From 0f84d8dc497e73a8ad21ae51bc4912082f2d2454 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?R=C3=A9mi=20Verschelde?= Date: Wed, 16 Dec 2020 16:29:32 +0100 Subject: [PATCH] SCons: Add only selected platform's opts to env Otherwise we can get situations where platform-specific opts with the same name can override each other depending on the order at which platforms are parsed, as was the case with `use_static_cpp` in Linux/Windows. Fixes #44304. This also has the added benefit that the `scons --help` output will now only include the options which are relevant for the selected (or detected) platform. --- SConstruct | 24 +++++++++++------------- platform/iphone/detect.py | 3 --- platform/linuxbsd/detect.py | 3 --- platform/osx/detect.py | 4 +--- platform/server/detect.py | 2 -- platform/uwp/detect.py | 2 -- platform/windows/detect.py | 4 +--- 7 files changed, 13 insertions(+), 29 deletions(-) diff --git a/SConstruct b/SConstruct index 6aeb79e483..a816a079e0 100644 --- a/SConstruct +++ b/SConstruct @@ -17,7 +17,6 @@ import glsl_builders # Scan possible build platforms platform_list = [] # list of platforms -platform_opts = {} # options for each platform platform_flags = {} # flags for each platform active_platforms = [] @@ -44,7 +43,6 @@ for x in sorted(glob.glob("platform/*")): x = x.replace("platform/", "") # rest of world x = x.replace("platform\\", "") # win32 platform_list += [x] -
