构建失败 EDK2

Question

我得到：

d:\edk2\SetVariablePkg\SetVariablePkg.dsc(...): error 4000: Instance of library class [OpensslLib] is not found
        in [d:\edk2\CryptoPkg\Library\BaseCryptLib\BaseCryptLib.inf] [X64]
        consumed by module [d:\edk2\SetVariablePkg\SetVariable.inf]

当我尝试编译我的 EDK2 项目时。 我正在尝试使用

RandomBytes()

函数，因此我包含了

<Library/BaseCryptLib.h>

。这就是我的 .dsc 文件的样子：

[Defines]
    PLATFORM_NAME = SetVariablePkg
    PLATFORM_GUID = 4E85F56A-569F-41FC-AA95-C0C42519E406
    PLATFORM_VERSION = 0.1
    DSC_SPECIFICATION = 0x00010005

[Components]
    SetVariablePkg/SetVariable.inf

这就是我的 .inf 文件的样子：

[Defines]
    INF_VERSION = 0x00010006
    BASE_NAME = SetVariable
    FILE_GUID = 53EF0710-78CA-40EF-AFF8-CAC311DBEB38
    MODULE_TYPE = UEFI_APPLICATION
    VERSION_STRING = 0.1
    ENTRY_POINT = UefiMain

[Sources]
    SetVariable.c
    SetVariable.h

[Packages]
    MdePkg/MdePkg.dec

[LibraryClasses]
    UefiLib
    MemoryAllocationLib
    UefiBootServicesTableLib
    UefiApplicationEntryPoint
    UefiRuntimeServicesTableLib
    BaseCryptLib

[Protocols]
    gEfiSimpleTextInputExProtocolGuid

这些是我在头文件中的包含内容：

#include <Uefi.h>
#include <Library/UefiLib.h>
#include <Library/UefiBootServicesTableLib.h>
#include <Library/UefiRuntimeServicesTableLib.h>
#include <Library/MemoryAllocationLib.h>
#include <Library/BaseCryptLib.h>
#include <Protocol/Variable.h>

#define Buffer 256

我使用的是Windows 10，使用VS2019编译器。有谁知道我该如何修复这个错误？

Answer 1

错误消息表明您错过了在 .dsc 文件中定义库“OpensslLib”的实例。

您可以在 .dsc 文件中定义 OpensslLib，如下所示

OpensslLib|CryptoPkg/Library/OpensslLib/OpensslLib.inf

对于新的类似错误，您可以在其他 .dsc 文件上搜索参考。
