| | | | This allows overriding the value from outside of the file.

| | | | | | | Unlike YASM, NASM only looks for include files in the current directory, not in the directory that included files reside in. Signed-off-by: Diego Biurrun <diego@biurrun.de>

| | | | | | This reverts commit def8c94699877d015154a03d43e2b8f479cd89a0. After the major bump this is no longer necessary.

* lavu: bump major to 52Anton Khirnov2012-10-23
| | | | | | In addition to the recent tables mess, the AVOption defaults behavior changed, so an old lavc used with a new lavu will get completely messed up defaults.

* avutil: Add a copy of ff_sqrt_tab back into avutil to restore ABI compatibilityMartin Storsjö2012-10-20
| | | | | | | | | | | | Earlier versions of for instance of libavcodec expect this symbol to be present in libavutil. This commit can be reverted after the next major bump. New shared builds of avcodec will link to the internal copy of the table within that library, so those builds won't rely on this table being present in avutil any longer either.

| | | | | | | These tables are used for instance by older versions of libavcodec and need to remain visible until the next SONAME bump. Signed-off-by: Martin Storsjö <martin@martin.st>
* avutil: remove inline av_log2 from public APIMans Rullgard2012-10-20
| | | | | | | | This removes inline av_log2 and av_log2_16bit from the public API, instead exporting them as regular functions. In-tree code still gets the inline and otherwise optimised variants. Signed-off-by: Mans Rullgard <mans@mansr.com>

* Add support for building shared libraries with MSVCMartin Storsjö2012-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This requires the makedef perl script by Derek, from the c89-to-c99 repo. That scripts produces a .def file, listing the symbols to be exported, based on the gcc version scripts and the built object files. To properly load non-function symbols from DLL files, the data symbol declarations need to have the attribute __declspec(dllimport) when building the calling code. (On mingw, the linker can fix this up automatically, which is why it has not been an issue so far. If this attribute is omitted, linking actually succeeds, but reads from the table will not produce the desired results at runtime.) MSVC seems to manage to link DLLs (and run properly) even if this attribute is present while building the library itself (which normally isn't recommended) - other object files in the same library manage to link to the symbol (with a small warning at link time, like "warning LNK4049: locally defined symbol _avpriv_mpa_bitrate_tab imported" - it doesn't seem to be possible to squelch this warning), and the definition of the tables themselves produce a warning that can be squelched ("warning C4273: 'avpriv_mpa_bitrate_tab' : inconsistent dll linkage, see previous definition of 'avpriv_mpa_bitrate_tab'). In this setup, mingw isn't able to link object files that refer to data symbols with __declspec(dllimport) without those symbols actually being linked via a DLL (linking avcodec.dll ends up with errors like "undefined reference to `__imp__avpriv_mpa_freq_tab'"). The dllimport declspec isn't needed at all in mingw, so we simply choose not to declare it for other compilers than MSVC that requires it. (If ICL support later requires it, the condition can be extended later to include both of them.) This also implies that code that is built to link to a certain library as a DLL can't link to the same library as a static library. Therefore, we only allow building either static or shared but not both at the same time. (That is, static libraries as such can be, and actually are, built - this is used for linking the test tools to internal symbols in the libraries - but e.g. libavformat built to link to libavcodec as a DLL cannot link statically to libavcodec.) Also, linking to DLLs is slightly different from linking to shared libraries on other platforms. DLLs use a thing called import libraries, which is basically a stub library allowing the linker to know which symbols exist in the DLL and what name the DLL will have at runtime. In mingw/gcc, the import library is usually named libfoo.dll.a, which goes next to a static library named libfoo.a. This allows gcc to pick the dynamic one, if available, from the normal -lfoo switches, just as it does for libfoo.a vs libfoo.so on Unix. On MSVC however, you need to literally specify the name of the import library instead of the static library. Signed-off-by: Martin Storsjö <martin@martin.st>
