* configure: Group math functions into a separate variableDiego Biurrun2012-10-20
| | | | This avoids some duplication when listing and testing for the functions.
* configure: Disable Snow decoder and encoder by defaultDiego Biurrun2012-10-19
| | | | Snow has serious unfixed bugs and no real-world use.

* 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>
* configure: Split out msvc as a separate target OSMartin Storsjö2012-10-18
| | | | | | | | | | The name mingw32 as target OS is both misleading, and very little of the target OS specific settings actually match. Since the target OS default is set based on uname, the default (which on MSYS is set to mingw) is overridden by --toolchain=msvc. Signed-off-by: Martin Storsjö <martin@martin.st>

* configure: Adjust the xgetbv instrinsic checkMartin Storsjö2012-09-10
| | | | | | | | | | | | The 64 bit cl.exe version 16.00.30319.01 crashes with an internal compiler error on the current check (and thus deduces it isn't supported, even if the actual usage in libavuil/x86/cpu.c works fine), but by assigning the value from the intrinsic to a variable, or returning it, it works fine. This error is fixed in cl.exe version 16.00.40219.01. Signed-off-by: Martin Storsjö <martin@martin.st>

* configure: Don't try to enable the log2 function on msvcrtMartin Storsjö2012-09-10
| | | | | | | | | | | | Some msvcrt versions (the static 64 bit libc in MSVC 10) have a log2 function, but there is no declaration for it in the headers. Therefore, the normal configure check might find it, but it can fail during build or at runtime, depending on whether implicit function declarations are an error or not. Therefore simply ignore this function on this platform. Signed-off-by: Martin Storsjö <martin@martin.st>
