So this error msg keeps poping up

Alternatives for config/classic_config.h: []ProffieOS:28:22: fatal error: config/classic_config.h: No such file or directory

config/classic_config.h: No such file or directory

I’m guessing that you do not have a config file called config/classic_config.h.
If you’re on windows, maybe you named it config/classic_config.h.h ? (And then windows hides the second “.h” for you.)

no i called it classic_config.h

DId you put it in the config directory?
Do you have the right ProffieOS.ino open? (Arduino tends to open things it had open in the past sometimes which can be confusing if you mean to open a different ProffieOS.ino)

I have never seen output like this before.
candidates: []?

Is that Arduino CLI or something?
What’s compiling?

its arduino

Well then something isn’t right with how you have it set up.
Those messages are not anything you’d get with compiling ProffieOS properly.
it might supposed to be ResolveLibrary(Wire.h)
I found an old post on TRA for example that has

Detecting libraries used...

-> candidates: [Wire@1.0]

So my money is on the Arduino-Proffieboard plugin.
Do you have the right plugin installed under Tools>Board>Boards manager? (Proffie 3.6.0)

i do proffie 2.2 com 3 and stm32 boot loader

No, that has nothing to do with what I mentioned.
Did you follow these setup instructions, specifically for the plugin?
