[shenzhuxi]

TO REPRODUCE THE ISSUE, FOLLOW THESE STEPS:

• checkout the main branch (or 0.17.0)
• follow the steps from https://github.com/tangrams/tangram-es/tree/main/platforms/rpi until run "make rpi"
• get the errors as below

EXPECTED RESULT:

There is no problem to build the main branch on Windows 10 with
cmake -S . -B .\build -G "Visual Studio 17 2022" -DCMAKE_TOOLCHAIN_FILE="\scripts\buildsystems\vcpkg.cmake"

ENVIRONMENT:

• Raspberry Pi 3 B+
• Raspbian GNU/Linux 11 (bullseye)
• tangram-es main branch or 0.17.0

OTHER:

It will be also good to add "sudo apt-get install libgles2-mesa-dev" to https://github.com/tangrams/tangram-es/tree/main/platforms/rpi.

I don't think "Visual Studio 16 2019" can be downloaded from https://visualstudio.microsoft.com/downloads/ and it will be good to update https://github.com/tangrams/tangram-es/tree/main/platforms/windows with:

cmake -S . -B .\build -G "Visual Studio 17 2022" -DCMAKE_TOOLCHAIN_FILE="\scripts\buildsystems\vcpkg.cmake"

Thanks for the report. Can you tell me the compiler version that you are using on your Raspberry Pi?

I just finished building on Raspberry with "make linux" by following https://github.com/tangrams/tangram-es/tree/main/platforms/linux and adding "-latomic" to https://github.com/tangrams/tangram-es/blob/main/platforms/linux/config.cmake.

Two variables GLintptr and GLsizeiptr need to be renamed to avoid the name conflicts.

But the performance is quite bad. I guess that's because OpenGL can't run as fast as OpenGL ES on Raspberry Pi.

2314.patch.txt
Here is the patch fixed the the most problems except this bit:

/usr/bin/ld: CMakeFiles/tangram.dir/platforms/common/platform_gl.cpp.o: in function `Tangram::GL::mapBuffer(unsigned int, unsigned int)':
platform_gl.cpp:(.text+0x134): undefined reference to `glMapBufferOES'
/usr/bin/ld: CMakeFiles/tangram.dir/platforms/common/platform_gl.cpp.o: in function `Tangram::GL::unmapBuffer(unsigned int)':
platform_gl.cpp:(.text+0x144): undefined reference to `glUnmapBufferOES'
collect2: error: ld returned 1 exit status

After "sudo rpi-update" update the firmware, this bit has been fixed in https://github.com/tangrams/tangram-es/blob/main/platforms/rpi/config.cmake by using

target_link_libraries(tangram
  PRIVATE
  tangram-core
  ${FONTCONFIG_LDFLAGS}
  curl
  pthread
  rt
  /opt/vc/lib/libbcm_host.so
  /opt/vc/lib/libbrcmEGL.so
  /opt/vc/lib/libbrcmGLESv2.so
  /opt/vc/lib/libvchiq_arm.so
  /opt/vc/lib/libvcos.so
  -latomic
)

After built it successfully, I got the same "* failed to add service - already in use?" issue here #2214 when run it.
