hellaenergy/o3de-dependencies

Description

License-clean COPR rebuilds of Open 3D Engine 3rdParty dependencies that aren't packaged in Fedora proper. Auto-enabled alongside any of the engine COPR projects (o3de, o3de-stabilization, o3de-development, o3de-experimental); end users typically don't enable this directly.

Installation Instructions

You probably don't need to enable this repo directly. It's auto-enabled by any of the five engine COPR projects (o3de, o3de-testing, o3de-stabilization, o3de-development, o3de-experimental) via their external_repos configuration. When you dnf copr enable hellaenergy/o3de2605 (or any sibling), dnf pulls deps from here automatically.

If you want to enable it standalone (e.g. you're packaging your own O3DE-derived project against this dependency stack):

sudo dnf copr enable hellaenergy/o3de-dependencies

What is this: license-clean Linux COPR rebuilds of the Open 3D Engine 3rdParty packages that aren't packaged in Fedora proper but are needed by the engine. Each package's source is o3de/3p-package-source/<package>/build_config.json's git_url + git_tag; we rebuild from those upstream sources rather than redistributing the prebuilt tarballs O3DE ships at packages.o3de.org.

Currently shipped (~12 packages):

• o3de-qt5 (5.15.2-rev9) -- O3DE's custom-patched Qt 5.15. LGPL-3.0 / GPL-3.0 (Qt) + Apache-2.0 (rev9 patches). Required because the bundled rev9 patches are load-bearing (system Qt5 cannot substitute).
• PhysX (5.x) -- BSD-3-Clause. Open-source since NVIDIA's 2022 release; not in Fedora.
• o3de-AWSNativeSDK, aws-iot-device-sdk-cpp-v2, aws-gamelift-server-sdk -- Apache-2.0. Specific versions O3DE pins; not in Fedora.
• azslc (1.8.x) -- Apache-2.0. O3DE's shader language compiler.
• ISPCTexComp -- MIT. Intel ISPC texture compressor.
• astc-encoder (3.2-rev2) -- Apache-2.0. ARM ASTC reference encoder.
• mikkelsen (1.0.0.4) -- Public domain. Tangent-space generator (Morten Mikkelsen).
• o3de2605-spirv-cross (1.3.275.0) -- Apache-2.0 / MIT. KhronosGroup SPIR-V to GLSL/HLSL/MSL cross-compiler. Engine shells out to /usr/bin/spirv-cross at asset-build time. ✓ Green as of 2026-05-07.
• o3de2605-dxc-spirv (1.8.2505.1-o3de) -- NCSA + Apache-2.0 (LLVM exception). Microsoft DirectXShaderCompiler (HLSL to SPIR-V), o3de fork at tag release-1.8.2505.1-o3de. Linux/SPIR-V-only build (no Windows DXIL signing tooling). Engine shells out to /usr/bin/dxc. ✓ Green as of 2026-05-08.
• o3de2605-mcpp-az (2.7.2_az.2-rev1) -- BSD-2-Clause (upstream Kiyoshi Matsui) + Apache-2.0 OR MIT (Amazon _az.2 patch series). License-clean rebuild of upstream mcpp 2.7.2 (abandonware-class C/C++ preprocessor, last upstream release 2008) + o3de/3p-package-source's 566-line _az.2 patch series. Library-link variant of the DXC-class pattern: the engine #includes <mcpp_lib.h> and links libmcpp.so into its binaries at build time (vs. spirvcross/dxc which are shelled out to as binaries). Ships /usr/bin/mcpp (CLI tool + man page), /usr/lib64/libmcpp.so.0.3.0 (main package), /usr/include/mcpp_lib.h + mcpp_out.h + libmcpp.a (devel subpackage). ✓ Green as of 2026-05-08.

Naming convention: all three Stage 2 packages use the o3deNNNN-<dep> form (where NNNN is the engine-major in YYMM, matching the engine RPM's o3deNNNN naming). This lets a future o3de2610-mcpp-az co-exist in the same project for the 26.10.x engine line, mirroring upstream's CDN model where multiple engine-major lines pin different package versions side-by-side. The 26.05.x point releases (.0/.1/.2/...) all share the same o3de2605-<dep> packages -- engine-team's empirical 3p-pin update cadence is a few times per year, not per release.

Rebuild strategy: each package is built with enable_net=false (so the SRPM has no upstream dependency at COPR build time). License-clean inputs only. Where O3DE upstream carries patches over the canonical source (e.g. DXC's -o3de tag, mikkelsen's git-snapshot rev), we apply those same patches in our SRPM.

Architectural shape: the engine COPR projects build with enable_net=true so cmake's LY_PACKAGE_SERVER_URLS fetcher can pull from packages.o3de.org for any 3rdParty packages we don't yet rebuild here. Each new SRPM that lands in this repo shifts one bundle from the packages.o3de.org CDN to here. The endgame is the CDN holding only the genuinely-restricted bundles (NvCloth, squish-ccr); everything else is either in Fedora (Stage 1 system swaps) or in this COPR repo (Stage 2 license-clean rebuilds).
