Attiny AVR compiling Error -9

Development Platforms
1

The problem is that the compilation of the atmelavr Attiny project ends with a -9 error.
It does not matter if I do it in Atom and in old projects that I used to work, or in freshly installed Visual Studio and Platformio and new projects added directly from the wizard. No matter if it’s a clean AVR or Arduino environment. Each compilation attempt ends with a -9 error.

Environment: macOS 10.14.1 (18B75). Restoring and re-establishing Platformio and updating platforms does not help. What should I do?

ESP8266 compiles correctly at this same time.

2

Can you post the full error message and a minimal sample project for exact reproduction? What does pio --version say? Does this occur on other computers or computers with different operating systems as well (if you have any)?

3

Any project with Attiny AVR. This s error from default empty project from wizzard.

I don’t have other computers, only Mac. All works… 3 months ago? During this time, I worked only on ESP NONOS projects. These work all the time.

I cannot reproduce this on my Windows PC. Might be MacOS-only issue or a somehow corrupted PIO installation. So we must wait for someone with a Mac to troubleshoot this.

Do you get any additional information using verbose with -v ?

OK…
Any suggestions, what to delete, what to reinstall?

Uninstalling Toolchain AVR and reinstalling does not help.

It also has an environment for ESP32 in the system (off platform).

7

Do you use antivirus tool? It might block build system and remove compiled objects.
