According to
https://cmake.org/cmake/help/v3.26/variable/CMAKE_LANG_COMPILER_ID.html
there's at least "Clang" (plain LLVM clang), "AppleClang", "ARMClang",
"FujitsuClang", "XLClang" and "IBMClang" (both of which are variations
of the clang/llvm-based IBM XL compiler).
This should detect all of them (I hope they all behave close enough
to normal clang to work..)
There's also "IntelLLVM", but I have no idea if that's based on Clang
or does its own thing based on LLVM.. I also doubt dhewm3 will ever
be built with any other clang-derivate than "Clang" and "AppleClang" :-p
fixes#510
in the "Work around false positive GCC -W(maybe-)uninitialized warnings"
commit I changed that code.. but my change made it nonsensical,
of course we must get oldBounds before calling the callback which
changes the bounds, otherwise comparing the "oldbounds" with the
current bounds just compares them with themselves..
afxv_w32.h (apparently included indirectly viw edit_gui_common.h)
complained that windows.h (included indirectly via DebuggerServer.h
-> platform.h) was included first, apparently that's not allowed..
this was broken by the recent "fix mingw build" commit; now hopefully
both work (MinGW doesn't support building the tools, because they need MFC
which only works with MSVC)
The HD version of the "Birdman" Hellknight model crashed the game,
because on Linux it triggered the 600KB _alloca() assertion and on
Windows (that didn't have such an assertion up to this commit) it
overflowed the stack.
Thde default stacksize on Windows is 1MB, increasing that to 8MB fixes the
problem (in Doom3 1.3.1 it was 4MB).
I also implemented the _alloca() size check assertion for Windows, and
increased the allowed size to 2MB (so it can be safely called multiple
times per function)

<intrin.h>, included by SDL_cpuinfo.h via SDL.h, defines strcmp.
If the idlib/Str.h `#define strcmp idStr::Cmp` hack is visible when
that file is parsed, there's a compiler error (because strcmp in
intrin.h is replaced with idStr::Cmp then).
So I reorderedd includes a bit until it compiled again..
this was so broken, I think if anyone ever tried to use __DATE__ or
__TIME__ it must've crashed, either from free(curtime) (which was the
return value of ctime()) or from things like token[7] = NULL when token
was a pointer (to a single element!).
I think it could work now.
Also fixed potential memory leaks in cases that don't "return" anything
or, in the case of AF.cpp, at least comment on them
I think this fixes most of the remaining "interesting" GCC 12 on Linux
warnings, except for some in idParser::ExpandBuiltinDefine() that I'll
fix in the next commit
For some reason MSVCs integrated CMake doesn't set CMAKE_GENERATOR_PLATFORM
so my CPU arch detection magic in CMakeLists.txt didn't work in that case..
Now (when using MSVC) the CPU architecture (D3_ARCH) is set in
neo/sys/platform.h instead.
-DASAN=ON enables the Address Sanitizer (ASan), if supported
-DUBSAN=ON same for Undefined Behavior Sanitizer (UBSan)
-DFORCE_COLORED_OUTPUT=ON forces GCC or Clang to use colors in their
messages, useful when building with ninja
All three options default to OFF (though when building with make in a
suitable terminal, GCC and clang automatically use colors)
Also modified the cmake_minimum_required() line to shut up deprecation
warnings (though TBH I have no idea if this really still works with
CMake 2.6)
Commit 3c01757d27 introduced scaling down all sounds to prevent too
many loud-ish sounds from making OpenAL scale the overall volume down.
The problem is that before this change, many sounds had a volume > 1.0,
but vastly different: e.g. player_machinegun_fire was 5.039685 (14dB)
and player_chaingun_fire was 1.414214 (3dB).
But in the end, all volumes were clamped to 1.0 before setting AL_GAIN
(because AL_GAIN only supports values between 0 and 1 by default), so
the machinegun and chaingun had the same volume after all.
When scaling those down to 1/3 of the original volume, some sounds that
used to have a volume of >= 1.0 (=> AL_GAIN set to 1.0) had a volume
lower than 1.0, so they suddenly the chaingun sounded quiter than
the machinegun. While theoretically this is more correct than before
(after all, the sound shader of player_chaingun_fire set a much lower
volume than that of player_machinegun_fire), it doesn't sound like it
used to (even with the old software sound backend!).
Clamping to 1.0 *before* scaling to 1/3 should restore the old behavior
(of all sounds with volume > 1.0 before clamping using the same AL_GAIN)
while still avoiding the issue of having OpenAL (Soft) scale down the
overall volume when shooting a metal wall with the shotgun.
Unsurprisingly the same problem (inconsistent weapon volumes due to
incorrect sound shaders setting the volume way to high and thus relying
on being clamped to 1.0) that occurred with my volume *= 0.333 hack
also happens when reducing the global volume.
So apply that global volume scale *after* clamping to 1.0

Some entities wrote the handle from gameRenderWorld->AddLightDef()
into savegames and reused it after restoring it.
That's a bad idea, because at that point the handle most likely belongs
to something else (likely some idLight). The most visible issue this
can create is that the flashlight may not work correctly after loading
a savegame with flashlight on, when it happens to alias a light that's
updated each frame to (mostly) being off..
The correct way to handle this (THAT FOR SOME REASON WAS ALREADY
IMPLEMENTED IN D3XP BUT NOT THE BASE GAME - WHY?!) is to get a fresh
handle with AddLightDef() when restoring a savegame - unless the handle
was -1, which means that the light didn't exist when saving.
fixes#495
Some level scripts in d3xp (erebus4, erebus4, phobos2) use
$entity.startSoundShader( "", SND_CHANNEL_BODY );
(or whatever channel) to stop the sound currently playing there.
