.netcore `GLIBC_2.14' not found error on linux (RHEL)

Question

On windows 10, I created a .netCore (3.1.200) console application called helloWorld. Published it using the command:

dotnet publish -r linux-x64 --self-contained true

Copied over the publish folder to my linux machine (RHELS 6.10). Applied the executable permission chmod +x helloWorld

When I run the command, helloWorld , I am getting this error:

 helloWorld: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by helloWorld)

How can I resolve that?

Answer 1

Here's the answer for anyone else having the same issue.

publish command : dotnet publish -r rhel.6-x64 --self-contained true

When you run it on RHEL you will get another error saying "ICU is missing".

To Resolve that : Add a new file in your project called runtimeconfig.template.json

Add this to the file:

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

Now republish and re-run.
