ERROR: Platform Linux is not a valid platform to build. Check that the SDK is installed properly. #8047

CARLA version:0.9.15.2 Platform/OS:ubuntu 20.04 I am trying to build CARLA 0.9.15.2 following the https://carla.readthedocs.io/en/0.9.13/build_linux/ documentation. I have reached until the unreal engine setup and when I am running the ./Setup.sh && ./GenerateProjectFiles.sh && make command, I see the following error: make bash "/home/shinjinisarkar/UnrealEngine_4.26/Engine/Build/BatchFiles/Linux/Build.sh" CrashReportClient Linux Shipping
Fixing inconsistent case in filenames. Setting up Mono Running command : Engine/Binaries/DotNET/UnrealBuildTool.exe CrashReportClient Linux Shipping Using 'git status' to determine working set for adaptive non-unity build (/home/shinjinisarkar/UnrealEngine_4.26). Creating makefile for CrashReportClient (no existing makefile) ERROR: Platform Linux is not a valid platform to build. Check that the SDK is installed properly. make: *** [Makefile:302: CrashReportClient-Linux-Shipping] Error 6

My this path:UnrealEngine_4.26/Engine/Extras/ThirdPartyNotUE/SDKs/HostLinux/Linux_x64 is empty. How can I install SDK propely? I dwonloaded the appropriate toolchain from here https://dev.epicgames.com/documentation/en-us/unreal-engine/cross-compiling-for-linux?application_version=4.27 . But that is a .exe file. I unzipped it and ran the toolchain: UnrealEngine_4.26/Engine/Extras/ThirdPartyNotUE/SDKs/HostLinux/Linux_x64/v17_clang-10.0.1-centos7/build/scripts$ ./build_linux_toolchain.sh. But that also throws some error.

when I tried installing clang-8, it throws the following error: The following packages have unmet dependencies: clang-8 : Depends: libllvm8 (>= 1:8~svn298832-1~) but it is not going to be installed Depends: libstdc++-5-dev but it is not installable Depends: libgcc-5-dev but it is not installable Depends: libobjc-5-dev but it is not installable Depends: libclang-common-8-dev (= 1:8.0.1+svn369350-1~exp1~20200112113617.82) but it is not going to be installed Depends: libclang1-8 (= 1:8.0.1+svn369350-1~exp1~20200112113617.82) but it is not going to be installed Recommends: llvm-8-dev but it is not going to be installed Recommends: libomp-8-dev but it is not going to be installed E: Unable to correct problems, you have held broken packages.

This cannot be solved with sudo apt --fix-broken install

Please help me solve this issue.

Hi,

I have seen this issue come up a couple of times. It appears that the clang toolset is not being downloaded correctly when running the UE setup script. A workaround is to download Engine/Extras/ThirdPartyNotUE/SDKs/HostLinux/Linux_x64 manually from the link that can be found in the corresponding script.
