If multiple mingw toolchains are installed, the Makefile set CC to all
present gcc executables. Pick only the first one instead of passing the
others as arguments.
"CC: /usr/bin/i686-w64-mingw32-gcc /usr/bin/i686-pc-mingw32-gcc"
Server/client VoIP protocol is handled by adding new cvars
cl_voipProtocol and sv_voipProtocol, sv_voip and cl_voip
are used to auto set/clear them. All users need to touch
are cl/sv_voip as 0 or 1 just like before.
Old Speex VoIP packets in demos are skipped.
New VoIP packets are skipped in demos if sv_voipProtocol
doesn't match cl_voipProtocol.
Notable difference between usage of speex and opus codecs,
when using Speex client would be sent 80ms at a time.
Using Opus, 60ms is sent at a time. This was changed because
the Opus codec supports encoding up to 60ms at a time.
(Simpler to send only one codec frame in a packet.)
If TERM is not set (which can happen in autobuilders and other
batch environments), or if tput cannot determine the number of
columns for some other reason, then it can fail and not produce
any output. Prior to this change, that would result in passing
field width -4 to fmt, which is an error and causes fmt to
produce no output.
GNU platforms (Linux, kFreeBSD, Hurd) have endian.h to determine
endianness, so all architectures except x86_64 are in fact treated
identically, except that their ARCH_STRING is different.
The ARCH_STRING must always be identical to the ARCH from the Makefile,
otherwise the engine will not find its cgame, game and ui plugins
under their expected names and startup will fail. If we pass it in
from the Makefile, then an identical value is guaranteed, and we can
get rid of an increasingly long list of defined(__some_cpu__) tests.
The one remaining quirk is that we test __x86_64__ to determine
whether to define idx64; I've kept that, but separated it from
the ARCH_STRING.
On non-Linux platforms we only support a few architectures anyway,
so keeping the list up to date is less of a burden; *BSD porters
could probably use the same technique to get support for lots of
architectures with little effort, but I have not done that here,
because I cannot test it.
Windows must continue to support preprocessor-based architecture tests
in any case, so that the MSVC solutions (which do not use the Makefile)
can continue to work. However, Windows only runs on a few CPU families,
so this shouldn't be a significant burden in practice.
When cross-compiling, the tools are compiled for the build architecture
(COMPILE_PLATFORM, COMPILE_ARCH) rather than the host architecture
(PLATFORM, ARCH), so define ARCH_STRING to COMPILE_ARCH on a GNU
COMPILE_PLATFORM.
The ARCH in the Makefile must match the ARCH_STRING in q_platform.h;
otherwise, ioquake3 will install (for instance) uiARCH.so but look for
uiARCH_STRING.so, which isn't going to go well (particularly for
the modular renderer).
Like i386, but unlike most (all?) other Linux platforms, uname -m on
32-bit ARM machines can have various results starting with "arm",
depending on the specific CPU version (e.g. Raspberry Pi is armv6l,
RPi2 is armv7l). Again similar to the x86 family,
it's appropriate for them to share an architecture suffix;
q_platform.h has traditionally used "arm" so let's use that.
64-bit ARM makes a clean break from this, much like 64-bit x86 does:
uname -m produces a string not starting with arm (specifically
"aarch64"), and gcc predefines __aarch64__ instead of __arm__.
As a result, it is unaffected by this change.
Based on Thilo's Elite Force patch for ioq3.
Updated Makefile changes. Left out in-tree win32 lib support.
Striped trailing whitespace from snd_codec_mp3.c.
Changed two #if USE_CODEC_MP3 to use #ifdef.
