OTA Problems

[wa0uwh]

I have been using esp32-cam-webserver V4.0 and the previous revisions for several months, but I still have not got the OTA to compile. So far, I have had to add "#ifndif NO_OTA" around the OTA code section to avoid compile errors.

I compile on Arduino 1.8.19 IDE

But, now it is time for me to resolve my OTA problem, and could use some help. I have updated the Boards, and updated the installed Lib's. I have followed the OTA section in the GitHub README. The only thing that I can think of is that I may have conflicting Lib's installed, but do not know which are needed and where others may conflict.

The following are the first 3 errors:

C:\Users\eldonb\Dropbox\Cloud\A1Projects\Arduino\ESP32_CAM\esp32-cam-webserver-4.0\daschr\esp32-cam-webserver_MultiStream\esp32-cam-webserver_MultiStream.ino: In function 'void setup()':

              ^~~~~~~

Any suggestion would be welcome.

This looks like your IDE + libraries are confused or corrupted; searching on the error messages will confirm this.
You will need to follow this up via the IDE help channels, I cannot debug it for you; the code does compile correctly with the IDE+ libraries+boards configured as described in the README.

Also, esp32-cam-webserver_MultiStream.ino is not what the sketch is called, eg you are on someone else's fork of the code, which is also something I cannot support.
