ubuntu 16.04 + UE4.19 + Clion2017.3,Failed to open selected source code accessor 'Clion'

[evehal]

and there is no Clion plugin setting in Project setting,and mono installed

Theres an issue where UE isn't telling UBT to build the right files ... something was removed during the merge. I've contacted Epic :)

after 4.19 release,i tried again:
Cannot get compiler information:
Compiler exited with error code 1: /usr/bin/c++ -xc++ -DACTORPICKERMODE_API= -

So bearer of bad news, 4.19 lacks a fix to let the plugin function correctly. It’s still working through engineering ... patch hopefully

You see this error because CMakeLists.txt does not tell anymore that you want to use clang. Editing the CMakeLists.txt in the root folder of your project directory you can add set(CMAKE_CXX_COMPILER /usr/bin/clang++) or whatever path your clang++ is installed on.
I've committed a change that should fix this issue on linux at least in the UE4 repository.
