They are both enabled :/

I tried out some new things in this time. Tried installing codeblocks 17.12 because i saw my university computers were running that version. When i tried compiling a program there codeblocks just crashed to desktop without any error message. When uninstalling 17.12 everything was deleted but the MinGW folder and it's contents couldnt be deleted without a restart.(might not be meaningful to my issue but worth mentioning.)

I also tried installing the Codeblocks version that doesnt come with MinGW and installed MinGW from another source. Both installations were successful and Code blocks autodetected the MinGW directory. I got the same error message as i do with the pre-packaged compiler.

Could it just be that my computer isn't compatible with something? I am using a Lenovo Legion 5 with Ryzen 5 4600H and GTX 1650 TI. Also using the newest 64bit version of Windows 10 pro

Can you attach the .CBP file?

I did another fresh Windows reinstall and Code Blocks is working for now. Thanks for the people who tried to help, i'll try to not disturb the balance and hope it continues to work. Trying to get this to work was way to stressful and time consuming lmao

I suggest you start by looking in the C::B manual:

Post a full rebuild log in code tags, see this for help

Dear All,

By standard i use Visual Code for porgramming on Linux Machines, but want to try out Code::Blocks.
Well i have the same issue with the build in example under Debian 11.

I checked the log message and did the same compiling steps by hand via xterm... and it works like it should. 
So it seems that the origin of this issue depends on Code::Blocks.
When i checked the directorys of the project, i recognized that there is no main.o file generated in the <obj\Debug> directory.
Maybe the settings in the compiler options could be the reason ?!

Regards

Have you checked the access rights in the project folder?
Can you share your project?
can you reproduce it with a minimal hello world project?

Hi All,

I think i have found a solution for me regarding this issue.
Situation is/was that i normally use an account with root-rights on my development machine (to make some things easier).
I reminded that i had a similar issue with root-rights with another software some time ago.
So i have setup a new user with 'non-root-rights' and well, .... now it works... 

Regards

Check that the name of the folder that content your program is correct (whithout special character)

please help for this error in code blocks

To hs:

Code Select Expand

-mmcu=atmega8

The above is likely wrong.

You likely want

Code Select Expand

-mmcu=avr4 along with

Code Select Expand

-D__AVR_ATmega8__

This info found on https://gcc.gnu.org/wiki/avr-gcc

Note: Please tell us whether a CB Wizard or you the user set these values.

Edit: Looks like the CB Wizard and Compiler settings; I am guessing both being wrong is not likely; maybe the just the linker using

Code Select Expand

-mmcu=atmega8 is wrong, instead.

So, since you tried everything there is no way I can help you.
Good luck and Good bye.
Reading the FAQs might help; but, you already did that!
You already tried building the project in a folder you have read/write permissions.
