Hello.

I started to use vMicro yesterday and I got an error when I try to build the project:

Process must exit before requested information can be determined.
Error compiling .ino project source
Build failed for project 'ESP32-MICRO' 

Yesterday, I couldn't fix this and what I did was uninstall Visual Studio and vMicro. After that, the problem stoppped and I could use vMicro ok.

But today, to error is back.
I made some tests and I saw that in my simple project, when I add the ArduinoJson.h library, like this:

#include <ArduinoJson.h>
#include <ArduinoJson.hpp>

#include <WiFi.h>
#include <Adafruit_Sensor.h>
#include <DHT_U.h>
#include <DHT.h>
#include <Arduino.h>
#include "DHT11.h"
#include "handleMessages.h"
#include "Wireless.h"



#define DHTPIN 26
#define DHTTYPE DHT11
DHT dht11(DHTPIN, DHTTYPE);

void setup() {
	Serial.begin(115200);
	dht11.begin();
}

void loop() {
	handleMessages();
	sensorTemperatura(dht11);
	delay(1500);
}
 

I get the error.

In the other hand, when I remove the ArduinoJson library:

#include <WiFi.h>
#include <Adafruit_Sensor.h>
#include <DHT_U.h>
#include <DHT.h>
#include <Arduino.h>
#include "DHT11.h"
#include "handleMessages.h"
#include "Wireless.h"



#define DHTPIN 26
#define DHTTYPE DHT11
DHT dht11(DHTPIN, DHTTYPE);

void setup() {
	Serial.begin(115200);
	dht11.begin();
}

void loop() {
	handleMessages();
	sensorTemperatura(dht11);
	delay(1500);
} 

I can build the project without problems.

To use this library, I used vMicro menu "Add Library > User Installed".

I'd like to fix this problem and understand why this happens.

I've uploaded two files:
with_log.txt -> trying to build with ArduinoJson (error).
without_log.txt -> build ok without ArduinoJson.

Hello.

I have installed the new version sucessfully (Visual.Micro.Arduino.Studio_2023_0731_2205).

Anyway, it did not work. I make the same test (with and without the library) and keeps the same (  if I include ArduinoJson.h, the build fails).

Also, I did a google about the 32k limit and found some tutorials to remove this limit on windows and when I checked it, it has already done on my computer. So, I think my machine does not have the 32k limit.

There goes a new log of a new trying to compile.

I'm not sure if I created the .bat correctly...

I've copied right after the "Building project code ..." ("C:\Users\{...}) until right before (Process must exit before requested information can be determined.)

Is it correct?

If so, I get the error "No such file or directory"

Sorry. I didn't see your attached file.

But, anyway, I got the same error: "No such file or directory"

xtensa-esp32-elf-g++: error: pt.h: No such file or directory 

So, updates:

After create the empty header file and run the .bat that you provide, I could add the library <ArduinoJson.h> build the project with no problems.  Success.

But, I had to add another library:

#include <PubSubClient.h> // new library
#include <ArduinoJson.h>
#include <ArduinoJson.hpp>
#include <WiFi.h>
#include <Adafruit_Sensor.h>
#include <DHT_U.h>
#include <DHT.h>
#include <Arduino.h>
#include <time.h>
#include "DHT11.h"
#include "handleMessages.h"
#include "Wireless.h"

#define DHTPIN 26      
#define DHTTYPE DHT11 
DHT dht11(DHTPIN, DHTTYPE);

void setup() {
	Serial.begin(115200);
	dht11.begin();
}

void loop() {
	handleMessages();
	sensorTemperatura(dht11);
	delay(1500);
}
 

and this gives me build error again.
Log is attached.

EDIT:

Looking in the log, I got the code between "Process: ..." and "Process must exit before requested information can be determined." and run in cmd. After that, I could compile well again.

Is there a final solution?

I still building this way.. getting the script about the error and running as a bat.

Tested right now and It took 107 seconds. 
Usually, it is taking no less than 1 minute and max 3min.

I installed 23.0731.07 and seems that the problem is fixed.
However, I didn't make any big change on project or added libraries.

In the next 3 days and I'll start a new project which will take a lot of builds and I think we will be able to close as fixed.

Yes, I've been getting very long build times.

I don't know why, but using ESP32 I get this problem, while with Arduino uno it is very fast.

E.g, complete build with arduino uno: 50s. Same complete build with esp32: 12min.

Antivirus: I usually don't use it, but since i'm using my university laptop, I cant disable. Symantec Endpoint Protection. Version 14 (14.3 RU6) build 9210 (14.3.9210.6000).

This high time build time is a problem for me and I was going to open a new topic about it, but it is related to the main problem... Can we discuss about it here?

Thank you!

1st ESP32: 323 secs.
2nd ESP32: 5 sec.

1st Arduino: 8s.
2nd Arduino: 1s.

My config: 32GB ram, i7 11850h processor, 1TB SSD m.2.

Usually, when I'm working with ESP32 and need to add a new Library, it takes soo long.


Attachs:
Log for slow build.
vMicro - compiler, general and debugger options.

Questions:
1 - Do you see any reason to very slow (more than usual) working with ESP32?
2 - Where can we access examples from vMicro? I had to copy from arduino IDE.
