Hi Kaj,
I am including the CASPER community in this email thread as it applies to
everyone.
Interesting, so I have run into another person with the same virtualenv
install issue that you encountered as shown in red below. I have been
helping him debug too on a new machine and I am pleased to say that his
virtualenv is now working. It seems like the new Ubuntu 16.04LTS installs
come with a newer version of virtualenv which is not compatible with python
3.5 - fun, fun, fun. This definitely applies to all Casperites who are
installing the toolflow on their new machines.
kjwiik@casperx:~/work$ virtualenv -p python3 casper_venv

I want you to check the following versions for me:
1) virtualenv -> type "virtualenv --version" at the prompt. You should get
16.7.5. If not then you will need to uninstall the virtualenv by typing:
"pip3 uninstall virtualenv" and then we will need to install the 16.7.5
version. To install an exact version then type: "pip3 install
virtualenv==16.7.5". The use of "sudo" with "-H" arguments may or may not
be needed. The installs will guide you.
2) What is your Ubuntu 16.04LTS version? -> type "lsb_release -a". I am
using Ubuntu 16.04.7 LTS, Xenial.
3) What is your pip3 version? -> type "pip3 --version". I am using pip
8.1.1.
4) What is your python version? -> type: "python --version". I am using
python version 2.7.12
5) What is your python3 version? -> type: "python3 --version". I am using
python3 version 3.5.2.
Please make sure all these versions are the same before continuing. I
suspect that the latest Ubuntu 16.04LTS installs have made some upgrades
that are incompatible.
Once these versions are as above then try the following step to create the
virtual env:
1) Type: "virtualenv -p python3 <name_of_virtual_env>". This should create
a folder with the same name as "name_of_virtual_env". There should be no
issues with the install. It should complete without issues.
2) To activate the virtual environment -> type: "source
<path_to_folder>/<name_of_virtual_env>/bin/activate
3) Once activated then you can deactivate it by typing "deactivate".
4) If the virtual environment is activated then if you type "python" you
should get version 3.5.2
5) If the virtual environment is deactivated then if you type "python" you
should get 2.7.12.
I think if you can achieve this then you are ready to install the toolflow
by following these steps:
1)
https://casper-toolflow.readthedocs.io/en/latest/src/Installing-the-Toolflow.html#
2)
https://casper-toolflow.readthedocs.io/en/latest/src/How-to-install-Matlab.html
3)
https://casper-toolflow.readthedocs.io/en/latest/src/How-to-install-Xilinx-Vivado.html
4)
https://casper-toolflow.readthedocs.io/en/latest/src/Configuring-the-Toolflow.html
5)
https://casper-toolflow.readthedocs.io/en/latest/src/Running-the-Toolflow.html
6) https://casper-toolflow.readthedocs.io/projects/casperfpga/en/latest/ (This
is how to install casperfpga)
@Jonathon Kocz <[email protected]> : we will need to update the docs to
reflect this new information. I will wait until both parties have working
systems before updating the ReadtheDocs. One of the parties is using a
proxy and has some additional information on how to install with a proxy
that will be useful for other casperites.
I hope this helps!
