Hi Ivan,
It seems that probably you might be getting the error because of your .inf File. Do you want your UEFI module to be a UEFI_DRIVER or UEFI_APPLICATION? I am assuming UEFI_DRIVER.
Is there a reason why you need to access the UEFI Shell protocol from your driver?
Typically it is not best practices to have a dependency on the UEFI Shell within a driver since the UEFI Driver is called from the UEFI Dispatcher and not from the Shell.
Some good examples of a UEFI Driver are in https://github.com/tianocore/edk2/tree/master/MdeModulePkg of which the SCSI driver is a good single example: https://github.com/tianocore/edk2/tree/master/MdeModulePkg/Bus/Scsi/ScsiDiskDxe
Here is an example of a UEFI Application:
https://github.com/tianocore/edk2/tree/master/MdeModulePkg/Application/HelloWorld
Here is an example of a super simple UEFI Application: https://github.com/tianocore/tianocore.github.io/wiki/Getting-Started-Writing-Simple-Application
Thanks,

Subject: UEFI Driver Libraries problem
Hello,
at the beggining I wanted to say, that maybe here on this page it will be easier to understand my problem, there are some pictures explaining and nice code formatting:
https://stackoverflow.com/questions/53741304/compile-uefi-application-driver-using-edk2
I'm trying to build UEFI Application/Driver, but I get errors when I'm trying to include library:
#include "C:\MyWorkspace\ShellPkg\Include\Library\ShellLib.h"
Errors:
1>Building ...
c:\myworkspace\MdeModulePkg\Library\CustomizedDisplayLib\CustomizedDisplayLib.inf
[IA32]
1>C:\MyWorkspace\ShellPkg\Include\Library\ShellLib.h(22): fatal error
C1083: Cannot open include file: 'Protocol/EfiShellInterface.h': No such file or directory
1>NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual
Studio\2017\Enterprise\VC\Tools\MSVC\14.16.27023\bin\Hostx86\x86\cl.exe"'
: return code '0x2'
If I try another method:
EFI_STATUS
EFIAPI
BootCheckDriverEntryPoint (
IN EFI_HANDLE ImageHandle,
IN EFI_SYSTEM_TABLE *SystemTable
)
{
EFI_SHELL_PROTOCOL *EfiShellProtocol;
EFI_STATUS Status;
Status = gBS->LocateProtocol(&gEfiShellProtocolGuid,NULL,(VOID
**)&EfiShellProtocol);
//
// Install UEFI Driver Model protocol(s).
//
Status = EfiLibInstallDriverBindingComponentName2 (
ImageHandle,
SystemTable,
&gBootCheckDriverBinding,
ImageHandle,
&gBootCheckComponentName,
&gBootCheckComponentName2
);
ASSERT_EFI_ERROR (Status);
return Status;
}
I get.. linker errors I suppose. I also tried to include some libraries in property pages, but I'm not very familiar with Visual Makefile project, I could have done something wrong.
1>Building ...

I would appreciate any useful information, thank you.
