为android编译tess-two时遇到的困难

Question

我正在尝试使用android Studio从tess-two项目中构建两只眼睛。我为tess-two和eyes-two做了ndk-build android...ant发布的东西，导入了eyes-two，配置了NDK.dir路径等等，但是，在构建时，我得到了以下错误消息：

allheaders.h: No such file or directory

FAILURE: Build failed with an exception.

* What went wrong:

您应该使用此处的说明构建它。https://github.com/rmtheis/tess-two/tree/master我不得不稍微修改一下说明。要构建最新的tess-two代码，在终端中运行以下命令:git clone git://github.com/rmtheis/tess-two tess cd tess cd tess-two ndk-build android update project--path。-target 13构建眼睛-两个，另外运行以下命令:cd。cd眼睛-两个NDK-构建android更新项目-路径。--target13从那里我打开了android studio，文件->Import Sample并导入了Hello jni示例。之后在android studio中进行了设置和编译，我做了文件->New->Import模块，将其指向tess-two目录，选择了所有的默认值。在这一点上，它给了我错误，因为分级问题。所以我为tess-two模块制作了这个分级文件：

apply plugin: 'com.android.model.library'

model {
    android {
        compileSdkVersion = 23
        buildToolsVersion = "23.0.0"

        defaultConfig.with {
            minSdkVersion.apiLevel = 15
            targetSdkVersion.apiLevel = 23
        }
    }


    compileOptions.with {
        sourceCompatibility=JavaVersion.VERSION_1_7
        targetCompatibility=JavaVersion.VERSION_1_7
    }

    android.buildTypes {
        release {
            minifyEnabled = false
            proguardFiles  += file('proguard-rules.txt')
        }
    }
    android.productFlavors {
        // for detailed abiFilter descriptions, refer to "Supported ABIs" @
        // https://developer.android.com/ndk/guides/abis.html#sa
        create("arm") {
            ndk.abiFilters += "armeabi"
        }
        create("arm7") {
            ndk.abiFilters += "armeabi-v7a"
        }
        create("arm8") {
            ndk.abiFilters += "arm64-v8a"
        }
        create("x86") {
            ndk.abiFilters += "x86"
        }
        create("x86-64") {
            ndk.abiFilters += "x86_64"
        }
        create("mips") {
            ndk.abiFilters += "mips"
        }
        create("mips-64") {
            ndk.abiFilters += "mips64"
        }
        // To include all cpu architectures, leaves abiFilters empty
        create("all")
    }

}

那么它就成功地构建了
