Can't build software, cmake file not found

Hi, i was setting the system up, succesfully got docker to setup...

aaron@aaron-TravelMate-P238-M:~/Downloads/ibex-demo-system$ sudo docker run -it --rm \
>   -p 6080:6080 \
>   -p 3333:3333 \

My issue is that, i could not run this set of commands.

cd /home/dev/demo
mkdir -p sw/build
pushd sw/build
cmake ..
make
popd

It produced this set of errors,

aaron@aaron-TravelMate-P238-M:~/Downloads/ibex-demo-system$ cd /home/dev/demo
cmake ..
make
popdbash: cd: /home/dev/demo: No such file or directory

I not sure what is dev in the cd /home/dev/demo command suppose to be. There is no cmake file in sw/build

aaron@aaron-TravelMate-P238-M:~/Downloads/ibex-demo-system/sw$ ls
build  c  common  rust

Those instructions are out of date. You need to make this directory: sw/c/build with the c. You should be able to find the instructions here:
https://github.com/lowRISC/ibex-demo-system#c-stack

Where did you find these old build instructions?

[Aaronyap2002]

i found it here. I assume this whole repository could not be use again? https://github.com/lowRISC/ibex-demo-system-labs/blob/main/lab1.md
Is it possible for me to skip this part of the instruction if i dont have the fpga for now. "If you want to program the FPGA from the container, let's find out which bus and device the Arty is on:"

[marnovandermaas]

Yes, you can skip those instructions if you don't have an FPGA. Those labs were written with an old version of the demo system: https://github.com/lowRISC/ibex-demo-system/releases/tag/v0.0.3
