Bringing Python 3.7 to the Chromebook

All of this is done in the ‘penguin’ container of ‘termina’ (e.g. enable ‘linux’ on the chrome settings). By default its Debian 9.6, and runs Python 3.5. But you might want to run e.g. Quart, which wants a newer rev for some asyncio. So, here goes.

Step 1: Install dev essentials, as root (e.g. sudo)

apt-get update
apt-get install -y build-essential libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev zlib1g-dev

Step 2: Install clang/llvm, as root (e.g. sudo)

echo deb http://apt.llvm.org/stretch/ llvm-toolchain-stretch-7 main > /etc/apt/sources.list.d/llvm.list
wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key|sudo apt-key add -

apt-get update
apt-get install -y libllvm-7-ocaml-dev libllvm7 llvm-7 llvm-7-dev llvm-7-doc llvm-7-examples llvm-7-runtime clang-7 clang-tools-7 clang-7-doc libclang-common-7-dev libclang-7-dev libclang1-7 clang-format-7 python-clang-7 libfuzzer-7-dev lldb-7 lld-7 libc++-7-dev libc++abi-7-dev libomp-7-dev

update-alternatives --install /usr/bin/llvm-profdata llvm-profdata /usr/bin/llvm-profata-7 90
update-alternatives --install /usr/bin/clang clang /usr/bin/clang-7 90
update-alternatives --install /usr/bin/clang++ clang++ /usr/bin/clang++-7 90

Step 3: Get & Install Python

wget https://www.python.org/ftp/python/3.7.1/Python-3.7.1.tgz
tar -xzvf Python-3.7.1.tgz
./configure --enable-optimizations
make -j4
make install

And you have yourself some Python 3.7! Pip on!
