![Luca Barbato](/assets/img/avatar_default.png)
Recent versions of macOS provide more POSIX API (in particular, clock_gettime) than previous versions and recent Apple toolchains provide all that API, even when targeting older releases without said API. Disallow linking to functions which might not be available at runtime. To actually have an effect, either add --extra-cflags="-mmacosx-version-min=10.11" (or any other version prior to 10.12) or set MACOSX_DEPLOYMENT_TARGET=10.11 when running configure. As a workaround for libav versions without this fix, one can also add --extra-cflags="-mmacosx-version-min=10.11 -Werror=partial-availability" while running configure. The -no_weak_imports flag is new in Xcode 8; in Xcode 7 it is not supported. This is not an issue since Xcode 7 only ships with the 10.11 macOS SDK, which lacks clock_gettime.

External library support:
|
|
|
|
Using any of the following switches will allow Libav to link to the
|
|
corresponding external library. All the components depending on that library
|
|
will become enabled, if all their other dependencies are met and they are not
|
|
explicitly disabled. E.g. --enable-libwavpack will enable linking to
|
|
libwavpack and allow the libwavpack encoder to be built, unless it is
|
|
specifically disabled with --disable-encoder=libwavpack.
|
|
|
|
Note that only the system libraries are auto-detected. All the other external
|
|
libraries must be explicitly enabled.
|
|
|
|
Also note that the following help text describes the purpose of the libraries
|
|
themselves, not all their features will necessarily be usable by Libav.
