additional pre-requisites and dependencies for building sdk

[ikuz]

Here are some additional tools and packages I had to install to get build_sdk.py to work on a fresh Ubuntu 18.04 install. (these are based on using the initial public release - I notice some more recent updates have added some of the missing python dependencies)

• pandoc: sudo apt install pandoc
• pdflatex: sudo apt install texlive-latex-base
• cmake: sudo apt install cmake - see note below about wrong cmake version
• ninja: sudo apt-get install ninja-build
• gcc-aarch64-linux-gnu: sudo apt-get install gcc-aarch64-linux-gnu
• dtc: sudo apt-get install device-tree-compiler
• pyyaml: ./pyenv/bin/pip install pyyaml
• pyfdt: ./pyenv/bin/pip install pyfdt
• jinja2: ./pyenv/bin/pip install jinja2
• xmllint: ./pyenv/bin/pip install libxml2-utils
• ply: ./pyenv/bin/pip install ply

Note about cmake:

• cmake >= 3.13 is required. apt installs cmake 3.10.2
• instructions for newer cmakes:
  • sudo apt-get update
  • sudo apt-get install apt-transport-https ca-certificates gnupg software-properties-common wget
  • wget -O - https://apt.kitware.com/keys/kitware-archive-latest.asc 2>/dev/null | sudo apt-key add -
  • sudo apt-add-repository 'deb https://apt.kitware.com/ubuntu/ bionic main'
  • sudo apt-get install cmake

Note about docs:

• I still got errors trying to build documentation, Font T1/cmr/m/n/10.95=ecrm1095 at 10.95pt not loadable: Metric (TFM) file not found.
• so I commented out build_doc and just built the sdk

@ikuz Massive thanks for compiling this list! Saved me a bunch of time when trying to build.

Regarding the following:

I still got errors trying to build documentation, Font T1/cmr/m/n/10.95=ecrm1095 at 10.95pt not loadable: Metric (TFM) file not found.

I found that sudo apt installing the following fixed that and another related issue:

• texlive-fonts-recommended
• texlive-formats-extra

Also, libxml2-utils should be installed via apt instead of via pip as described in your post:

xmllint: ./pyenv/bin/pip install libxml2-utils

In terms of Python dependencies, I also had to install the following packages via pip:

• six
• future

Hope this helps others out.

Thanks @ikuz and @ptrk8 - I'm on archlinux and resorted to installing all the deps in a container (see https://github.com/perpen/sel4cp-container)
