Errors in the configurator of the STM32CubeIDE for microcontroller STM32L100RB. (Not observed for STM32F103, etc.) (Low Layer only)

[ATret.3]

Ubuntu STM32CubeIDE 1.8/1.7

File -> New -> STM32 Project

Choose STM32L100RB -> Next -> Project Name : "removeMe2" -> Finish

In Device Configuration Tool:

  Pinout&Configuration -> Connectivity -> SPI1 -> Mode: Full Duplex Master

  Project Manager -> Advanced Setting -> Driver Selector -> SPI: LL

Save and generate code.

./Core/Src/main.c: In function 'MX_SPI1_Init':

../Core/Src/main.c:210:3: warning: implicit declaration of function 'LL_SPI_SetStandard' [-Wimplicit-function-declaration]

Build Failed. 3 errors, 0 warnings. (took 901ms)

And I can't open declaration (Hotkey - F3) of LL_SPI_SetStandard(). (For other functions IDE try to open *.c file at first, but not *.h. Definition of LL_SPI_SetStandard() in the stm32l1xx_ll_spi.h)

Error in library.

Adding next simbols in the Project -> Properties -> C/C++ General - >Path and Symbols -> Symbols solves the problem (I think, it should be in CMSIS).
