Build is linking against X11 even with NO_X11=1 #14336
Description
MAME version
System information
Raspberry Pi 5 8GB running Gentoo
Linux 6.12.44-v8+ #1902 SMP PREEMPT Fri Aug 29 15:19:33 BST 2025 aarch64 GNU/Linux
INI configuration details
Emulated system/software
No response
Incorrect behaviour
Using the following build parameters:
make \
OSD=sdl \
USE_WAYLAND=1 \
NO_X11=1 \
USE_XINPUT=0 \
USE_TAPTUN=0 \
USE_PCAP=0 \
NO_USE_PULSEAUDIO=1 \
NO_USE_PORTAUDIO=1 \
USE_QTDEBUG=0 \
REGENIE=1
Linking fails while looking for references to XPending, even though NO_X11=1 is used:

Expected behaviour
Mame should link successfully.

Additional details
I have even tried building libsdl2 with X11 support enabled (which I shouldn't have to), and it made no difference.
# equery u libsdl2
[ Legend : U - final flag setting for installation]
[ : I - package is installed with flag ]
[ Colors : set, unset ]
* Found these USE flags for media-libs/libsdl2-2.32.8:
U I
+ + X : Add support for X11
+ + alsa : Add support for media-libs/alsa-lib (Advanced Linux Sound Architecture)
- - dbus : Enable dbus support for anything that needs it (gpsd, gnomemeeting, etc)
- - doc : Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
- - fcitx : Enable support for app-i18n/fcitx
- - gles1 : include OpenGL ES 1.0 support
+ + gles2 : Enable GLES 2.0 (OpenGL for Embedded Systems) support (independently of full OpenGL, see also: gles2-only)
+ + haptic : Enable the haptic (force feedback) subsystem
- - ibus : Enable support for app-i18n/ibus
- - jack : Add support for the JACK Audio Connection Kit
+ + joystick : Control joystick support (disable at your own risk)
+ + kms : Build the KMSDRM video driver
+ + libsamplerate : Build with support for converting sample rates using libsamplerate
- - nas : Add support for network audio sound
+ + opengl : Add support for OpenGL (3D graphics)
- - oss : Add support for OSS (Open Sound System)
- - pipewire : Enable support for the media-video/pipewire audio backend
- - pulseaudio : Add sound server support via media-libs/libpulse (may be PulseAudio or PipeWire)
- - sndio : Enable support for the media-sound/sndio backend
+ + sound : Control audio support (disable at your own risk)
- - static-libs : Build static versions of dynamic libraries as well
- - test : Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled
independently)
+ + udev : Enable virtual/udev integration (device discovery, power and storage device support, etc)
+ + video : Control video support (disable at your own risk)
+ + vulkan : Add support for 3D graphics and computing via the Vulkan cross-platform API
+ + wayland : Enable dev-libs/wayland backend
- - xscreensaver : Add support for XScreenSaver extension
If I am doing anything wrong, please let me know, but I do not believe this behavior is correct. Thanks!
