Set up on Ubuntu might be incomplete

[tommythorn]

My x64 host is running Ubuntu 21.04 (Hirsute Hippo), fully up to date. I tried to map the step 1 to equivalent Ubuntu repos (I would need to this on a clean installation to complete this).

$ sudo apt install libjson-c-dev libcrypt-openssl-bignum-perl libevent-dev libmpc-dev libmpfr-dev python3-dev

but step python3 ./litex_setup.py init install --user fails with

$ python3 ./litex_setup.py init install --user
[checking litex_setup.py]...
[installing migen]...

On Fedora, python3-setuptools is a dependency of python3-devel, so you get it "for free". With commit 568513a I listed it explicitly, so hopefully that takes care of it.

Getting beyond this point, the instructions seems to assume you have a "litex-boards" directory. Where is that supposed to come from?

EDIT: ok, it installed it into the parent directory. That's a bit weird (and frankly not ideal). At least the documentation should mention this.

From litex_setup.py (Step 2 of the prerequisites).
