* ffbuild/common: Fix CPPFLAGS applied for compiling C++ filesAndreas Rheinhardt2022-05-24
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, $(CPPFLAGS) and $(CFLAGS) are prepended to CXXFLAGS (the flags for compiling C++) like this: CXXFLAGS := $(CPPFLAGS) $(CFLAGS) $(CXXFLAGS) Using ":=" creates a simply expanded variable, i.e. the values of the variable at the time of assignment are used and later modifications to them are ignored (using a recursively expanding variable (i.e. "=" instead of ":=") is not really possible here, as there would be an infinite loop when evaluating CXXFLAGS). Yet we perform later additions to CPPFLAGS: HAVE_AV_CONFIG_H and BUILDING_libfoo are defined. These do not reach C++ compilations. To fix this a trick is employed to prepend to a recursively expanded variable while keeping it recursively expanded. There are two practical consequences of this: C++ files now no longer include the version.h header, but only the version_major.h header of their library, saving some recompilations. Furthermore, they now get some optimized math functions (namely the ones from lavu/intmath.h instead of the ones from lavu/common.h). (av_parity() is the only one for which it makes a difference.)

* Makefile: Redo duplicating object files in shared buildsAndreas Rheinhardt2022-01-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case of shared builds, some object files containing tables are currently duplicated into other libraries: log2_tab.c, golomb.c, reverse.c. The check for whether this is duplicated is simply whether CONFIG_SHARED is true. Yet this is crude: E.g. libavdevice includes reverse.c for shared builds, but only needs it for the decklink input device, which given that decklink is not enabled by default will be unused in most libavdevice.so. This commit changes this by making it more explicit about what to duplicate from other libraries. To do this, two new Makefile variables were added: SHLIBOBJS and STLIBOBJS. SHLIBOBJS contains the objects that are duplicated from other libraries in case of shared builds; STLIBOBJS contains stuff that a library has to provide for other libraries in case of static builds. These new variables provide a way to enable/disable with a finer granularity than just whether shared builds are enabled or not. E.g. lavd's Makefile now contains: SHLIBOBJS-$(CONFIG_DECKLINK_INDEV) += reverse.o Another example is provided by the golomb tables. These are provided by lavc for static builds, even if one uses a build configuration that makes only lavf use them. Therefore lavc's Makefile contains STLIBOBJS-$(CONFIG_MXF_MUXER) += golomb.o, whereas lavf's Makefile has a corresponding SHLIBOBJS-$(CONFIG_MXF_MUXER) += golomb_tab.o. E.g. in case the MXF muxer is the only component needing these tables only libavformat.so will contain them for shared builds; currently libavcodec.so does so, too. (There is currently a CONFIG_EXTRA group for golomb. But actually one would need two groups (golomb_avcodec and golomb_avformat) in order to know when and where to include these tables. Therefore this commit uses a Makefile-based approach for this and stops using these groups for the users in libavformat.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* ffbuild: Avoid using the --preprocessor argument to windresMartin Storsjö2021-06-18
| | | | | | | | | | | | | | | | | | | Instead use --preprocessor-arg; in binutils 2.36, the --preprocessor flag was changed so that it no longer accepts a string containing multiple arguments, but the whole --preprocessor argument is treated as the path to the preprocessor executable (where the path can contain spaces). It's currently unclear whether this behaviour will stay or if it is going to be reverted in the future, see discussion at [1]. Just to be safe, avoid using the --preprocessor argument. Don't redeclare the full preprocessing command, but just add the $(CC_DEPFLAGS) options. Based on a patch by Kyle Schwartz.

* ffbuild/common: Make deletion of templates possibleAndreas Rheinhardt2021-02-07
| | | | | | | | | | If a target to be built includes a template file, the target's .d file includes the template file as a prerequisite; if the code were changed so that the template file no longer exists, one would get an error from make that it has no rule for the template file target. Therefore add a dummy rule for template files to make deleting them possible. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* ffbuild: Refine MIPS handlingJiaxun Yang2020-07-23
| | | | | | | | | | | | | | | | To enable runtime detection for MIPS, we need to refine ffbuild part to support buildding these feature together. Firstly, we fixed configure, let it probe native ability of toolchain to decide wether a feature can to be enabled, also clearly marked the conflictions between loongson2 & loongson3 and Release 6 & rest. Secondly, we compile MMI and MSA C sources with their own flags to ensure their flags won't pollute the whole program and generate illegal code.

* build: add support for building CUDA files with clangRodger Combs2019-08-04
| | | | | | | | | | | | | | | | 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. Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>
