From 722cbb5f6544323430d883212ac2e38c4eb94e5f Mon Sep 17 00:00:00 2001 From: Aaron Levinson <alevinsn@aracnet.com> Date: Wed, 12 Apr 2017 16:33:39 -0700 Subject: [PATCH] Made appropriate changes to be able to successfully build C++ files using a Visual C++ build on Windows. Purpose: Made appropriate changes to be able to successfully build C++ files using a Visual C++ build on Windows. Note that this is a continuation of the "fixes w32pthreads to support C++" aspect of Kyle Schwarz's "Remove pthread dependency" patch that is available at https://patchwork.ffmpeg.org/patch/2654/ . This patch wasn't accepted, and as far as I can tell, there was no follow-up after it was rejected. Notes: Used Visual Studio 2015 (with update 3) for this. Comments: -- compat/w32pthreads.h: Made appropriate changes to w32pthreads.h to get it to build when it is being included in a C++ file and built with Visual C++. This is mostly a copy of Kyle Schwarz's patch as described above. -- configure: Made minor modifications to MSVC (Microsoft Visual C++) toolchain section to make sure that -Fo$@ is used when building object files but when the C++ compiler is used and also to use cl for the default C++ compiler. This is currently only relevant for building the Blackmagic/Decklink-related files under avdevice. --- compat/w32pthreads.h | 24 ++++++++++++------------ configure | 3 +++ 2 files changed, 15 insertions(+), 12 deletions(-)
