Hi, i did all the points, described in the wiki: Installation of the libraries and commented out the sensor.h in Adafruit_BME280.h. Unfortunatelly i get the following error while compiling:

sketch/esp32-camera-bme280.ino.cpp.o:(.literal._Z5setupv+0x6c): undefined reference to `startCameraServer()'

sketch/esp32-camera-bme280.ino.cpp.o: In function setup()': /home/dragon/Arduino/Sketchbook/esp32-camera-bme280-master/esp32-camera-bme280/esp32-camera-bme280.ino:291: undefined reference tostartCameraServer()' collect2: error: ld returned 1 exit status exit status 1 Fehler beim Kompilieren für das Board ESP32 Wrover Module.

I tried to compile with the" ESP32 Wrover Module" and with "TTGO LoRa32-OLED V1" -Boards and got always the same error. Could you help me please. Thanks a lot

This is the project directory was reset by Arduino, please open the project directory and rename esp32-camera-bme280-master to esp32-camera-bme280, and ensure that the contents are the same as the following figure. 2019-02-09 10 32 18

Thank you very much, now it works perfect, with " ESP32 Wrover Module" as Board.

Привет, я сделал все пункты, описанные в вики: Установка библиотек и закомментировал sensor.h в Adafruit_BME280.h. К сожалению, я получаю следующую ошибку при компиляции: sketch / esp32-camera-bme280.ino.cpp.o :(. literal._Z5setupv + 0x6c): неопределенная ссылка на startCameraServer () sketch / esp32-camera-bme280.ino.cpp.o: В функции setup()': /home/dragon/Arduino/Sketchbook/esp32-camera-bme280-master/esp32-camera-bme280/esp32-camera-bme280.ino:291: undefined reference tostartCameraServer () ' collect2: error: ld возвращено 1 состояние выхода из состояния выхода 1 Fehler beim Kompilieren für das Плата ESP32 Wrover Module. Я попытался скомпилировать с "ESP32 Wrover Module" и с "TTGO LoRa32-OLED V1" -Boards и получил всегда одну и ту же ошибку. Не могли бы вы мне помочь, пожалуйста. большое спасибо

Этот каталог проекта был сброшен Arduino, пожалуйста, откройте каталог проекта и переименуйте esp32-camera-bme280-masterего esp32-camera-bme280, и убедитесь, что содержимое совпадает со следующим рисунком.

Good day friends! I ask for help, since I have a similar problem on Windows 10, arduino ide and ESP 32 ttgo T-camera. I tried to follow the examples of the solution that was described above, but nothing changes and I still could not compile the code. I am new to this and ask you, please help me to deal with this problem. Thank you very much in advance.
