Re: [edk] Porting disk utilities to internal commands

[Daniel M. <dan...@er...>]

I have been trying to port efifmt utility using the tutorial present in the shell developer´s guide and this is what I got:

In Shell.inf in [sources.common] I added:

EfiDiskUtility\efifmt\efifmt.cxx


In the DSC build file, in order to compile the cxx:

[compile.x64.cxx]


In efifmt.cxx there is this code:

-------------------------------------

extern "C"
EFI_STATUS
EFIAPI
InitializeEfiFmtApplication(
    IN EFI_HANDLE           ImageHandle,
    IN EFI_SYSTEM_TABLE     *SystemTable
    );

extern "C" {
EFI_APPLICATION_ENTRY_POINT (InitializeEfiFmtApplication)
}

extern "C" {
EFI_STATUS
EFIAPI
InitializeEfiFmtApplication(
    IN EFI_HANDLE           ImageHandle,
    IN EFI_SYSTEM_TABLE     *SystemTable
    )
{
    EFI_LOADED_IMAGE    *LoadedImage;
    EFI_STATUS          Status;

    /*
     *  Initialize the....

-------------------------------------

And then in the cmddisp.c I added this in the "SEnvInternalCommands[] = {":

  InitializeEfiFmtApplication,
  L"efifmt",

And this in the "EFI_MONOSHELL_CODE" :

EFI_STATUS
EFIAPI
InitializeEfiFmtApplication(
    IN EFI_HANDLE           ImageHandle,
    IN EFI_SYSTEM_TABLE     *SystemTable
    );



I think I have followed the steps in the tutorial (which had worked for me using other applications made by my own) nevertheless I continue to get this message when trying to build the shell:


ShellLocal.lib(cmddisp.obj) : error LNK2001: unresolved external symbol InitializeEfiFmtApplicat

NMAKE : fatal error U1077: 'C:\EDK\Sample\Platform\X64\Build\Tools\ProcessDsc' : return code '0x

What do you think am I doing wrong?

Thanks

Subject:        Porting disk utilities to internal commands

Hi!

I have been using the EFI Disk Utilities: http://www.intel.dk/technology/efi/agree_diskutil.htm and the mkramdisk in EFI toolkit to create a RAM filesystem. I am trying to port the applications so they can be used as internal commands in my EFI Shell.

I have successfully ported diskpart utility, cause it is written as any other kind of Shell application. Nevertheless, I am not able to port efifmt or eficheck. I mean, how should I modify Shell.inf file according to the EFI_Shell_Developer_Guide_Ver0-91 or the shell dispatcher, which are the entry points? Which .c files should I add to sources.common knowing the the sources are in .cxx format? And so on, I know that there must be a way, but I am a bit lost.

I will really appreciate some help :)

Thank you
