error for compiling ESp 32 dev module on arduino ide #6

I guess you need to installa the library for the DHT sensor, which is available in https://github.com/adafruit/DHT-sensor-library

make sure you have all the necessary libraries in the libraries folder of you IDE. libraries are always included at the top of a sketch: // #include <wire.h> // and have .h ending. |
|
how to solve this issue? Not used: /home/arduino-1.8.5/libraries/WiFi |
|
exit status 1 means it did not compile do you have two different WiFi.h libraries? if they have the same content it should not matter but if they are different it may use the wrong one. |
|
In the arduino's libraries folder there is only one wifi folder i can't find the other if there is any.. im trying to switch a led using esp32 |
|
hi, collect2.exe: error: ld returned 1 exit status exit status 1 |
|
What libraries did you include in your sketch and what is in the folders the error messages lead to? |
same problem.... have you solved this? |
