This morning I forked and checked out (again) Unreal Engine source code branch 4.5
Trying to compile running ./GenerateProjectFiles.sh I hit a silent fail.
I tried to freshly check out the source code many times. Nothing changed.
After fixing some missing dependencies I found out by looking at Engine/Build/BatchFiles/Linux/BuildThirdParty.log that rm couldn’t delete some build files. I solved giving the script sudo privileges.
Right now I am at this point
keru@keru-G73 ~/Documenti/gitDocuments/UnrealEngine/UnrealEngine $ sudo OAUTH_TOKEN=$TokenHere ./GenerateProjectFiles.sh
[sudo] password for keru:
Github build
Checking / downloading the latest archives
Asset Optional.zip up to date
Asset Required_1of2.zip up to date
Asset Required_2of2.zip up to date
All assets are up to date, not unpacking zip files again.
Building ThirdParty libraries
==> BuildLND
keru@keru-G73 ~/Documenti/gitDocuments/UnrealEngine/UnrealEngine $
Still no makefile is generated.
Looking at Engine/Build/BatchFiles/Linux/BuildThirdParty.log I can’t understand where the problem is.

Can someone help me to understand where my problem is?
What does it mean *** No rule to generate the object "/usr/lib/x86_64-linux-gnu/libGL.so", needed for "gtk2sdltest". Stopped.?
File /usr/lib/x86_64-linux-gnu/libGL.so already exists!
Also Engine/Source/ThirdParty/LinuxNativeDialogs/UELinuxNativeDialogs/build/CMakeFiles/CMakeError.log contains nothing interesting
Which other log files may contain something useful?
Oh… I almost forgot. I’m compiling on Linux Mint 17 Qiana, Cinnamon DE (Ubuntu trusty based system)
