Unable to build a simple project

Hello everyone, I’m still new to using platform.io and I’m having a difficult time building a simple blink program. I’ve tried uninstalling both vscode and platformio but the problem still persist. I would appreciate any help. Thank you very much.

main.cpp

#include <Arduino.h>

void setup() {
  // put your setup code here, to run once:
  pinMode(LED_BUILTIN,OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
  digitalWrite(LED_BUILTIN,HIGH);
  delay(1000);
  digitalWrite(LED_BUILTIN,LOW);
}

platformio.ini

Either your toolchain was corrupted or antivirus is blocking execution of it.

As a first step, please remove the C:\Users\<user>\.platformio\packages\toolchain-atmelavr folder completely, then try building again.

Hi, I disabled my firewall and deleted the toolchain-atmelavr folder and rebuilding but the error is still there.

Open a CLI and execute

C:\Users\<user>\.platformio\packages\toolchain-atmelavr\bin\avr-gcc --version

what does it output?

PS D:\Arduino Uno Blink Test> C:\Users\Charles\.platformio\packages\toolchain-atmelavr\bin\avr-gcc --version

Looking good, so at least avr-gcc does not seem corrupted.

Do you have an antivirus program active on the system beyond Windows Defender?

No, I double checked and window defender should be the only one I have on this computer

Can you copy-paste the output of the project task “Advanced → Verbose Build”?

last exitvalue:

PS D:\Arduino Uno Blink Test>

Funny how it works inside the shell, exit code 0 is ‘success’.

I see that PlatformIO is installed on the C: drive and the project is on D:. Does this project, when created in the standard C:\Users\<user>\Documents\PlatformIO\Projects folder also fail the same way? Is D:\ a network-mapped drive?

Remember if a new project is created, you must manually switch to it with the project environment switcher.

I was not aware of the environment switcher but when I recreated the project in the default folder it still produces the same error.

Running the two commands in the CLI:

I really have no idea why individual compiler commands work in a CLI but not when PlatformIO invokes it. My first huch is always an interfering antivirus, but if you say there is none, then that can’t be.

Try a complete clean reinstall. First, remove the PlatformIO VSCode extension, close VSCode, remove the C:\Users\<user>\.platformio folder completely, then restart VSCode and install the PlatformIO extension.

Then try to create a new project again, but this one without spaces in the project name for safety reasons, and attempt to build it again.

Alright, I completely deleted everything platformio related and reinstalled the extension but the issue still persist. I’m not sure what the problem is either.

For reference what does pio system info output in the CLI?

Does the behavior change after you do a pio upgrade --dev?
