From f3102160a1c0280ddd3e1873a50a2efddfe8c35b Mon Sep 17 00:00:00 2001 From: George Marques Date: Mon, 17 Oct 2016 13:40:45 -0200 Subject: [PATCH] Isolate XAudio2 driver Now it's possible to compile for Windows platform if wanted. It's supported only for Windows 8 or later, so it's not enabled by default. --- SConstruct | 1 + drivers/SCsub | 2 + drivers/xaudio2/SCsub | 9 +++++ .../xaudio2/audio_driver_xaudio2.cpp | 40 ++++++++----------- .../xaudio2/audio_driver_xaudio2.h | 24 +++++------ platform/windows/os_windows.cpp | 3 ++ platform/windows/os_windows.h | 6 +++ platform/winrt/SCsub | 1 - platform/winrt/detect.py | 2 +- platform/winrt/os_winrt.h | 4 +- 10 files changed, 53 insertions(+), 39 deletions(-) create mode 100644 drivers/xaudio2/SCsub rename platform/winrt/audio_driver_winrt.cpp => drivers/xaudio2/audio_driver_xaudio2.cpp (86%) rename platform/winrt/audio_driver_winrt.h => drivers/xaudio2/audio_driver_xaudio2.h (88%) diff --git a/SConstruct b/SConstruct index 14aba28818c..b808afa6309 100644 --- a/SConstruct +++ b/SConstruct @@ -132,6 +132,7 @@ opts.Add('openssl','OpenSSL library for openssl module (system/builtin)','builti opts.Add('libmpcdec','libmpcdec library for mpc module (system/builtin)','builtin') opts.Add('enet','ENet library (system/builtin)','builtin') opts.Add('glew','GLEW library for the gl_context (system/builtin)','builtin') +opts.Add('xaudio2','XAudio2 audio driver (yes/no)','no') opts.Add("CXX", "C++ Compiler") opts.Add("CC", "C Compiler") opts.Add("CCFLAGS", "Custom flags for the C++ compiler");
