Raspberry Pi 4 compile issues

[MyraBaba]

Hi,

I try to compile gl2handpose in rpi4 it gives below error:

g++ -o gl2handpose -Wl,--whole-archive main.o tflite_handpose.o render_handpose.o shapes.o touch_event.o custom_ops/transpose_conv_bias.o /home/pi/bcwork/tflite_gles_app/common/assertgl.o /home/pi/bcwork/tflite_gles_app/common/assertegl.o /home/pi/bcwork/tflite_gles_app/common/util_egl.o /home/pi/bcwork/tflite_gles_app/common/util_shader.o /home/pi/bcwork/tflite_gles_app/common/util_matrix.o /home/pi/bcwork/tflite_gles_app/common/util_texture.o /home/pi/bcwork/tflite_gles_app/common/util_render2d.o /home/pi/bcwork/tflite_gles_app/common/util_debugstr.o /home/pi/bcwork/tflite_gles_app/common/util_pmeter.o /home/pi/bcwork/tflite_gles_app/common/util_tflite.o /home/pi/bcwork/tflite_gles_app/common/winsys/winsys_x11.o /home/pi/bcwork/tflite_gles_app/common/util_camera_capture.o /home/pi/bcwork/tflite_gles_app/common/util_v4l2.o /home/pi/bcwork/tflite_gles_app/common/util_drm.o render_imgui.o /home/pi/bcwork/tflite_gles_app/third_party/imgui/imgui.o /home/pi/bcwork/tflite_gles_app/third_party/imgui/imgui_draw.o /home/pi/bcwork/tflite_gles_app/third_party/imgui/imgui_widgets.o /home/pi/bcwork/tflite_gles_app/third_party/imgui/examples/imgui_impl_opengl3.o -Wl,--copy-dt-needed-entries -Wl,--allow-multiple-definition -L/home/pi/bcwork/tflite_gles_app/third_party/tensorflow/current/lite/lib/current/ -L/home/pi/lib -lm -lEGL -lGLESv2 -lX11 -pthread -ldrm -ltensorflowlite -ltensorflowlite_gpu_delegate -Wl,--no-whole-archive -rdynamic
/usr/bin/ld: cannot find -ltensorflowlite
/usr/bin/ld: cannot find -ltensorflowlite_gpu_delegate

In my raspbery there is already libtensorflow-lite.a but not tensorflowlite_gpu_delegate lib.
more over -l-ltensorflowlite but there is libtensorflow-lite.a ?

what will be the proper compiling environment ? just clone the repo to my Desktop ubuntu and compile than copy to rpi ? or do I need any docker something ?

Did you build the tensorflow library following the below procedure described in README ?

• 32bit: https://github.com/terryky/tflite_gles_app#22-build-for-aarch64-linux-jetson-nano-raspberry-pi
  or
• 64bit: https://github.com/terryky/tflite_gles_app#23-build-for-armv7l-linux-raspberry-pi

No it was already builded. Tried to steps in Mac OS X but some other errors. Now restarting all steps in my ubuntu 20.04 and let you know. Best

Now all is successfully worked for handpose.

Is there an option video or cam input or do we need to modify code ?

USB camera can be used without any source code modification.

To use a mp4 video, follow the below instructions.
