What happened?

Hello, can anyone tell me how to configure the profile for s390x? I've been trying for three hours but haven't succeeded. I was able to run the teamserver and generate a payload successfully on an x86 machine, but I keep failing in generating the payload on s390x. I am completely out of ideas. I am seeking anyone’s help. Thank you again.

I tried downloading the s390x version from musl.cc and attempted to configure it in the profile, but I still couldn't generate the payload. Can anyone give me some guidance?"

MY profile

    Host = "0.0.0.0"

    user "G4ape" {

# this is optional. if you dont use it you can remove it.

Can someone try to help me? I'm now trying to reinstall GCC on the s390x platform.
And may I ask if a VNC component will be added in the future for real-time preview, or could you give me some guidance so I can learn to develop a new script?
This is really a great project; it's hard to imagine it's supported by just one person. I really like this project.
