And troll Microsoft slightly while we're at it. But is it trolling if
it's the truth?
The level of C99 support in MSVC is probably a bit better than most
people think, but it's by far not adequate. We need a bit of either C11
or GNU extensions too, and rely on some MinGW helpers (that look like
they're provided by MS, except they're not).
- Don't recommend libdvdnav, since DVD support isn't compiled by default
anymore.
- Take advantage of the new $MINGW_PACKAGE_PREFIX and $MSYSTEM_PREFIX
variables to make the build commands independent from the mingw-w64
build environment being used.
- Invoke /usr/bin/python3 directly, since I've heard some packages have
started to depend on mingw-w64 versions of Python, but our build
scripts only work with the MSYS2 version.
- Reword the MSYS2 install instructions to try to prevent common errors.
This fixes waf setting the wrong LIBDIR for DEST_OS=win32 in
waflib/Tools/c_config.py:get_cc_version()
Any scripts assuming the implib and pkgconfig are in the wrong
place should be changed to move the .dll instead.
* Use the update-core command
* Add --check-c-compiler=gcc to be safe
* Add warning about potential pitfalls of adding C:\msys2\mingw64\bin to %PATH%
* Recommend winpty
* Add note about ANGLE
Both mpv and ffmpeg have their own internal pthreads wrappers. The mpv
one has been recently enabled by default as well. (It didn't work on XP,
but we dropped XP support.)
libwaio was added due to the complete inability to cancel synchronous
I/O cleanly using the public Windows API in Windows XP. Even calling
TerminateThread on the thread performing I/O was a bad solution, because
the TerminateThread function in XP would leak the thread's stack.
In Vista and up, however, this is no longer a problem. CancelIoEx can
cancel synchronous I/O running on other threads, allowing the thread to
exit cleanly, so replace libwaio usage with native Vista API functions.
It should be noted that this change also removes the hack added in
8a27025 for preventing a deadlock that only seemed to happen in Windows
XP. KB2009703 says that Vista and up are not affected by this, due to a
change in the implementation of GetFileType, so the hack should not be
needed anymore.
mpv can be built natively on a Windows machine using MSYS2. Add detailed
instructions on how to build and merge them with the existing
instructions for cross-compilation.
