Cannot compile ground station

opened 11:58PM - 02 Apr 24 UTC

when trying to build the ground station it always errors at imgui, no such file …or directory. I tried the original jeanlemotan ground station and it runs so its something with your version. what version of raspi OS are you using? > Successfully installed Cython-0.29.37 PySDL2-0.9.16 cocos2d-0.6.10 glfw-2.7.0 imgui-2.0.0 pyglet-1.5.28 pi@ESP32FPV:/esp32-cam-fpv/gs $ make -j4 g++ -MT .o/src/main.o -MD -MP -MF .d/src/main.Td -std=c++17 `sdl2-config --cflags` -O3 -DNDEBUG -ffast-math -funroll-loops -Wall -Isrc -Isrc/utils -I../components/common -I/usr/include/ -I/usr/include/freetype2 -Isrc/imgui/ -Isrc/imgui//backends -DIMGUI_IMPL_OPENGL_ES2 -c -o .o/src/main.o src/main.cpp g++ -MT .o/src/HUD.o -MD -MP -MF .d/src/HUD.Td -std=c++17 `sdl2-config --cflags` -O3 -DNDEBUG -ffast-math -funroll-loops -Wall -Isrc -Isrc/utils -I../components/common -I/usr/include/ -I/usr/include/freetype2 -Isrc/imgui/ -Isrc/imgui//backends -DIMGUI_IMPL_OPENGL_ES2 -c -o .o/src/HUD.o src/HUD.cpp g++ -MT .o/src/PI_HAL.o -MD -MP -MF .d/src/PI_HAL.Td -std=c++17 `sdl2-config --cflags` -O3 -DNDEBUG -ffast-math -funroll-loops -Wall -Isrc -Isrc/utils -I../components/common -I/usr/include/ -I/usr/include/freetype2 -Isrc/imgui/ -Isrc/imgui//backends -DIMGUI_IMPL_OPENGL_ES2 -c -o .o/src/PI_HAL.o src/PI_HAL.cpp g++ -MT .o/src/Comms.o -MD -MP -MF .d/src/Comms.Td -std=c++17 `sdl2-config --cflags` -O3 -DNDEBUG -ffast-math -funroll-loops -Wall -Isrc -Isrc/utils -I../components/common -I/usr/include/ -I/usr/include/freetype2 -Isrc/imgui/ -Isrc/imgui//backends -DIMGUI_IMPL_OPENGL_ES2 -c -o .o/src/Comms.o src/Comms.cpp In file included from src/PI_HAL.h:3, from src/PI_HAL.cpp:1: src/IHAL.h:3:10: fatal error: imgui.h: No such file or directory 3 | #include "imgui.h" | ^~~~~~~~~ compilation terminated. make: *** [Makefile:131: .o/src/PI_HAL.o] Error 1 make: *** Waiting for unfinished jobs....

>>@RomanLut I have been checking out your esp32 fpc cam project, can you share a… binary for the esp32s3sense? >Well, I can build you binary for s3sense, but you also have to build ground station on Raspberry Pi 2W / 4. Have you managed to do it? >Currently I am not ready to release neither "hx_esp_now screenshots over telemetry" nor esp32cam-fpv project because I did not finished my experiments yet. Attached are binaries compiled from current master. [firmware.zip](https://github.com/RomanLut/esp32-cam-fpv/files/14732044/firmware.zip) I am able to get 25-30FPS 800x600 up to 500m. But: 1) both camera and lens have bad quality 2) if many packets are dropped, then the whole frame is dropped which does not look nice. Considering that one can build FulldHD system based on OpenIPC project for $40 per air unit, I am still not sure if messing with esp32 worth it. https://github.com/RomanLut/esp32-cam-fpv/assets/11955117/48d03190-2c19-42f7-a19b-ce8216d1fb17
