title: Qt program not executable (Exec format error) despite binary and system architecture both x86_64
body: <p>I am trying to get a hello world example working with the latest version of Qt on Ubuntu 20.04. I am compiling via the automatically generated <code>Makefile</code> produced by <code>qmake</code>. Once compiled, the binary does not have sufficient permissions. After granting permissions I get an <code>Exec format error</code>. Running <code>file</code> on the output executable returns <code>ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not stripped</code>. Running <code>uname -mpi</code> on my machine outputs <code>x86_64 x86_64 x86_64</code>. It seems to me like the architecture and binary are compatible but for some reason I get the <code>Exec format error</code>. Am I misunderstanding something or do I need to configure the compilation step in the <code>Makefile</code> to be compatible with my hardware?</p>
