Sdk: libhostpolicy.so not found when cross-compiling for Linux on Windows

Created on 1 May 2017 · 6Comments · Source: dotnet/sdk

Steps to reproduce

Create new ASP.NET Core 1.1 web app in Visual Studio 2017, using the "empty" template
Build and publish for Debian:

dotnet restore -r debian-x64
dotnet publish . -o "C:\TempPublish\helloworld" -c Release -r debian-x64

rsync to Debian server
Attempt to run the site:

ASPNETCORE_ENVIRONMENT=Production COREHOST_TRACE=1 dotnet WebApplication9.dll

Expected behavior

It works

Actual behavior

A fatal error was encountered. The library 'libhostpolicy.so' required to execute the application was not found

I do see libhostpolicy.so at /opt/dotnet/shared/Microsoft.NETCore.App/1.1.1/libhostpolicy.so; is there something I need to do to get it to use that one?

A couple of things here.

The right rid to use with debian is debian.8-x64, not debian-x64.
Second, taking in consideration the folder you put above, you need to check under bin/Release/netcoreapp1.1/debian-x64/publish/. I know the the output of the publish is pointing to the folder above, we have fixed that in the 2.0 tooling.

I have tried what I indicated above and I can see a file in the publish output folder and run it.

When you publish your app using a runtime, it becomes a self-contained app. In order to run a self-contained app, you don't execute it with dotnet . You run it by executing that should be available in the publish folder.

You use dotnet for portable apps (no runtime identifier).

Can you give that a go?

You run it by executing that should be available in the publish folder.

I'm getting a .dll file when I publish the site. How do I execute it?

Daniel15 on 1 May 2017

You should also be getting an executable named after your application in the publish folder. Can you maybe share the contents of your published output?

@livarcocc Here's a full directory listing of the publish folder after publishing a site called WebApplication12:

I checked bin\Release\netcoreapp1.1\debian-x64\ and it also doesn't contain an executable.

A couple of things here.

The right rid to use with debian is debian.8-x64, not debian-x64.
Second, taking in consideration the folder you put above, you need to check under bin/Release/netcoreapp1.1/debian-x64/publish/. I know the the output of the publish is pointing to the folder above, we have fixed that in the 2.0 tooling.

I have tried what I indicated above and I can see a file in the publish output folder and run it.

Thank you! It works when I use debian.8-x64. Did that change at some point? debian-x64 worked in previous releases.
