I'm including OpenSSL in my Android project using david-hoze/build-openssl-android: Builds openssl 1.1.0h with android ndk r17..
This is my setup: Android Studio 3.2 NDK version: 18.0.5002713
This is my app's build.gradle file:
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
def my_openssl_dir = getRootDir().toString() + "/build-openssl-android/openssl-lib"
android {
compileSdkVersion 27
defaultConfig {
applicationId "com.my-company.my-app"
minSdkVersion 21
targetSdkVersion 27
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
externalNativeBuild {
cmake {
cppFlags "-std=c++17 -frtti -fexceptions"
arguments '-DANDROID_STL=c++_shared'

}
}
}
buildTypes {

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
externalNativeBuild {
cmake {

}
}
sourceSets {
main {
jniLibs.srcDirs = [

}
}
}

This is my CMakeLists.txt file:

And I'm getting these errors while compiling:

Would appreciate your help.
