As per my thread:
Linux - "package project" takes to website :( - C++ - Epic Developer Community Forums(&p=286009#post286009
Im running the 4. editor, and cannot get my project to compile, so cant even open my project. This is the error log:
The project could not be compiled. Would you like to open it in an IDE to edit source code?

Your question got thrown to moderation because huge log you pasted, i placed it in PasteBin and posted link. Please use PasteBin or file attachment next time 
Ok, ive tried using the commandline to see if theres anything there that is of use…
Hi there
This:
[31m[2015.05.06-06.11.51:999][ 0]LogCompile:Error: Remapping old metadata key ‘FriendlyName’ to new key ‘DisplayName’, please update the declaration.
Seems to be your problem.
What does this mean? And how do I fix this?
ok made a new clean project and heres the error im now getting. I get the same error on a blank clean c++ project too!

You are missing the receipt file. Make sure that you invoke BuildCookRun with -build parameter, since the receipt file may not be generated otherwise.
(When combined with -clean, this will recompile your binary).
There are a few problems in the logs posted here. First there’s some blueprint error that prevents cook from succeeding (this is not Linux-specifc):
[2015.05.11-16.16.07:396][ 0]LogInit:Display: LogBlueprint:Error: [compiler BP_CloudVolume] Error Could not find a function named “GetScalabilityQuality” in ‘BP_CloudVolume’.
Second, when you invoke BuildCookRun command of UAT, make sure that you pass -build. Passing both -build and -clean should be a safe bet.
awesome, looks like the -build command was what was missing
Now i can get in there and fix it up!
