I am a newbie trying to move from Arduino IDE to Eclipse and am keen to program AVR MCU (I'm new at this too).
I have successfully installed (I hope) winAVR and the AVR Eclipse Plugin.
I can use the Project | Properties | AVR | Target Hardware to interrogate the AVR (it's an Arduino Uno - ATMegga328P) and the Project | Properties | AVR AVRDude | Fuses | direct hex values | Load from MCU seems to communicate (flashing Tx Rx on Arduino Uno) and update fuse settings on screen.
I have built my 'blinky' code, saved it (main.c) and now want to get something uploaded onto my AVR but when I Build it, I get an avr-gcc.exe - Application Error dialog - The application was unable to start correctly (0xc0000142):
My environment on a Windows 10 Home 64bit machine:
Eclipse IDE for C/C++ Developers (includes Incubating components)
Version: 2021-03 (4.19.0)
Build id: 20210312-0638
AVR Eclipse Plugin 2.4.2 de.innot.avreclipse.feature.group avr-eclipse.sourceforge.net
avrdude version 5.10, URL:
More detailed description of issue:
The command line Eclipse is trying to execute is:
avr-gcc -Wall -Os -fpack-struct -fshort-enums -ffunction-sections -fdata-sections -std=gnu99 -funsigned-char -funsigned-bitfields -mmcu=atmega328p -DF_CPU=1000000UL -MMD -MP -MF"main.d" -MT"main.o" -c -o "main.o" "../main.c"
I was trying to use an IDE so I didn't need to use the command line directly. However I looked up an a article (How to compile and burn the code to AVR chip on Linux/MacOSX/Windows 2016-01-08 by Łukasz Podkalicki) to get a simplified command to see if there was a fundamental issue and this ran as below.
C:\Users\Peter\OtherWorkspace\Bliknk2>avr-gcc -Wall -g -mmcu=atmega328p -o main.bin main.c

I must be close with the Eclipse setup but something must be incorrect. Please can you help me? What have I done wrong?

Well things have changed but still no solution:
I researched the error and ran
C:>DISM.exe /Online /Cleanup-image /Restorehealth
Then I ran
C:>sfc /scannow
It did claim to fix some things but I had the same result as before.
I also started PC in clean mode - with all the start up junk disabled just in case there was some type of app conflict.
Then I located the avr-gcc.exe and had Windows run Troubleshoot compatibility (right click on .exe)
Running Build in Eclipse now gives me a different error - Permission denied - I think the Troubleshoot compatibility utility was running avr-gcc.exec as administrator - I certainly had to confirm access before it was launched by Eclipse. Not sure I can get any more permissions higher than administrator.
I feel I am getting closer but I do not know how to resolve the issue. Maybe a complete re-install of Eclipse? I don't know.
Please help me if you can.
Best regards Peter

I struggled with this recently.
Turns out I had 2 versions of AVRGCC installed. The older one was on the path, so the Make process would use 'make' from the older version. But that make would invoke avr-gcc in the newer version, which it had a problem with, generating this error.
So drop to a command line and type 'where make' to see where it's being called from.
