Only 64-bit windows is tested, and there are still various failures, but
QF is limping along in windows again.
nq-sdl works for sw, and sw32, gl and glsl are mostly black (but not
entirely for gl?), vulkan is not supported with sdl.
nq-win works for sw and sw32, and sort of for vulkan (very dark and
upside-down?). gl and glsl complain about vid mode,
qw-client-[sdl,win] seem to be the same, but something is wrong with the
console (reading keyboard input).
While this caused some trouble for pr_strings and configurable strftime
(evil hacks abound), it's the result of discovering an ancient (from
maybe as early as 2004, definitely before 2012) bug in qwaq's printing
that somehow got past months of trial-by-fire testing (origin understood
thanks to the warning finding it).
QF_PROCESS_NEED_LIST is a better name as for one, building no longer
depends on directories, and the directories were lists anyway, so the
name is more generally applicable.
The static libs are used to build the plugins, but make it easy to use
only those modules needed for tests. Fixes the link error when running
"make check" with non-static plugins.
They take advantage of gcc's vector_size attribute and so only cross,
dot, qmul, qvmul and qrot (create rotation quaternion from two vectors)
are needed at this stage as basic (per-component) math is supported
natively by gcc.
The provided functions work on horizontal (array-of-structs) data, ie a
vec4d_t or vec4f_t represents a single vector, or traditional vector
layout. Vertical layout (struct-of-arrays) does not need any special
functions as the regular math can be used to operate on four vectors at
a time.
Functions are provided for loading a vec4 from a vec3 (4th element set
to 0) and storing a vec4 into a vec3 (discarding the 4th element).
With this, QF will require AVX2 support (needed for vec4d_t). Without
support for doubles, SSE is possible, but may not be worthwhile for
horizontal data.
Fused-multiply-add is NOT used because it alters the results between
unoptimized and optimized code, resulting in -mfma really meaning
-mfast-math-anyway. I really do not want to have to debug issues that
occur only in optimized code.
Shaders can be built as spv files and installed into
$libdir/quakeforge/shaders or as spvc files and compiled into the
engine. Loading supports $builtin/name to access builtin shaders,
$shader/path to access external standard shaders and quake filesystem
access for all other paths.
There's still some cleanup to do, but everything seems to be working
nicely: `make -j` works, `make distcheck` passes. There is probably
plenty of bitrot in the package directories (RPM, debian), though.
The vc project files have been removed since those versions are way out
of date and quakeforge is pretty much dependent on gcc now anyway.
Most of the old Makefile.am files are now Makemodule.am. This should
allow for new Makefile.am files that allow local building (to be added
on an as-needed bases). The current remaining Makefile.am files are for
standalone sub-projects.a
The installable bins are currently built in the top-level build
directory. This may change if the clutter gets to be too much.
While this does make a noticeable difference in build times, the main
reason for the switch was to take care of the growing dependency issues:
now it's possible to build tools for code generation (eg, using qfcc and
ruamoko programs for code-gen).
As well as $prefix/include, of course. This fixes the problem with
external ruamoko builds failing due to keys.h and qfcc's "lockdown" on
system headers.
This fixes the dependency issues between qwaq and ruamoko. qwaq is
actually older than ruamoko. That little language feature test has come
a long way.
However, I'm considering moving to non-recursive make, but...
This paves the way for clean initialization of the Vulkan renderer, and
very much cleans up the older renderer initialization code as gl and sw
are no longer intertwined.
This removes a lot of redundant code from qflight (though it does become
dependent of libQFgamecode *shrug*). The nice thing is qflight now uses the
exact same code to load entities as does the server.
It is suffering some bitrot and I don't feel like fixing it right now, but
it causes problems for people trying to build QF. This should be ok because
it's one of those "if uncertain, say no" things.
The win clients are the native windows (NOT sdl!! *twitch*). Things are
already looking on the up: only three errors in in_win.c. I'm not looking
forward to vid_win.c (ex vid_wgl.c), though.
The ~ gets expanded to CSIDL_LOCAL_APPDATA, $HOME, $USERPROFILE or just
".", whichever succeeds first. The usual location will be:
"C:\windows\profiles\<user>\Local Settings\Application Data".
"." is now the fallback for *nix systems too.
It turns out the apiprefix define is quite new (I didn't realize it at the
time) and I'd rather get FTBFS reports based on configure catching the
error than gcc catching it.
It seems -ffast-math is not necessarily faster, and the errors it causes
may not be worth the gains, but I'm not sure I want to nuke it completely,
so instead disabling the worst offender of it
(-fno-unsafe-math-optimizations) seems to be the best option. qfbsp now
produces identical text output between optimized and unoptimized builds,
and may be slightly faster than before the change (1.9s for start.map vs
2.0s)
