Portenta Async Web Server compile issues

I have a 3 source file project (and 2 headers). It compiles OK in Arduino IDE 1.8, but I get error messages in VisualMicro.

The errors mention a variable that is declared void, however on the output display, it is showing the text from the base file.

Another word it is complaining about a non-existent error in .ino file B, but is showing text from .ino file A in the output

I am using the library

#include <Portenta_H7_AsyncWebServer.h>

and I declare the function

void handleRoot(AsyncWebServerRequest *request);

this is what gives the error


sample error below

Compiling 'EnviroWatch' for 'Arduino Portenta H7 (M7 core)                                                                                          (envie_m7)'

Thanks for the report.

To ensure we are using the correct library versions, and board package versions, please enable the options shown at the top of the page, and attach the full build output.

Thanks for the output. Please switch on both "compile verbose" and "show build properties" then send again.

Thanks

Thanks for sending the output again. 

Please switch off debugging and also set optimization to default.

If that fails please send the output again.

Move the code below to the same location as the other #includes such as #include <Wire.h>

Code
Select All
#if !( defined(ARDUINO_PORTENTA_H7_M7) || defined(ARDUINO_PORTENTA_H7_M4) )
#error For Portenta_H7 only
#endif

#define _PORTENTA_H7_AWS_LOGLEVEL_     1

#define USE_ETHERNET_PORTENTA_H7        true

#include <Portenta_Ethernet.h>
#include <Ethernet.h>
#warning Using Portenta_Ethernet lib for Portenta_H7.

#include <Portenta_H7_AsyncWebServer.h>
#include <string>


The automatic prototype generation is having a problem working out where to add the prototypes because there are #includes and then code and then more #includes. In that case the prototypes are placed after the 1st valid code which is before the #include <Portenta_H7_AsyncWebServer.h> . That is a problem.

The code above is in the file EthernetInterface.ino

The wire.h etc includes are in the file Envirowatch.ino

I cannot move them completely - but could create a separate .h file and lump them together. Some are not required in some files however.

What would be the best avenue?

Thanks

You can avoid the issue by adding your own prototypes after the relevent includes and before the methods and user types are used.

You probably only have to add the prototypes that are causing an issue which I think is just the first three. However these are the ones from the "combined .ino." .cpp that you sent. Visual Micro won't add them if you have done so already. The prototypes should be exactly the same as the funtion sugnature followed by a semi-colon ;

void handleRoot(AsyncWebServerRequest *request);
void handleNotFound(AsyncWebServerRequest *request);
void drawGraph(AsyncWebServerRequest *request);
void EthernetThread();
void InitializeSensors();
void Read_TMP117Sensor();
void Read_SHTC3Sensor();
void Read_SGP40Sensor();
void Read_FS3000Sensor();
void Read_OZONESensor();
void DoSumAndHourCalc();

Things are jumbled together.

The code abovem never appears in Envirowatch.ino

Some of the definitions are in EthernetInterface.ino (the first 3), and the rest are in SensorArray.ino

You can neatly put each prototypes wherever you want. Put them in the right files or in the project name.in
