I have an ELF64 executable which I cannot execute in a Linuxulator environment; more precisely: a Linux jail.
In this jail, there is an Ubuntu 22.04, which was setup with sysutils/debootstrap.
The executable in question is called “patchelf-uninative” and fell out of a Yocto build. When trying to execute it, I get the following error:
Other executables from this Yocto build work just fine:
Both are ELF64 executables, which use the same interpreter:
respectively:
However, one is „version 1 (GNU/Linux)” and the other is „version 1 (SYSV)”. I have no clue what this means!
Does anyone know what is going on here?
PS: On native Ubuntu hosts both executables work fine, it's just in the Linuxulator environment.
