build error on net471 and startup crash on netcoreapp2.0

See original GitHub issue

distribution: ubuntu 18.04 LTS

I’m using VScode. When selecting osu! (Debug, net471) I get this build error:

/usr/share/dotnet/sdk/2.1.105/Sdks/Microsoft.NET.Sdk/build/Microsoft.PackageDependencyResolution.targets(167,5): error : Assets file '/home/lastexceed/dev/osu/osu-framework/osu.Framework/obj/project.assets.json' doesn't have a target for '.NETFramework,Version=v4.7.1'.

So I tried osu! (Debug, netcoreapp2.0) instead (since on windows that works just as good as net471 for me) and it builds successfully (0 errors, 0 warnings). Instead I get this exception on startup:

An unhandled exception of type 'System.TypeInitializationException' occurred in OpenTK.dll: 'The type initializer for 'OpenTK.DisplayDevice' threw an exception.'
 Inner exceptions found, see $exception in variables window for more details.
 Innermost exception 	 System.DllNotFoundException : Unable to load DLL 'gbm': The specified module or one of its dependencies could not be found.

Which log files do you need and where do I find them? Anything else I should provide?

First error is you not having the .net 4.7.1 sdk installed. second is opentk not being able to get a graphic context from your linux. you’re going to have to figure out why that is the case yourself.

try sudo apt install libgbm-dev then.

Just In case you need another dependencies, **EGL.dll -> sudo apt install libegl1-mesa-dev libdl.so -> sudo apt install libc6-dev
