Hypridle Core Dumped - Illegal Hardware Instruction

[ksolowoniuk]

Hi there, I'm running Hyprland on Freebsd 14.1. Everything has been really good but I can't get Hypridle to work. exec-once = hypridle leaves a coredump in my home directory. The following is what I get trying to run hypridle from the terminal:

// hypridle

zsh: illegal hardware instruction (core dumped) hypridle

hypridle.core

please don't post core files, they are useless.

Anyways, illegal hardware instruction errors are impossible to be produced by C++ code, which likely means your hyprlock is compiled wrong. Please pull git and compile manually.

LLDB'ed a debug build and figured out it's the same issue as hyprwm/xdg-desktop-portal-hyprland#207

FreeBSD's libc is catching a call to mutex::unlock() on a mutex that's not locked. Apparently it's UDB when trying to do that. I can confirm that calling mutex::try_lock() before the while loop at src/core/Hypridle.cpp:134 solves the issue. I hate how hacky it is, but it works for now.

EDIT: Should have probably added the line...

// src/core/Hypridle.cpp:134
m_sEventLoopInternals.loopRequestMutex.try_lock();
while (1) {
  // ...
}

ok that is stupid, it should abort...
