Run dotnet core application on Raspberry Pi3 with CentOS UserLand

I am trying to run my AspNetCore 2 application on a Raspberry Pi3 Model B that runs CentOS arm edition (CentOS-Userland-7-armv7hl-Minimal-1708-RaspberryPi3). I installed both libunwind and libicu-devel with yum install, but when trying to run my application, I always get the following error:

[root@centos-rpi3 ~]# /opt/dotnet/dotnet my.dll

FailFast: Couldn't find a valid ICU package installed on the system. Set the configuration flag System.Globalization.Invariant to true if you want to run with no globalization support.

   at System.Environment.FailFast(System.String)
   at System.Globalization.GlobalizationMode.GetGlobalizationInvariantMode()
   at System.Globalization.GlobalizationMode..cctor()
   at System.Globalization.CultureData.CreateCultureWithInvariantData()
   at System.Globalization.CultureData.get_Invariant()
   at System.Globalization.CultureData.GetCultureData(System.String, Boolean)

   at System.AppDomain.PrepareDataForSetup(System.String, System.AppDomainSetup, System.Security.Policy.Evidence, System.Security.Policy.Evidence, IntPtr, System.String, System.String[], System.String[])
Aborted

For dotnet core installation I followed the guide described here (Task: Install the .NET Core Runtime on the Raspberry Pi): https://blogs.msdn.microsoft.com/david/2017/07/20/setting_up_raspian_and_dotnet_core_2_0_on_a_raspberry_pi/

Any ideas why dotnet core throws this error?

When running on Linux, ICU is used to get the time zone display name. It appears that CentOS 7 is not including "libicu" as well which is Required To Run dotnetcore.

Possible Solutions:

  1. Install libicu sudo yum install libicu as mentioned here
  2. Turn on Invariant Mode.

this worked for me:

 sudo vi /opt/microsoft/powershell/6.1.0/pwsh.runtimeconfig.json

 { "runtimeOptions": { "configProperties": { "System.Globalization.Invariant": true } } }

I solved the problem by installing the following two packages (on ubuntu 16.04)

apt-get install libunwind8 icu-devtools

I had the same problem. I tried to run a self-contained dotnet core 2.0 app on an Ubuntu core. I got it work when i set the "System.Globalization.Invariant": true.

There is a File called .runtimeconfig.json

In this File you need to put the following in:

  {
  "runtimeOptions": {
    "configProperties": {
      "System.Globalization.Invariant": true
    }
  }
}

Then it should work.
