hidden depdendencies

[wucke13]

The readme does not list all dependencies. Some missing are:

• cpio
• file
• device-tree-compiler
• flex
• bison
• libgmp-dev
• libmpc-dev

Hi Thanks,

Aren't most of these already covered in the README?
flex and bison is included in build-essential.
But wondering about libgmp-dev libmpc-dev, any idea what requires this?

Ah, I'm not in a Debian based distro, so I don't have buld-essential. I don't recall exactly which software component was looking for those. I will try to find out.

I had a build fail on Ubuntu 24.04 that may be related. A snippet from the make output follows (my home directory is redacted). I am going to try installing the libmpc-dev package and see what I get.

EDIT: The build completed. I did not have to install any more than libmpc-dev (and the requirements in the README).
