Is this still the way to get SSL working on Android: http://doc.qt.io/qt-5/opensslsupport.html

SGaist

What version of the NDK, SDK, JDK are you using ?

vvvvv

@SGaist
I am using NDK android-ndk-r16b
The SDK is for API-27

java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

The strange thing is that it seems from the trace that the right include path are there???

vvvvv

This post is deleted!

vvvvv

these is the result from a command to get the used include path

It complains about non existing include path, I will check these later...

vvvvv

Some progress.....

I have noticed a difference between NDK16b and e.g. NDK12b

In the later android NDK distributions header files seem te be located in de sysroot directory.
https://developer.android.com/ndk/guides/standalone_toolchain.html

Building using the instructions http://doc.qt.io/qt-5/opensslsupport.html is working for the older NDK not for the newer. I will have to see if I can fix the Setenv_android.sh script to make it work for the newer NDK's too.

SGaist

Android has a tendency to break compatibility from one release of the NDK to the other.

You can find in the Android Getting Started of Qt's documentation the recommended versions of these dependencies.

vvvvv

Thank you ! I will if it works with the recommended version.

ekkescorner

@vvvvv you should use NDK r10e
perhaps this can help you: https://github.com/ekke/android-openssl-qt

vvvvv

@ekkescorner
It seem to be working now. I have used the NDK10e and SDK version21
Thank you for all,

cheers

ekkescorner

@vvvvv great to hear
