Eden is also available as an [AUR package](https://aur.archlinux.org/packages/eden-git). If you are unable to build, either use that or compare your process to the PKGBUILD.
[`games-emulation/eden`](https://gitweb.gentoo.org/repo/proj/guru.git/tree/games-emulation/eden) is available in the GURU. This repository also contains some additional dependencies, such as mcl, sirit, oaknut, etc.
If you're having issues with building, always consult that ebuild.
Qt Widgets appears to be broken. For now, add `-DENABLE_QT=OFF` to your configure command. In the meantime, a Qt Quick frontend is in the works--check back later!
This is needed for some dependencies that call cc directly (tz):
```sh
echo '#!/bin/sh' >cc
echo 'gcc $@' >>cc
chmod +x cc
export PATH="$PATH:$PWD"
```
Default MESA is a bit outdated, the following environment variables should be set for a smoother experience:
```sh
export MESA_GL_VERSION_OVERRIDE=4.6
export MESA_GLSL_VERSION_OVERRIDE=460
export MESA_EXTENSION_MAX_YEAR=2025
export MESA_DEBUG=1
export MESA_VK_VERSION_OVERRIDE=1.3
# Only if nvidia/intel drm drivers cause crashes, will severely hinder performance
export LIBGL_ALWAYS_SOFTWARE=1
```
- Modify the generated ffmpeg.make (in build dir) if using multiple threads (base system `make` doesn't use `-j4`, so change for `gmake`).
- If using OpenIndiana, due to a bug in SDL2's CMake configuration, audio driver defaults to SunOS `<sys/audioio.h>`, which does not exist on OpenIndiana. Using external or bundled SDL2 may solve this.
- System OpenSSL generally does not work. Instead, use `-DYUZU_USE_BUNDLED_OPENSSL=ON` to use a bundled static OpenSSL, or build a system dependency from source.
It's recommended to do a `pkgman full-sync` before installing. See [HaikuOS: Installing applications](https://www.haiku-os.org/guides/daily-tasks/install-applications/). Sometimes the process may be interrupted by an error like "Interrupted syscall". Simply firing the command again fixes the issue. By default `g++` is included on the default installation.
GPU support is generally lacking/buggy, hence it's recommended to only install `pkgman install mesa_lavapipe`. Performance is acceptable for most homebrew applications and even some retail games.
For reasons unberknownst to any human being, `glslangValidator` will crash upon trying to be executed, the solution to this is to build `glslang` yourself. Apply the patch in `.patch/glslang/0001-haikuos-fix.patch`. The main issue is `ShFinalize()` is deallocating already destroyed memory; the "fix" in question is allowing the program to just leak memory and the OS will take care of the rest. See [this issue](https://web.archive.org/web/20251021183604/https://github.com/haikuports/haikuports/issues/13083).
For this reason this patch is NOT applied to default on all platforms (for obvious reasons) - instead this is a HaikuOS specific patch, apply with `git apply <absolute path to patch>` after cloning SPIRV-Tools then `make -C build` and add the resulting binary (in `build/StandAlone/glslang`) into PATH.
`cubeb_devel` will also not work, either disable cubeb or uninstall it.
Still will not run flawlessly until `mesa-24` is available. Modify CMakeCache.txt with the `.so` of libGL and libGLESv2 by doing the incredibly difficult task of copy pasting them (`cp /boot/system/lib/libGL.so .`)
`-lc++-experimental` doesn't exist in OpenBSD but the LLVM driver still tries to link against it, to solve just symlink `ln -s /usr/lib/libc++.a /usr/lib/libc++experimental.a`. Builds are currently not working due to lack of `std::jthread` and such, either compile libc++ manually or wait for ports to catch up.
The available OpenSSL port (3.0.17) is out-of-date, and using a bundled static library instead is recommended; to do so, add `-DYUZU_USE_BUNDLED_OPENSSL=ON` to your CMake configure command.
Install `pkgin` if not already `pkg_add pkgin`, see also the general [pkgsrc guide](https://www.netbsd.org/docs/pkgsrc/using.html). For NetBSD 10.1 provide `echo 'PKG_PATH="https://cdn.netbsd.org/pub/pkgsrc/packages/NetBSD/x86_64/10.0_2025Q3/All/"' >/etc/pkg_install.conf`. If `pkgin` is taking too much time consider adding the following to `/etc/rc.conf`:
System provides a default `g++-10` which doesn't support the current C++ codebase; install `clang-19` with `pkgin install clang-19`. Or install `gcc14` (or `gcc15` with current pkgsrc). Provided that, the following CMake commands may work:
[parallel/spirv-tools](https://iso.us.netbsd.org/pub/pkgsrc/current/pkgsrc/parallel/spirv-tools/index.html) isn't available in binary form and must be build from source.
Such that glslang is not available on NetBSD, to circumvent this simply build glslang by yourself:
However, pkgsrc is highly recommended, see [getting pkgsrc](https://iso.us.netbsd.org/pub/pkgsrc/current/pkgsrc/doc/pkgsrc.html#getting). You must get `current` not the `2025Q2` version.
This may have unforeseen consequences of which we don't need to worry about for now.
Default `g++` (and the libstdc++) is too outdated - so install `gcc14` and redirect CMake to the new compiler toolchain `-DCMAKE_CXX_COMPILER=gcc14 -DCMAKE_C_COMPILER=g++14`.
There is also `llvm18` and use `-DCMAKE_CXX_COMPILER=clang++18 -DCMAKE_C_COMPILER=clang18` (note the `18` suffix at the end). NOTE: It doesn't have an updated libcxx so `<span>` will be missing, either build it manually or use gcc.
The package install may randomly hang at times, in which case it has to be restarted. ALWAYS do a `sudo pkg update` or the chances of it hanging will be close to 90%. If "multiple" installs fail at once, try installing 1 by 1 the packages.
When CMake invokes certain file syscalls - it may sometimes cause crashes or corruptions on the (kernel?) address space - so reboot the system if there is a "hang" in CMake.
