Hard time compiling tess-two for android

Question

I'm trying to build eyes-two from the tess-two project using android studio. I did the ndk-build android ... ant release stuff for tess-two and eyes-two, imported eyes-two, configured ndk.dir path and all, but, while build I get the following error message:

allheaders.h: No such file or directory

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':tesstwo:compileReleaseNdk'.

You should build it using the instructions from here. https://github.com/rmtheis/tess-two/tree/master I had to slightly modify the instructions. To build the latest tess-two code, run the following commands in the terminal: git clone git://github.com/rmtheis/tess-two tess cd tess cd tess-two ndk-build android update project --path . --target 13 To build eyes-two, additionally run the following: cd .. cd eyes-two ndk-build android update project --path . --target 13 from there I opened android studio, File->import Sample and imported the Hello jni sample. after that was set up and compiling in android studio, I did File->New->Import Module pointed it at the tess-two directory selected all the defaults. at that point it gave me errors because of gradle issues. So I made this gradle file for the tess-two module:

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")
    }

}

Then it built successfully
