* Makefile: Prompt for reconfigure on lavc/hwaccels.h modificationAndreas Rheinhardt2022-07-011-0/+1
| | | | | | | | | | | | | | | | Adding a new AVHWAccel also adds a new CONFIG variable for it and said config variables are typically used to calculate the size of stack arrays. In such a context, an undefined CONFIG variable does not evaluate to zero; instead it leads to a compilation failure. Therefore treat this file like the other files containing lists of configurable components and prompt for reconfiguration if it is modified. (E.g. a44fba0b5b3b4090f9238751736198ddd1f0f1d5 led to compilation failures for me.) Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* Makefile: avoid cp-ing over existing executable filesrcombs2022-06-011-0/+1
| | | | | | | | | On macOS, code-signing information for executables (including those signed automatically by the linker) is cached by the system on a per-inode basis. The cp(1) tool will truncate and overwrite an existing file if present, so we need to delete it first to avoid strange crashes.

* Makefile: Redo duplicating object files in shared buildsAndreas Rheinhardt2022-01-041-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * build: Fine-grained link-time dependency settingsDiego Biurrun2017-03-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Previously, all link-time dependencies were added for all libraries, resulting in bogus link-time dependencies since not all dependencies are shared across libraries. Also, in some cases like libavutil, not all dependencies were taken into account, resulting in some cases of underlinking. To address all this mess a machinery is added for tracking which dependency belongs to which library component and then leveraged to determine correct dependencies for all individual libraries.
