Tips & tricks, common issues

using ccache/sccache

Precompiled headers (PCH) was enabled by default, this would most likely invalidate the compiler cache if any of the upstream header files change. To disable PCH, add the meson build option -Db_pch=false to build().

build() {
  ...
  meson setup build \
    -D b_pch=false
  ...
}

Build with specific pull requests

Use pick_mr <pull request number> at the end of prepare() to merge pull requests locally. For example, to merge https://github.com/hyprwm/Hyprland/pull/6268, use

prepare() {
    ...

    pick_mr 6268
}

Enable legacy renderer

In the build() function, add -D legacy_renderer=true to meson setup

Compilation errors

If you encounter compilation errors, try the following first:

• If errors are raised by generated source files under protocols/, such as protocols/linux-dmabuf-v1.hpp, then rebuild or install hyprwayland-scanner-git;
• Compile with makepkg --cleanbuild.

Symbol not declared

Errors like

• <symbol> was not declared in this scope
• <symbol> has not been declared

are usually caused by missing headers. Please consider reporting this upstream or creating a pull request if it has not already been done.

need help here, what should i do with this

need to adjust a bit after commit

probably just

sed -E -i -e "s/(soversion = .*$)/soversion = 13032/g" subprojects/wlroots/meson.build

instead of patch and

mv "$pkgdir/usr/include/wlr" "$pkgdir/usr/include/hyprland/wlroots"

in package()

@UltraBlack Yes, clang works.

But you will need libc++, since clang-16 in the repo doesn't compile hyprland with libstdc++. See https://aur.archlinux.org/packages/hyprland-git?O=70#comment-937055

It is in the dependencies, but I don't think artix report has it.

https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=hyprland-git#n34

After the latest update, I get an error related to the lack of libsystemd. I'm on Artix Linux with s6 as the init, been using this package for a while without any problems. If you want to add it as a hard dep, you should at least add it to the dependencies.

meson.build:54:14: ERROR: Dependency "libsystemd" not found, tried pkgconfig and cmake

could you use clang instead of gcc for compiling this package? The gcc version on the arch arm mirrors is so outdated that this isn't buildable, and for months now. Clang allegedly works. They have a guide here

I sadly haven't been able to get this to work myself, but I might be missing something Edit: No idea what it was but it's using clang now. I added the following to the meson command: CC=clang CXX=clang++ meson setup build ... -Dcpp_args=--stdlib=libstdc++ -Dc_args=-Wno-unused-command-line-argument", it's still crashing at a compiler error. Weird...

This PKGBUILD doesn't enable the systemd meson feature, which breaks user units (such as xdg-desktop-portal) if certain environment variables aren't set inside them, such as WAYLAND_DISPLAY

Subject: [PATCH] Enable systemd build option

This sets USES_SYSTEMD which does a bunch of useful things such as set
the WAYLAND_DISPLAY and a bunch of other useful variables for user
systemd units.