With s_playDefaultSound 1 that results in a beep..
Added a special case to that event implementation to call StopSound()
instead when the soundName is "" (or NULL)
the problem was a double-free on files, because USE_COLLADA is not defined.
I'm not even sure why this USE_COLLADA code exists, as we don't have any
real collada support code anywhere..
.. by surrounding it with newlines.
This warning is shown when trying to start a mod without its game dll
(because the user has forgotten to unpack the mod dll archive, or
because it's a mod that doesn't have its own dll).
Surrounding it with empty lines hopefully makes it easier for users
to figure out what went wrong when they look at the log.
When selecting a light in the Radiant (builtin Windows-only level editor)
and pressing `j`, the light editor opened (as expected) but said that
no entity was selected.
That was because com_editorActive was false, most probably because of
e8a1eb8b Fix mouse remaining ungrabbed when running map from Radiant
which sets com_editorActive to false (via com->ActivateTool(false)) if
the Radiant window loses focus, which should be the case when opening
the light editor window.
`com_editors & EDITOR_RADIANT` is != 0 as long as the radiant is
running, no matter which window currently has focus, so it works better.
and add entry to changelog about absolute mouse input etc - this change
was already in RC1 but I forgot to mention it..
and fixed comments for GAME_NAME and ENGINE_VERSION (nowadays dhewm3
uses ENGINE_VERSION for the window title)
It happened a lot more since
504b572a Update sounds at ~60Hz instead of ~10Hz, fixes#141
(because then MixLoop() is more likely to be called in the narrow
timeframe this can happen during level load) but could happen before.
So far I only observed it when starting a new game in Classic Doom 3.
See comment in the change and #461 for more information.
Hoping that Team Future eventually fulfills their promise of releasing
the source of the highly praised Phobos mod, I'm adding it to the list.
Currently this is not very useful, but when (if) the phobos source
becomes available I at least won't have to do a new dhewm3 release to
support it (but only provide tfphobos.dll/.so/.dylib).
by adding special cases for them that set `fs_game_base d3xp`.
Unfortunately there is no more generic way to do this, as mods have
no way to tell the engine if they need fs_game_base.
The assertion that triggered was "assert(iconvDesc == (SDL_iconv_t)-1);"
in Sys_InitInput() - because when loading a mod the window is recreated,
calling Com_ReloadEngine_f() -> idCommonLocal::InitGame()
-> idCommonLocal::InitRenderSystem() -> idCommonLocal::InitOpenGL()
-> R_InitOpenGL() -> Sys_InitInput()
Before that Com_ReloadEngine_f() calls commonLocal.ShutdownGame( true );
which calls the equivalent Shutdown() functions - except so far no one
called Sys_ShutdownInput() (which closes iconvDesc and resets it to -1).
Fixed that by making idRenderSystemLocal::ShutdownOpenGL() call it.
In the savegame from that bugreport, "monster_zsec_shotgun_12" was
lying dead pretty much at its spawn point.
script/map_alphalabs4.script moves those "ride_of_death" platforms
around, and at the end of a cycle teleports "ride_of_death*_parent" back
to its starting position - and the "ride_of_death*" bound to it, which
is a pushing mover, just gets dragged along by the physics code and thus
can collide with that zombie cadaver, which then tries to push it along,
causing that assertion in TestHugeTranslation().
This is a map bug - Doom3 even prints a warning:
WARNING: script/map_alphalabs4.script(722): Thread
'map_alphalabs4::RideOfDeathPath': teleported 'ride_of_death2_parent'
which has the pushing mover 'ride_of_death2' bound to it
So I just disable that assertion for this specific case..
Also moved the assertion behind the corresponding warning, so that gets
printed before the assertion kills the game..
Also a small change to CMakeLists.txt that should make enabling
LINUX_RELEASE_BINS after CMake has already been run without it work
For some reason Wayland thought it would be clever to be the only
windowing system that (non-optionally) uses the alpha chan of the
window's default OpenGL framebuffer for window transparency.
This always caused glitches with dhewm3, as Doom3 uses that alpha-chan
for blending tricks (with GL_DST_ALPHA) - especially visible in the main
menu or when the flashlight is on.
So far the workaround has been r_waylandcompat which requests an OpenGL
context/visual without alpha chan (0 alpha bits), but that also causes
glitches.
There's an EGL extension that's supposed to fix this issue
(EGL_EXT_present_opaque), and newer SDL2 versions use it (when using
the wayland backend) - but unfortunately the Mesa implementation is
broken (seems to provide a visual without alpha channel even if one was
requested), see https://gitlab.freedesktop.org/mesa/mesa/-/issues/5886
and https://github.com/libsdl-org/SDL/pull/4306#issuecomment-1014770600
for the corresponding SDL2 discussion
To work around this issue, dhewm3 now disables the use of that EGL
extension and (optionally) makes sure the alpha channel is opaque at
the end of the frame.
This behavior is controlled with the r_fillWindowAlphaChan CVar:
If it's 1, this always is done (regardless if wayland is used or not),
if it's 0 it's not done (even on wayland),
if it's -1 (the default) it's only done if the SDL "video driver" is
wayland (this could be easily enhanced later in case other windowing
systems have the same issue)
r_waylandcompat has been removed (it never worked properly anyway),
so now the window always has an alpha chan
so if someone configured 16x AA on a system that doesn't support it
(like when using AMDs open source driver), 8x will be tried before
falling back to a 640x480 window with no AA at all.
(and then it'll try 4x and then 2x and then no AA at all, and only then
reducing color depth will start, and even later it'll fall back to
a small 640x480 window)
