Bug 802087 – dev-dotnet/dotnet-sdk-bin: A fatal error occurred. The required library libhostfxr.so could not be found.

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Sam James 2021-07-14 01:55:11 UTC]

When running `dotnet run`:

```
[...]
A fatal error occurred. The required library libhostfxr.so could not be found.
If this is a self-contained application, that library should exist in [/home/sam/ircd/native/cmpctircd/cmpctircd/bin/Debug/netcoreapp5.0/].
If this is a framework-dependent application, install the runtime in the global location [/usr/share/dotnet] or use the DOTNET_ROOT environment variable to specify the runtime location or register the runtime location in [/etc/dotnet/install_location].

The .NET runtime can be found at:
  - https://aka.ms/dotnet-core-applaunch?missing_runtime=true&arch=x64&rid=gentoo-x64&apphost_version=5.0.7
sam@supercat ~/ircd/native/cmpctircd/cmpctircd $ equery f dev-dotnet/dotnet-sdk-bin | grep  libhost
/opt/dotnet-sdk-bin-5.0/host/fxr/5.0.7/libhostfxr.so
/opt/dotnet-sdk-bin-5.0/shared/Microsoft.NETCore.App/5.0.7/libhostpolicy.so
sam@supercat ~/ircd/native/cmpctircd/cmpctircd $
```

Putting /opt/dotnet-sdk-bin-5.0/ in /etc/dotnet/install_location works.

Is this still present in dotnet 6 and 7?

No response...
5.0 is already gone from the tree, so closing this.
