NextPVR on M1 Mac?

[timbo3344]

I have an M1 Mac mini and cannot get NextPVR to install and run.  Is there a way to make it work?

Did you install via Rosetta?

I assumed Rosetta just kicks in when needed. I'm techy, but not a programmer so Github stuff is a little beyond me

How would I install with Rosetta?

[mvallevand]

Via a Rosetta shell instead of a Terminal shell.

so before trying that.  I found an article that said that install .net 6.0 which I did, but now it seems that might be my problem.  Now when I try to run it in Rosetta shell I get this:

Failed to load Q, error: dlopen(/usr/local/share/dotnet/host/fxr/6.0.0-preview.2.21154.6/libhostfxr.dylib, 1): no suitable image found.  Did find:

  - Installing .NET Core prerequisites might help resolve this problem.

but I have no idea how to uninstall 6.

or is there a way to force NextPVR to run on the earlier .net I also have installed?

[timbo3344]

I got it uninstalled. Installed 3.1 again. Ran it in a rosetta shell and got the same error as I had originally. It starts to run and then a get a popup saying dotnet quit unexpectedly with a huge crashlog

NextPVR is currently built to use the .net core 3.1 runtime. Microsoft does not currently natively support this runtime on the M1, but from what I've read, this is usuable via Rosetta.

Later this year I will move NextPVR to either .net 5 or 6, the later of which is supposed to be natively supported on the M1.

What output and/or error did you get when you tried this?

[timbo3344]

it pops up a GUI window that starts with

dotnet quit unexpectedly.

and here's some of the log but it goes on forever after this:

Unfortunately that error doesn't tell me much about what is happening. It's somewhere in the bowels of dotnet.
