Startup error about DirectX DLL

[ForNeVeR]

privately reported problem:

Probably we need DirectX 9 installed on the user's computer, or something like that?

TODO

• Bundle the libraries for use in dev mode
  • If impossible to bundle, figure out how to install, and add the information into the contributor guide
• Make sure the libraries are also available in the installed version of the game
  • Either open a new task for installer, or make sure they get bundled by either dotnet build or dotnet pack properly
• If we figure out anything new, add our information to this old question on Stack Overflow

So based on https://stackoverflow.com/a/28500257, I've prepared a minimal required DirectX redist:

dx_redist.zip

Gosh this is complicated.

Okay, the current plan then will be:

• Create a separate GitHub project
  • This will be a messy activity, but
• Push a script that will get these files from their origin, verify the hashes and pack them
  • Why so complicated? Because nobody should believe you, or me, or others in delivering the binaries, and thus the workflow of packing any artifact, even of this one-shot kind, should be fully automated and verifiable.
• Run the script and publish the files to NuGet.org
  • Why nuget? Because that's the best storage for binaries in .NET. Even if we aren't using them as direct assembly references.
• Download/reference the package on build
• Bundle it into the installer and run installation
• Add information about installation into the contributor guide

But then, have you taken a look at https://www.nuget.org/packages/Microsoft.DXSDK.D3DX? It seems to contain the libraries we need (at least D3DX9_43.dll is there), and the license seems to allow redistribution in the mode we want to.

Maybe let's start investigating that?

I've read this old article linked from the link you found, and it seems to indicate that DirectX is mostly available on the modern systems, with a small exception of D3DX, whatever the hell is that.
