Include files shown in Solution explorer- cannot open source file

The included files are in subdirectories under \src. It is shown in the project. On build the systems appears to locate the file but reports an error: that it can't find or open the include files.

For example Quote:
src\driver\WiFi.h


E1696      cannot open source file "WiFi.h"      SoftRF      C:\Users\steph\Documents\Arduino\SoftRF\src\platform      C:\Users\steph\Documents\Arduino\SoftRF\src\platform\ESP32.h      27            


The file exists and seems to be in a folder that should be searched.

please provide the information request in yellow near the top of the page.

It looks like that file is included from the esp32.h which would normally be an esp core file. it would not make sense to have a wifi.h in the project. remove the one from the project src folder or below that. the esp32 core should then use the correct one.

Tim,
I'm not sure which part I haven't complied with. I:

Enabled vMicro > Compiler > Show Build Properties

and

attached the saved output as a txt file to my original post.
Please let me know what you need me to do.

I am attempting to build a Github project SoftRF, which I believe (I haven't checked) compiles in the Arduino IDE.

The ESP32.h is not part of the ESD Framework but a project file. So is WiFi.h

What I am trying to work out is why a file that is known in the solution (wifi.h) 'cannot be found' in the build phase.

Can you also enable vMicro > Compiler > Verbose and attach a fresh compilation log?

Can you confirm it is the below project (and if not can you link to the project you are using so we can replicate):
https://github.com/ksjkl1/TTGO-Helltec-WiFi-LoRa-ESP32-SoftRF-1.0-EU

If it is the above project it looks to have not been updated in a long time, and the ESP32 core has moved a long way since then.  The guide states it was documented using v1.0.5, have you tried rolling back to that version and compiling?

Simon,
please find a build output with verbose option on.

the project I am trying to build is:
https://github.com/lyusupov/SoftRF

The latest version 1.7 is 5 days old.

TIA

Thanks for the updated log and detail.

Can you enable vMicro > Compiler > Deep Search for Libraries + Accurate Prototype Insertion (Gcc-E), and then recompile the project.

Thanks for the log.

If you have vMicro > Compiler > High Speed Parallel Builds enabled, can you try it again with this option turned off?

The very latest ESP32 board package (v3.2.0) should also work with this project, as you correctly stated earlier this is a very active and up to date project.

I tried disabling parallel builds. After hours it hadn't completed. (BTW I never get beyond 20% CPU even with it enabled. VSC and Platformio goes quicker.)
