Hello,
I’m trying to create a normal QEmu (x86-64) Image, which I can let run in Virtualbox. As a addition I deployed .NET Core, which I got from this side:
https://dotnet.microsoft.com/download/dotnet-core/thank-you/runtime-aspnetcore-3.1.1-linux-x64-binaries
But I can’t execute it:
----------------------------
root@qemux86-64:/usr/share/dotnet# ./dotnet
-sh: ./dotnet: No such file or directory
But it is there:
------------------
root@qemux86-64:/usr/share/dotnet# ls -lh
total 116K
-rw-r--r-- 1 root root 1.1K Feb 10 02:33 LICENSE.txt
-rw-r--r-- 1 root root 31K Feb 10 02:33 ThirdPartyNotices.txt
-rwxr-xr-x 1 root root 72K Feb 10 02:33 dotnet
drwxr-xr-x 3 root root 4.0K Feb 10 02:36 host
drwxr-xr-x 4 root root 4.0K Feb 10 02:36 shared
It tried to get more information about the dotnet-executable

I compared those values with that from Python, which does run on this system

================================================================================
The only difference I found, is that Python is a “ELF 64-bit LSB pie executable” whereas dotnet is a “ELF 64-bit LSB executable”. I tried to turn that PIE (seemed
to be a gcc option: --enable-default-pie) feature of, but that didn’t work well, and I couldn’t find a way to remove it.
