I was successfully able to run SEQ6 on a pi 4 with Raspbian. My pi was a 4gb but it should work on other versions.
EDIT: SEQ runs on Buster but not newer images. Please install buster and read the edits to get it to work.
as root or sudo these commands
apt-get update
apt-get upgrade
apt-get install xdm x11-apps libx11-dev libvte9 qt4-default subversion libtool make automake libpcap-dev libxext-dev
It will ask which window manager you want. Keep lightdm.
After it is done, reboot.
--------------------------------------------------------------------------------------------------------
If you want to use the pi as an access point for your laptop, you will need to install Rasp-ap.
curl -sL https://install.raspap.com | bash
https://raspap.com
reboot and set it up.
-------------------------------------------------------------------------------------------------------
./configure && make && make install
That is it! It is a lot simpler than the pi 3.
Edit: added libx11-dev that was not installed. Added it to the list. My default install had libxext-dev already installed, but if configure fails, try installing it.
Edit2: re-added libxext-dev to the list. I dont know why mine said it was installed already and someone else said it wasnt. It cant hurt, at worst it will say it was already installed.
New: add libice-dev to the list.
