE_N' was not declared in this scope



Does anybody know how to correct it? 

Any tip will be very helpful,

Thanks.

Actually, that's not the same bug. Looked similar at first glance though.

 

APP_PLATFORM := android-8

Obsolete. That platform isn't in r12b. Change that to 9 and it'll fix at least one class of issues if not all of them.

LOCAL_SDK_VERSION := 23

This is a no op, btw. LOCAL_SDK_VERSION means nothing in the NDK.
