在linux中构建edk2

问题描述 投票：0回答：3

我开始用 edk2 编写一个简单的小应用程序。

所以要编写一个简单的 edk2 UEFI 应用程序，我是这样开始的：

#git 克隆 https://github.com/tianocore/edk2.git

#. edksetup.sh BaseTools

Loading previous configuration from /media/ledoux/Data/osdev/devos/edk2/edk2/Conf/BuildEnv.sh
WORKSPACE: /media/ledoux/Data/osdev/devos/edk2/edk2
EDK_TOOLS_PATH: /media/ledoux/Data/osdev/devos/edk2/edk2/BaseTools
CONF_PATH: /media/ledoux/Data/osdev/devos/edk2/edk2/Conf

#vi Conf/target.txt

（在那里，我已经放了： 目标架构 = IA32 X64 TOOL_CHAIN_TAG = VS2017)

# BUILD -a X64

Build environment: Linux-5.7.0-kali1-amd64-x86_64-with-glibc2.29
Build start time: 08:32:11, Sep.03 2020

WORKSPACE        = /media/ledoux/Data/osdev/devos/edk2/edk2
EDK_TOOLS_PATH   = /media/ledoux/Data/osdev/devos/edk2/edk2/BaseTools
CONF_PATH        = /media/ledoux/Data/osdev/devos/edk2/edk2/Conf
PYTHON_COMMAND   = /usr/bin/python3.8


Processing meta-data

..................

为什么构建失败？ 是因为存储库不好吗？ 构建后如何创建 OVMF.fd 文件???

您是在 Linux 下构建的，因此您没有 Visual Studio（VS2017 所指的就是 Visual Studio）。构建系统确实应该说一些更有用的东西，但是......我可以从自己的实验中确认它没有。

改用 GCC5 工具链标签 - 该标签对于最新的 gcc10 版本仍然有效。

这是 Linux Ubuntu 20 的完整教程。它在我这边运行得非常好。

设置 EDK2

以下是我为让 EDK2 在 Linux Ubuntu 20 上运行所采取的步骤：

  1. sudo apt-get install build-essential git uuid-dev iasl nasm python python3-distutils python3-apt

  2. git clone https://github.com/tianocore/edk2.git

  3. 从这里下载brotli（第三个文件）

  4. 安装在 

    ~/edk2/BaseTools/Source/C/BrotliCompress/brotli

  5. cd edk2

  6. make -C BaseTools

  7. 运行

    . edksetup.sh
    （包括点）

  8. 在文本编辑器中打开 

    Conf/target.txt
    进行更改
    ACTIVE_PLATFORM 至 
    MdeModulePkg/MdeModulePkg.dsc

    TOOL_CHAIN_TAG 至 
    GCC5
    和
    TARGET_ARCH 至 
    X64

  9. 从这里下载oniguruma

  10. 复制

    brotli
    到
    ~/edk2/MdeModulePkg/Library/BrotliCustomDecompressLib/brotli
    和 
    oniguruma
    到 
    ~/edk2/MdeModulePkg/Universal/RegularExpressionDxe/oniguruma

  11. build

如果您在任何步骤关闭 bash 终端，只需重新运行 

. edksetup.sh
，因为这样您就无法运行 
build
命令。

编译您自己的 efi 应用程序

上面将简单地向您展示了它的一般工作原理。一旦所有这些工作正常，您想要编译自己的 Hello World 示例，如下所示。

#include <Uefi.h>

EFI_STATUS EFIAPI UefiMain (IN EFI_HANDLE ImageHandle, IN EFI_SYSTEM_TABLE  *SystemTable){
  SystemTable->ConOut->OutputString(SystemTable->ConOut, L"Hello World\n");
  return EFI_SUCCESS;
}

为了做到这一点，您需要采取更多步骤。

  1. 在edk2目录中创建一个工作目录，如

    ~edk2/BootloaderPkg
    。在其中放置 2 个文件，一个名为 
    Bootloader.c
    ，另一个名为 
    Bootloader.inf
    。

  2. 在

    Bootloader.c
    中放置上面的代码。在 
    Bootloader.inf
    中放置以下内容：

[Defines]
  INF_VERSION                    = 1.25
  BASE_NAME                      = Bootloader
  FILE_GUID                      = 66949615-9653-4a86-8c61-6ef0952973b9
  MODULE_TYPE                    = UEFI_APPLICATION
  VERSION_STRING                 = 1.0
  ENTRY_POINT                    = UefiMain

[Sources]
  Bootloader.c

[Packages]
  MdePkg/MdePkg.dec
  
[LibraryClasses]
  UefiApplicationEntryPoint
  UefiLib
    
[Guids]

