From: Andrew Udvare Date: Mon, 9 Feb 2026 01:00:00 -0500 Subject: [PATCH] Use system-installed premake when XENIA_USE_SYSTEM_PREMAKE is set When XENIA_USE_SYSTEM_PREMAKE is set, tools/build/premake.py uses premake5 from PATH and does not build premake from source. For ebuild builds, set the variable and depend on dev-util/premake:5. --- tools/build/premake.py | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) diff --git a/tools/build/premake.py b/tools/build/premake.py --- a/tools/build/premake.py +++ b/tools/build/premake.py @@ -21,6 +21,21 @@ premake_submodule_path = os.path.join(root_path, "third_party", "premake-core") premake_path = premake_submodule_path +def use_system_premake(): + """Use system-installed premake5 when XENIA_USE_SYSTEM_PREMAKE is set.""" + if os.environ.get("XENIA_USE_SYSTEM_PREMAKE", "").strip() in ("", "0"): + return None + premake5 = "premake5" + if sys.platform == "win32": + premake5 += ".exe" + for path in os.environ.get("PATH", "").split(os.pathsep): + path = path.strip('"') + exe = os.path.join(path, premake5) + if os.path.isfile(exe) and os.access(exe, os.X_OK): + return exe + return None + + def setup_premake_path_override(): global premake_path premake_path = premake_submodule_path @@ -50,6 +65,12 @@ setup_premake_path_override() def main(): + # When XENIA_USE_SYSTEM_PREMAKE is set, use system premake5 only (do not build). + system_premake = use_system_premake() + if system_premake is not None: + return_code = shell_call([system_premake] + sys.argv[1:], throw_on_error=False) + sys.exit(return_code) + # First try the freshly-built premake. premake5_bin = os.path.join(premake_path, "bin", "release", "premake5") if not has_bin(premake5_bin):
