Description

Fatal error when compiling on Raspbian running on Raspberry Pi 4 4Gb.

Expected behavior

Compiles successfully

Actual behavior

CC gfx/drivers/dispmanx_gfx.c
gfx/drivers/dispmanx_gfx.c:17:10: fatal error: bcm_host.h: No such file or directory
#include <bcm_host.h>
^~~~~~~~~~~~
compilation terminated.
make: *** [Makefile:213: obj-unix/release/gfx/drivers/dispmanx_gfx.o] Error 1

make -j4 output available on PasteBin

Steps to reproduce the bug

1. git clone https://github.com/libretro/RetroArch.git
2. sudo apt-get install build-essential libxkbcommon-dev zlib1g-dev libfreetype6-dev libegl1-mesa-dev libgles2-mesa-dev libgbm-dev libavcodec-dev libsdl2-dev libsdl-image1.2-dev libxml2-dev yasm libavformat-dev libavdevice-dev libswresample-dev libavresample-dev libswscale-dev libv4l-dev libgl*-mesa-dev
3. CFLAGS='-mfpu=neon' ./configure --enable-alsa --enable-udev --enable-floathard --enable-neon --enable-dispmanx --disable-opengl1 --disable-videocore --enable-opengles --enable-opengles3
4. make -j4

Version/Commit

You can find this information under Information/System Information

• RetroArch: 666ebb0 and on v1.8.1 bfdc8e6 with slightly different error

Environment information

• OS: Raspbian on Raspberry Pi 4 4Gb. Linux raspberrypi 4.19.81-v7l+ Retroarch-Wii #1276 SMP Fri Nov 1 14:23:48 GMT 2019 armv7l GNU/Linux]
• Compiler: gcc (Raspbian 8.3.0-6+rpi1) 8.3.0

Solution to get further but to a different error:

Add -I/opt/vc/include to CFLAGS:
CFLAGS='-mfpu=neon -I/opt/vc/include' ./configure --enable-alsa --enable-udev --enable-floathard --enable-neon --enable-dispmanx --disable-opengl1 --disable-videocore --enable-opengles --enable-opengles3

GIves a different error:

Yes I have, didn't work. running rpi-update didn't work either.

I managed to get further in the compile process by adding -I/opt/vc/include to CFLAGS but the compile still dies with error:

CC led/drivers/led_rpi.c
LD retroarch
/usr/bin/ld: obj-unix/release/gfx/drivers/dispmanx_gfx.o: undefined reference to symbol 'vc_dispmanx_display_close'

I was able to compile without dispmanx:

CFLAGS='-mfpu=neon' ./configure --enable-alsa --enable-udev --enable-floathard --enable-neon --disable-opengl1 --disable-videocore --enable-opengles --enable-opengles3 --disable-dispmanx

Anyone know why dispmanx is giving me issues?

Pi4 does not support or use dispmanx and proprietary (legacy) firmware based GL* drivers (those from /opt/vc).
For pi4 standard opensource mesa drivers should be used over drm/kms, x11 or wayland.

Configure scripts should nowadays handle RPi4 without extra options, guide also available: https://docs.libretro.com/guides/rpi/
I believe this one can be closed.
