2019-08-05compat/cuda: Change inclusion guardsAndreas Rheinhardt
cuda_runtime.h as well as dynlink_loader.h used nonstandard inclusion guards with an AV_ prefix, although these files are not in an libav*/ path. So change the inclusion guards and adapt the ref file of the source fate test accordingly.

2019-08-04build: add support for building CUDA files with clangRodger Combs
This avoids using the CUDA SDK at all; instead, we provide a minimal reimplementation of the basic functionality that lavfi actually uses. It generates very similar code to what NVCC produces. The header contains no implementation code derived from the SDK. The function and type declarations are derived from the SDK only to the extent required to build a compatible implementation. This is generally accepted to qualify as fair use. Because this option does not require the proprietary SDK, it does not require the "--enable-nonfree" flag in configure.

2019-05-04compat/avisynth: update headersStephen Hutchinson
As part of the update, it is now possible to test 32-bit GCC builds of AviSynth+ with FFmpeg by using the AVS_WIN32_GCC32 define. Due to different calling conventions between MSVC and GCC regarding 32-bit Windows, this is unfortunately necessary.

2018-02-27compat: remove in-tree NVidia headersTimo Rothenpieler
External headers are no longer welcome in the ffmpeg codebase because they increase the maintenance burden. However, in the NVidia case the vanilla headers need some modifications to be usable in ffmpeg therefore we still provide them, but in a separate repository. The external headers can be found at https://git.videolan.org/?p=ffmpeg/nv-codec-headers.git Fate-source is updated because of the deleted files, and dynlink_loader.h license headers were updated with the standard FFmpeg headers.

2017-12-26w32pthreads: always use Vista+ API, drop XP supportwm4
This removes the XP compatibility code, and switches entirely to SWR locks, which are available starting at Windows Vista. This removes CRITICAL_SECTION use, which allows us to add PTHREAD_MUTEX_INITIALIZER, which will be useful later. Windows XP is hereby not a supported build target anymore. It was decided in a project vote that this is OK.

This avoids having to use either "dumpbin -headers" to find out the current architecture, or pass $ARCH from configure to deduce it.

2017-04-13Support building C++ files with MSVCAaron Levinson
Made appropriate changes to be able to successfully build C++ files using a Visual C++ build on Windows. Based on an earlier patch by Kyle Schwarz. 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: a) Now calling set_ccvars CXX to cause the various CXX_ variables to be setup properly. For example, with MSVC (Microsoft Visual C++), this causes CXX_O to be set to -Fo$@ instead of using the default value. The default value does not work with Visual C++. This change will also have the impact of correcting CXX_O (and possibly CXX_C) for other compilers, although this is really only relevant for the Intel compiler, in addition to MSVC. b) Now using cl for the C++ compiler for the MSVC toolchain. This is currently only relevant for building the Blackmagic/Decklink-related files under avdevice. Signed-off-by: Hendrik Leppkes <h.leppkes@gmail.com>

2016-12-08compat/atomics: add typecasts in atomic_compare_exchange_strong()Wan-Teh Chang
The Solaris and Windows emulations of atomic_compare_exchange_strong() need typecasts to avoid compiler warnings, because the functions they call expect a void* pointer but an intptr_t integer is passed. Note that the emulations of atomic_compare_exchange_strong() (except the gcc version) only work for atomic_intptr_t because of the type of the second argument (|expected|). See http://en.cppreference.com/w/c/atomic: _Bool atomic_compare_exchange_strong( volatile A* obj, C* expected, C desired ); The types of the first argument and second argument are different (|A| and |C|, respectively). |C| is the non-atomic type corresponding to |A|. In the emulations of atomic_compare_exchange_strong(), |C| is intptr_t. This implies |A| can only be sig_intptr_t. Signed-off-by: Wan-Teh Chang <wtc@google.com>
