How to get Vitis HLS Vision 2021.2 running on Arch Linux

This information will probably be outdated once you read it, because Arch is a rolling distro, which means that packages get updated almost immediately when they get released. Old software like Xilinx tools depend on specific versions of these libraries and they don't like newer versions. This means that you'll have to downgrade some packages to get Xilinx tools like Vitis HLS working on your Arch machine.

1. Downgrade opencv to 4.4.0-3
2. Downgrade tbb to 2020.3
3. Downgrade openexr (they changed name November 2021 so the Xilinx tools still refer to it as libIlmImf) to 2.5.5-1

Introduction

It took me two hours to find out that I hadn't properly initialized a dynamic array that was allocated on the stack. Valgrind is truly an awesome tool, and in conjuction with GDB it is really powerful. I will have probably forgotten how to use Valgrind in a week from now, so that's why I'm writing this quick summary on how I managed to debug the issue. I hope it's useful for future reference.

Arch server installation

Archlinux is perfect for minimal servers because it does not come with bloatware programs like other OSes (ex. centos, rhel, deb, etc) do and therefore reduces the potential attack surface. One of the biggest benefits due to Arch's rolling release cycle is that you will get security updates within hours, instead of days to months if you're using ubuntu, centos, etc. However, it must be configured in a right manner and great care must be taken on every action.

Installation guide

1. Boot into Live ISO and switch to root user (su) if not already using
2. Create root and swap partitions on disk you want to use.

Everything wrong with PHP

• In object-oriented programming, constructors aren't functions. But in PHP they are declared using function __construct. Weird.
• No annotations/attributes! How are we supposed to provide metadata about class members?! (and no, phpdoc isn't an annotation, fuck off.)
• Namespace separators are a backslash, which means they have to be escaped in JSON and other languages.
• Why do constructors start with __? I've never used this key on my keyboard before.
• No strict type enforcement / non-null types.
• No casting to arrays, or specific types.
• No typed variables within method signatures.
• No mixed varargs.
