Run dotnet core application on Raspberry Pi3 with CentOS UserLand

Question

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.

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?

It says the following: `[root@centos-rpi3 ~]# rpm -q libicu libicu-50.1.2-15.el7.armv7hl` — Márton, Nov 07 '17 at 17:55
I am totally confused now. It should be picking that one up. Maybe it is looking in the wrong place. Can you try an `strace`? — omajid, Nov 08 '17 at 18:26
According to strace dotnet core is looking for libicu version 52 or higher, which is a problem, since the highest version I could find for this particular CentOS version is 50 — Márton, Nov 12 '17 at 20:52
For a hack, try creating a symlink for version 52 that points back to version 50. On x86_64 platforms, version 50 is picked up and used. It might work on arm too. — omajid, Nov 12 '17 at 23:43
This was my first idea when I saw the strace, but unfortunately it did not solve the problem. Dotnet Core is looking for a function that has _52 suffix and that one cannot be found in version 50 — Márton, Nov 13 '17 at 11:38
I would suggest filing a bug at https://github.com/dotnet/cli/, then. — omajid, Nov 13 '17 at 15:20

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.

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

apt-get install libunwind8 icu-devtools

this worked for me:

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

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

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:

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

Same for CentOS 8, see https://github.com/dotnet/core/blob/master/Documentation/linux-prereqs.md for more distros – Nomada Jan 23 '20 at 13:00