[Ppis]

[Protocols]

[FeaturePcd]

[Pcd]
  1. 如https://github.com/tianocore/tianocore.github.io/wiki/Getting-Started-Writing-Simple-Application所述，

使用项目 .inf 文件更新现有平台 .DSC 文件。下面列出一些例子。

所以我所做的是从 MdeModulePackage 中获取 .DSC 文件，并使用以下内容对其进行了一些修改：

[Defines]
  PLATFORM_NAME                  = MdeModule
  PLATFORM_GUID                  = 587CE499-6CBE-43cd-94E2-186218569478
  PLATFORM_VERSION               = 0.98
  DSC_SPECIFICATION              = 0x00010005
  OUTPUT_DIRECTORY               = BootloaderPkg/Build
  SUPPORTED_ARCHITECTURES        = IA32|X64|EBC|ARM|AARCH64|RISCV64
  BUILD_TARGETS                  = DEBUG|RELEASE|NOOPT
  SKUID_IDENTIFIER               = DEFAULT

[Components]
  BootloaderPkg/Bootloader.inf

[BuildOptions]

将该内容放入名为 

BootloaderPkg.dsc
的文件中，并将其放入您的工作目录中。

  1. 将 Conf/target.txt 文件中的 
    ACTIVE_PLATFORM
    行更改为 
ACTIVE_PLATFORM       = BootloaderPkg/BootloaderPkg.dsc
  1. 完成此操作后，您就可以编译自己的 EFI 应用程序了。打开终端并输入以下命令：
cd edk2
. edksetup.sh
build

现在您应该在 

~/edk2/BootloaderPkg/Build
目录中拥有所有类型的文件，包括 
Bootloader.efi
，这是已编译的 EFI 应用程序。

测试 EFI 应用程序

很高兴拥有一个 EFI 应用程序，现在您想测试它。编写 bash 脚本并在其中键入以下命令（取自 UEFI - OSDev Wiki）：

dd if=/dev/zero of=edk2/BootloaderPkg/disk.img bs=512 count=93750
gdisk edk2/BootloaderPkg/disk.img  #o n ef00 w
sudo losetup --offset 1048576 --sizelimit 46934528 /dev/loop7 edk2/BootloaderPkg/disk.img
sudo mkdosfs -F 32 /dev/loop7
sudo mount /dev/loop7 /mnt
sudo cp edk2/BootloaderPkg/Build/DEBUG_GCC5/X64/Bootloader.efi /mnt
sudo umount /mnt
sudo losetup -d /dev/loop7

将该脚本放入您的主目录并启动该脚本。系统将提示您输入内容。按顺序键入 o、y、n、Enter、Enter、Enter、ef00、w，然后y。这将使您拥有一个使用 FAT32 分区的 

disk.img
以及其上的文件 
Bootloader.efi
（EFI 应用程序）。

完成后，您需要下载 OVMF 和 qemu，因此输入

sudo apt install ovmf qemu qemu-system-x86

完成后，输入以下命令以在 QEMU 中启动 EFI shell 并测试您的 EFI 应用程序。

sudo qemu-system-x86_64 -cpu qemu64 -drive if=pflash,format=raw,unit=0,file=/usr/share/OVMF/OVMF_CODE.fd,readonly=on -drive if=pflash,format=raw,unit=1,file=/usr/share/OVMF/OVMF_VARS.fd -drive format=raw,file=edk2/BootloaderPkg/disk.img,if=virtio

几秒钟后您应该会看到 UEFI shell 出现。然后输入 

fs0:
，然后输入 
Bootloader.efi
。这将更改目录，然后启动您的 EFI 应用程序。

我很惊讶您在构建 EDK2 方面取得了如此大的进展。

这是我必须做的来构建它：

  • 确保安装了以下软件包：gcc-c++、nasm、libuuid-devel、acpica-tools
  • 确保您使用的是 GCC bdf 链接器，即 /usr/bin/ld.bfd，而不是 gold 链接器。

作为普通用户：

$ git clone https://github.com/tianocore/edk2.git
$ cd edk2
$ git submodule update --init
$ cd BaseTools
$ make

假设您成功构建了工具，接下来测试构建现有的 EDK2 包：

$ cd edk2
$ . ./edksetup.sh
$ build -p MdeModulePkg/MdeModulePkg.dsc -t GCC5 -a X64
...
- Done -
Build end time: 19:36:56, Sep.04 2020
Build total time: 00:02:41
$

如果 

MdeModulePkg
成功构建，那么您就可以使用 EDK2 构建您的第一个 UEFI 应用程序了。
