"wifi-connect: cannot execute binary file" when running from balenaCloud main terminal

[charliesneath]

I have installed wifi-connect via this Dockerfile.template, but when trying to running the following command from the balenaCloud terminal for the container:

./wifi-connect --portal-ssid "NETWORK NAME"

I get the following error:

./wifi-connect: ./wifi-connect: cannot execute binary file.

Any ideas for possible issues here? Goal is to set a custom network name.

Do you see the wifi-connect connect executable in the folder you like to run it from (ls -al)? Is this a RPi device and what version? Can you paste the output of readelf -h /bin/bash.

Here's the how I see the file with of ls -al:

-rwxr-xr-x 1 root root 3815476 Nov  5 19:07 wifi-connect

This is a Raspberry Pi Zero W. Here's the output of readelf -h /bin/bash:

@charliesneath I made a copy/paste mistake. This is the command which output I need to take a look at: readelf -h ./wifi-connect

@majorz Output from readelf -h ./wifi-connect:

Did you solve this issue here? What is odd is that wifi-connect is marked as Type: DYN (Shared object file).
