stm32wb0x error on build of stm32cube example projects

[LVanr.1]

I'm trying to import the sample project BLE_Skeleton. On build I get the following error:

fatal error: osal.h: No such file or directory

The same error occurs for other BLE sample projects.
The error also happened for BLE_p2pServer but was fixed.

When can the problem be fixed for the other sample projects ?

how are you obtaining the sample project BLE_Skeleton?

If downloading from GitHub, see:

In stm32Cube I do: File > Import > Import STM32Cube Example

Hello @LVanr.1 ,

Maybe you have wrong paths! Try adding correct paths to the include directories (Go to Project options ->C/C++ tab->Include paths)

Otherwise, please provide more details on your CubeWB0 firmware package version and CubeIDE version used, the exact project path and steps?

Let me mention that I am learning about BLE development on ST (but I am very familiar with BLE development in Eclipse on other hardware platforms).

I had installed STM32Cube version 1.16.0. I installed BLE_Sketeton as well as other example projects BLE_p2pServer  and BLE_Beacon. All of these compiled properly and worked on my development board SRM32wb09KE.
A while ago some example projects did not compile and required an upgrade of MX. When warned that a new version of Cube was available I accepted doing the upgrade -- STM32Cube was automatically upgraded to version 1.17.0. MX was also upgraded. To make sure that the example projects were in sync I deleted them and installed them. That is where the compile error occurred. At first, project BLE_p2pServer also had the compile error. Little later I re-installed BLE_p2pServer and the compile error had gone but not for the other BLE sample projects.

I now desperately need BLE_Skeleton to start product development, hence my error posting.

I may assume that example projects are correct and working. It is not up to me to set paths or whatever.

About installing BLE_Skeleton. In stm32Cube I do: File > Import > Import STM32Cube Example. In MCU/MPU select STM32WB09KEV6TR. From the list of sample projects, select BLE_Skeleton, then Next --> project gets installed. Compile ==> error.

[LVanr.1 · Accepted solution]

(I got the solution via direct contact with an ST employee)

CubeMX > Project Manager > Code Generation > select 'Add necessary library files as reference.....'
Save and compile.

Thanks.  Now please mark that as the solution.
