ESP32 E0070: incomplete type is not allowed and E0075: operand of '*' must be a pointer

Hello,

I'm compiling for a ESP32 board for the first and encoutering these errors

"E0070 incomplete type is not allowed xtruntime-core-state.h  lines 166-171" which is this line STRUCT_AFIELD_A(char,1,XCHAL_CP0_SA_ALIGN,CS_SA_,cp0,XCHAL_CP0_SA_SIZE)

"E0075 operand of '*' must be a pointer random.h lines 80-82"

"E0075 operand of '*' must be a pointerstl_bvector.h line 68"

I found this when googling the first error https://github.com/espressif/esp-idf/issues/2744 which suggested that its a Visual Micro configuration error?

I'll be grateful for suggestions/assistance please on how to resolve these errors.

Thanks Paul

Thanks for the report.

Can you attach the contents of the Output > Micro Build window, with the settings shown at the top of this page, for a clean build?

If it is possible to supply the sketch in use it would help greatly with our investigation.

Hello, it seems that these errors only appear in the error list but don't prevent the project from being built.

I am now encountering other errors in the build after adding libraries

There are probably two seperate issues. One is a build error because the AsyncTCP library can't be found. Do you have it installed? It is here if not.

https://github.com/me-no-dev/AsyncTCP/archive/master.zip

The other is confusion with the Visual Studio intellisense that is seperate to the build process. It is possible to alter the combo box above the errors list to "Build Only". Then you will only see the more accurate build errors. Alternatively above the errors list is another combo that can be set to Project Only, that will exclude the underlying sources from intellisense error reporting.
