Compilation failure on Raspberry Pi 4: SDLGLGraphicsContext.cpp:90:37: error: 'XOpenDisplay' was not declared in this scope #12346

Closed neilmunday closed 5 years ago

neilmunday commented 5 years ago

What happens?

Compilation failure under Arch Linux on Raspberry Pi 4 with SDL 2.0.10.

What should happen?

Successful compilation.

What hardware, operating system, and PPSSPP version? On desktop, GPU matters for graphical issues.

Raspberry Pi4, Arch Linux, PPSSPPP git clone.

Compilation error:

unknownbrackets commented 5 years ago

How do you configure? It seems like it's not being compiled with X?

-[Unknown]

neilmunday commented 5 years ago

Correct, I am trying to build PPSSPP without X. I have done this in the past for the Raspberry Pi 2 and 3.

Here are the commands I am using to build PPSSPP:

git clone git://github.com/hrydgard/ppsspp
git submodule init
git submodule update
./linux_rpi.sh
mkdir build
cd build
cmake -D SDL2_LIBRARY:PATH=/opt/sdl2/default/lib/libSDL2.so \
-D SDL2_INCLUDE_DIR:PATH=/opt/sdl2/default/include/SDL2 \
-D CMAKE_INSTALL_PREFIX:PATH=/opt/ppsspp \
-D CMAKE_TOOLCHAIN_FILE=../cmake/Toolchains/raspberry.armv7.cmake \
-D USING_X11_VULKAN=0 \
..

I am also using the vc4-fkms-v3d dtoverlay for the Raspberry Pi 4 in /boot/config.txt.

SDL2 2.0.10 was configured with the following configure flags:

./configure --prefix=/opt/sdl2/default --enable-assertions=disabled --disable-video-opengl --disable-video-x11 --disable-pulseaudio --disable-esd --enable-video-opengles --enable-libudev --disable-video-rpi --enable-video-kmsdrm

unknownbrackets commented 5 years ago

With the Pi 4, apparently it now works to use X and get hardware acceleration (so I understand, haven't tried a Pi 4.)

As such, USING_FBDEV is not forced on for Pi 4: https://github.com/hrydgard/ppsspp/blob/6a1676413ee8bdbb53e0c133e02cf74a8950a13a/cmake/Toolchains/raspberry.armv7.cmake#L35-L39

If you want fbdev still on Pi 4, just pass -D USING_FBDEV=ON to cmake (you can safely pass this for Pi 2/3/etc. as well.)

Thanks for the info. I'll give it go over the next few days and feedback.

Although PPSSPP now compiles, it fails at run time:

It looks like it might be trying to use the /opt/vc libraries which don't work on the Raspberry Pi 4.

LunaMoo commented 5 years ago

See #12388, closing since it compiles and the runtime issue was reported a new driver problem.

unknownbrackets commented 5 years ago

It would be interesting to know if other GL apps using fbdev still work fine. We're not really doing anything strange.

-[Unknown]

neilmunday commented 5 years ago

I've compiled RetroArch and Mupen64Plus (standalone) and they both work for me. Retroarch is using OpenGL/KMS and Mupen64Plus is using GLES and SDL2 (built with kms also). I think PPSSPP is picking up the GLES libraries under /opt/vc which aren't supported on the Raspberry Pi 4. I'll try telling PPSSPP to use the GLES libraries under /usr/lib instead.

unknownbrackets commented 5 years ago

If it works to move set(CMAKE_EXE_LINKER_FLAGS "-L/opt/vc/lib" CACHE STRING "" FORCE) inside the if to, that seems reasonable.

People had reported it working on Pi 4, so IO wonder what changed. Unfortunately, I don't have a device to test with.

neilmunday commented 5 years ago

Here's the cmake file I used with my latest attempt:

set(ARCH_FLAGS "-mfpu=neon -mtune=cortex-a72 -march=armv8-a -mfloat-abi=hard")
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${ARCH_FLAGS}"  CACHE STRING "" FORCE)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${ARCH_FLAGS}" CACHE STRING "" FORCE)
set(CMAKE_ASM_FLAGS "${CMAKE_ASM_FLAGS} ${ARCH_FLAGS}" CACHE STRING "" FORCE)
set(OPENGL_LIBRARIES /usr/lib/libGLESv2.so)
set(USING_GLES2 ON)
set(ARMV7 ON)
set(USE_WAYLAND_WSI OFF)
set(USING_FBDEV ON)
set(USING_X11_VULKAN OFF)

Is there any workaround for this?

neilmunday commented 5 years ago

I've not found a way to make it work sadly. My next approach was going to be to install an X desktop, but I was hoping to avoid this.

unknownbrackets commented 4 years ago

Is it possible this is related to #12474?

-[Unknown]

neilmunday commented 4 years ago

Apologies for the delay in replying, the Raspberry Pi 4 I was using was on loan from a friend. I now however, have my own Raspberry Pi 4 so I've spent some more time trying to get PPSPP working under Arch Linux (as tried above).

The original issue remains sadly. I have also tried installing an X windows desktop (Xfce) and I get these errors instead:

That looks exactly like #12474.

See here specifically: https://github.com/hrydgard/ppsspp/issues/12474#issuecomment-569979614 And the Mesa issue: https://gitlab.freedesktop.org/mesa/mesa/issues/1976#note_285659

Ok, thanks.

Is there anything I can do to help resolve or debug the issue further for you?

unknownbrackets commented 4 years ago

Well, it sounds like the mesa team was wanting someone to set some breakpoints and find out if somehow we're asking for the same surface to be used with multiple EGL instances, because that's apparently the commit it stopped working on - only on pi4, though.

I've now managed to get PPSSPP to work without requiring an X11 desktop under Arch Linux on the Raspberry Pi 4.

Mesa upgraded to version 20.0.6-2. SDL2 upgraded to 2.0.12

Used the following cmake args:

-DARMV7=ON -DUSING_EGL=OFF -DUSING_GLES2=ON -DUSING_X11_VULKAN=OFF -DUSE_WAYLAND_WSI=OFF -DUSING_FBDEV=ON -DUSING_QT_UI='OFF' -DUSE_FFMPEG=yes -DUSE_SYSTEM_FFMPEG=yes
