'GPIOB' could not be resolved error [message #1816108]

Hello!

I'm new to eclipse. I was following several manuals to guide me through installation process. I've installed eclipse, GNU MCU plugin, JRE, arm-none-eabi-gcc, configured warkspace, even installed stlinkv2 and it works. I've generated basic code with cubeMX and imported it as Makefile GNU ARM project to eclipse. I have no errors while building project, but when I open main.c file there are several semantic errors. The compiler can not recognize everything what uses GPIO. Here is this errors:

I suppose that I missed some plugins or did something wrong with toolChain configuration, but I can not figure out what's wrong. Can anyone please help?

Those don't look like compiler errors.
GNU compiler errors have a different format.

They are likely caused by a confused Indexer or Syntax Analyzer.
Could also be something weird about your code.
But try some of the suggestions here:
https://stackoverflow.com/questions/8148235/eclipse-cdt-shows-semantic-errors-but-compilation-is-ok

One of them is to turn off the Syntax Analyzer as a last resort.

EDIT:
Found this and it superficially looks like your problem.
I only scanned it but it's more recent and might help
