clean up and build everything that error usually means that a .ppu, .o
etc file is been compiled with a different version of units than the
one linking.

Thank you, but I can't find where is the problem, I deleted everything
from proj\lb\i386-win32
and at lazarus  I  Run     "run / clean - build -> right corner,
delete" and then build.

How to find where is the path where something built with a bad version
of files?

I also tried this from another topic:
https://forum.lazarus.freepascal.org/index.php?topic=21279.0
"Search all .ppu and .o inside lazarus folder (with the exception
everything under fpc folder) and remove them. Try recompiling again."

But nothing


When compile running i see that the compiler create detailed log but
when it finished i cant find it, only just the warnings and hints and
errors,  can i log it somehow?

Finally, I found the solution...

My project name was DOM...

And the dom.lpr built to dom.o and dom.ppu  before the compiler found
the dom.pas and compiled it also dom.o and dom.ppu.
I changed my project name to domSomething....
