From c7b53c03ae7f7feb45a6023ee5cf764025ebb5e1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?R=C3=A9mi=20Verschelde?= Date: Thu, 17 Dec 2020 16:01:36 +0100 Subject: SCons: Add explicit dependencies on thirdparty code in cloned env Since we clone the environments to build thirdparty code, we don't get an explicit dependency on the build objects produced by that environment. So when we update thirdparty code, Godot code using it is not necessarily rebuilt (I think it is for changed headers, but not for changed .c/.cpp files), which can lead to an invalid compilation output (linking old Godot .o files with a newer, potentially ABI breaking version of thirdparty code). This was only seen as really problematic with bullet updates (leading to crashes when rebuilding Godot after a bullet update without cleaning .o files), but it's safer to fix it everywhere, even if it's a LOT of hacky boilerplate. --- modules/theora/SCsub | 16 ++++++++++++++-- 1 file changed, 14 insertions(+), 2 deletions(-) (limited to 'modules/theora') diff --git a/modules/theora/SCsub b/modules/theora/SCsub index a01e65b4b0..6038ea086a 100644 --- a/modules/theora/SCsub +++ b/modules/theora/SCsub @@ -6,6 +6,9 @@ Import("env_modules") env_theora = env_modules.Clone() # Thirdparty source files + +thirdparty_obj = [] + if env["builtin_libtheora"]: thirdparty_dir = "#thirdparty/libtheora/" thirdparty_sources = [ @@ -80,7 +83,16 @@ if env["builtin_libtheora"]: env_thirdparty = env_theora.Clone() env_thirdparty.disable_warnings() - env_thirdparty.add_source_files(env.modules_sources, thirdparty_sources) + env_thirdparty.add_source_files(thirdparty_obj, thirdparty_sources) + env.modules_sources += thirdparty_obj + # Godot source files -env_theora.add_source_files(env.modules_sources, "*.cpp") + +module_obj = [] + +env_theora.add_source_files(module_obj, "*.cpp") +env.modules_sources += module_obj + +# Needed to force rebuilding the module files when the thirdparty library is updated. +env.Depends(module_obj, thirdparty_obj) -- cgit v1.2.3
