The manual for the installation of CodeWorks for Android on Linux (found here [https://docs.unrealengine.com/latest/INT/Platforms/Android/GettingStarted/1/index.html]) is missing some steps.
First you have to ensure your /tmp/ directory to be executable. This can be done with the command:
mount -o remount,exec /tmp/
You also need the legacy libpng version 1.2. For Gentoo Linux the command is:
emerge libpng:1.2
This will solve some issues. It would be great to update the docs.
Please put this on the forums too. I hope what you did is appreciated and encourages others to do the same.
