This may be off-topic here: Obviously you're attempting a cross-compilation for a STM32 microprocessor, and the trouble is in the ST libraries.

Hello Tauno Voipio

Yes, I'm working with STM32 in sw4stm32 (eclipse modified)

in the main file everything is OK, the features work

I don't know if you've clipped the image in your first post but I don't see the compiler being told the include path for the HAL header. Is the -I option missing?

If so, where did the Makefile come from? Did Eclipse generate it?
Post the entire build log (copy and paste it) .
It wouldn't hurt to see the one that works, too.

Fixing this depends on project setup. You've left out a lot of details.

Your code is plain wrong: the call to HAL_delay() does not match its declaration in the header file (which you do not show here).

This is actually a basic C/C++ question not directly related to Eclipse CDT.

When make executes it would be in the Debug directory which is C:\C++\CUBE MX32\Progekt9\I2C\SW4STM32\I2C\Debug if I'm not mistaken.
The compile command has a relative include path -I../I2C/HAL/inc which, from what I can see in the project view in your images, doesn't exist.
It may be unimportant as the compiler isn't complaining about any non-found headers.
Why is it there?

Tauno has a point, though.
Does the call match the declaration?

I don't use HAL or anything related to it so I don't know although I'm curious to know why it works in main.cpp (from your no error.jpg) but not in lcd1602.cpp.
Or did it never work in main.cpp and you have just shown a listing of a file you have never compiled?
Is it misspelled and maybe should be HAL_delay vs. HAL_Delay?

Hello David Vavra!
in the main.ccp this works and the code compiles
in the file lcd1602.cpp work functions that I made myself, as a function of HAL (Hardware Abstraction Layer) do not work

Well then, Efim you need to find out what's different between the two builds.
I don't have your files and no other way of finding it for you.
This is not a CDT problem. This site is for dealing with CDT issues and not for debugging your code.
If you really need more help in this area you should ask around at other places.

Best of luck
