Installing on Linux Mint 18, clang Errors, -Werror, -Wall, "shifting a negative signed value is undefined"

Trying to install UE4 on Linux Mint 18 Cinnamon Edition. For reference, Mint 18 is based on Ubuntu 16.04 LTS.
I am following this:

./Setup.sh fails on first attempt

$ ./Setup.sh Registering git hooks... (this will override existing ones!) Github build Checking / downloading the latest archives Checking dependencies (excluding Win32, Win64, Mac, HTML5, Android)... Received 1/1 files (0.6/0.6mb; 0.09mb/s; 100%)... Result: 0 Fixing inconsistent case in filenames. Building ThirdParty libraries If you don't see SUCCESS message in the end, then building did not finish properly. In that case, take a look into /home/a/UnrealEngine/Engine/Build/BatchFiles/Linux/BuildThirdParty.log for details. You run Ubuntu or its fork. All dependencies have been already prebuilt. ==> BuildHLSLCC

this is the contents of the “BuildThirdParty.log” file referenced in the terminal output:

so i installed clang (apt-get install clang), and ./Setup.sh succeeded. And then “make” failed.

Apparently there is a problem with clang. I tried downgrading clang (“apt-get remove clang” and then “apt-get install clang-3.6” and “apt-get install clang+±3.6”), but I got the exact same errors I started with before I entered “apt-get install clang”, with ./Setup.sh.

This problem is referenced here:

And I have asked questions on those posts. They recommend either downgrading clang (doesn’t work for me, as I already explained, it just gives the original problem), or adding lines to a file, but I think the file was changed since that post, because it seems I would be interrupting “functions” (forgive me if I got the term wrong) by adding those lines after line 343 as recommended. I mean line 343 is an if statement, 344 is a bracket, and then line 348 is an “else if” statement. And the lines recommended to be added are a seemingly unrelated if statement.

The file recommended to be edited is called LinuxToolChain.cs. The text of that file is copied below:

I have deleted “-Werror” from line 285.

And I have also installed libjpeg-dev, on the advice of this post:

Note: also “sudo apt-get install mono-gmcs” returns the error:

The following packages have unmet dependencies: mono-gmcs : Depends: mono-mcs (= 3.12.1-0xamarin1) but 4.6.2.7-0xamarin3 is to be installed E: Unable to correct problems, you have held broken packages.

I have mono-mcs installed, and mono-complete installed, though.

Also, “sudo apt-get install fglrx” returned a package not found error. So I installed “fglrx-pxpress” instead

By now, i have followed the instructions on the tutorial specifically for Linux Mint.

I run “make ./SlateViewer” and it returns:

This returns basically all the same errors I got before without following the instructions to Linux Mint, and just running make in the Unreal directory. Stuff about “shifting a negative signed value is undefined”.

And of course “./SlateViewer” returns a no such file error.

=== Update ===

new output of “make ./SlateViewer”

I don’t know why the output is different, or what I did, yet, but I will investigate very soon.

“./SlateViewer” still returns a "no such file or directory error though.

“make” is also still erroring:

Okay, I am changing directories to Engine/Binaries/Linux (even though there’s no mention of that on the tutorial on wiki in the section about installing slateviewer for linux mint), and entering ./SlateViewer, and I get the following error:

./SlateViewer: error while loading shared libraries: libLND.so: cannot open shared object file: No such file or directory

Okay, I left a comment yesterday, but it’s not showing up today. So I’ll re-write what didn’t show up for some reason.

I figured out that because I had also, a long time ago, attempted to use a different method (from Linux Mint - Community), I had the wrong GIT repos, and even though I was following A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums during this situation, my GIT repose were incorrect, and I was using version 4.7 – not 4.13.

So, all this stuff can be considered resolved for me. I don’t want to delete this post though incase anyone else runs into the same problems.

Deleting the contents of the UnrealDirectory and starting over got me past all these issues.
