如何使用 Visual Studio 2017 在 Windows 上构建 OpenSSL？

Question

我正在尝试使用 OpenSSL，但我被困在编译步骤上。 OpenSSL 项目的文档非常不友好（糟糕）。

如何使用 Visual Studio 2017 在 Windows 上构建最新的 OpenSSL 版本是否有任何实际帮助？

我在 OpenSSL 官方网站上没有找到任何有用的信息。是的，网上有很多关于OpenSSL编译的帖子，但是都已经过时了。

Answer 1

我没有使用过 VS2017 而是以前的版本。我想它是一样的。请注意，以下说明适用于 OpenSSL 1.1.0 或更高版本。它们不适用于 OpenSSL 1.0.2。简而言之，步骤是：

1. 安装 Perl（ActiveState 或 Strawberry）

[编辑，请参阅下面的（kritzel_sw）评论：我强烈建议使用草莓）]

1. 安装 NASM

2. 确保 Perl 和 NASM 都在您的 %PATH% 上

3. 使用管理权限启动 Visual Studio 开发人员命令提示符（如果您正在构建 32 位 OpenSSL，请确保使用 32 位命令提示符，如果您正在构建 64 位 OpenSSL，请确保使用 64 位命令提示符）

4. 从 OpenSSL 源目录的根目录输入 perl Configure VC-WIN32 如果您想要 32 位 OpenSSL 或 perl Configure VC-WIN64A 如果您想要 64 位 OpenSSL

5. 输入 nmake

6. 输入 nmake test

7. 输入 nmake install

[编辑，除非您更改配置中的目标目录，否则 nmake install 需要管理员权限。所以必须以管理员身份启动 VC 命令提示符才能完成这最后一步]

如果在任何阶段出现任何问题，请检查 INSTALL 文件和 NOTES.WIN 文件。

The Quantum Physicist python 脚本的修改版

它可以编译 OpenSSL 1.0.x 或 OpenSSL 1.1.x

它可以与包含多个版本的 Visual Studio ²⁰¹⁷⁄₂₀₁₉ 一起编译。

1）创建文件：CompileOpenSSL.py

 import os
import os.path
from subprocess import call
import shutil
import sys
import re
import argparse

# args
parser = argparse.ArgumentParser()
parser.add_argument("-f", "--filename", help="First argument must be the tar.gz file of OpenSSL source", required=True)
parser.add_argument("-a", "--arch", help="Second argument must be x86 or amd64", required=True)
parser.add_argument("-v", "--vs_version", help="Visual Studio version (eg:90, 140, 150)", required=True)
parser.set_defaults(writeVersionInfos=False)
args = parser.parse_args()

compile_flags = "-no-asm"
#compile_flags = "-no-asm -no-shared"

openssl_32_flag = "VC-WIN32"
openssl_64_flag = "VC-WIN64A"

working_dir = os.getcwd()

dirname  = args.filename.replace(".tar.gz","")

src_32_suffix = "_" + "vs" + args.vs_version + "_32"
src_64_suffix = "_" + "vs" + args.vs_version + "_64"

vs_tools_env_var = "VS" + args.vs_version + "COMNTOOLS"

if args.arch != "x86" and args.arch != "amd64":
    print("Second argument must be x86 or amd64")
    exit(1)

if not bool(re.match("(openssl-){1}(\d)+(.)(\d)+(.)(\d)+(\w)+(.tar.gz)",args.filename)):
    print("The file given doesn't seem to be an openssl source file. It must be in the form: openssl-x.y.zw.tar.gz")
    exit(1)

call("7z x -y " + args.filename) #extract the .gz file

dirname_src_32 = dirname + src_32_suffix
dirname_src_64 = dirname + src_64_suffix
dirname_bin_32 = dirname + src_32_suffix + "_build"
dirname_bin_64 = dirname + src_64_suffix + "_build"

openssl_tar_file = args.filename[0:-3]

if args.arch == "x86":

#delete previous directories
    shutil.rmtree(os.getcwd()+'/'+dirname, ignore_errors=True)
    shutil.rmtree(os.getcwd()+'/'+dirname_src_32, ignore_errors=True)

#extract tar file for 32

    call("7z x -y " + openssl_tar_file)
    os.rename(dirname, dirname_src_32)

#Compile 32
    os.chdir(dirname_src_32)

    print("perl Configure " + openssl_32_flag + " --prefix=" + os.path.join(working_dir,dirname_bin_32) + " " + compile_flags)
    call("perl Configure " + openssl_32_flag + " --prefix=" + os.path.join(working_dir,dirname_bin_32) + " " + compile_flags,shell=True)

    if( os.path.exists("ms/do_ms.bat") ):
        call("ms\do_ms.bat",shell=True)
        print(os.getcwd())
        call("nmake -f ms/ntdll.mak",shell=True)
        call("nmake -f ms/ntdll.mak install",shell=True)
    else:
        call("nmake",shell=True)
        call("nmake test",shell=True)
        call("nmake install",shell=True)

    print("32-bit compilation complete.")

#Go back to base dir
os.chdir(working_dir)
################

if args.arch == "amd64":

#delete previous directories
    shutil.rmtree(os.getcwd()+'/'+dirname, ignore_errors=True)
    shutil.rmtree(os.getcwd()+'/'+dirname_src_64, ignore_errors=True)

#extract for 64
    call("7z x -y " + openssl_tar_file)
    os.rename(dirname, dirname_src_64)

#Compile 64
    os.chdir(dirname_src_64)

    call("perl Configure " + openssl_64_flag + " --prefix=" + os.path.join(working_dir,dirname_bin_64) + " " + compile_flags,shell=True)
    if( os.path.exists("ms\do_ms.bat") ):
        call("ms\do_win64a.bat",shell=True)
        call("nmake -f ms/ntdll.mak",shell=True)
        call("nmake -f ms/ntdll.mak install",shell=True)
    else:
        call("nmake",shell=True)
        call("nmake test",shell=True)
        call("nmake install",shell=True)

    print("64-bit compilation complete.")

#Go back to base dir
os.chdir(working_dir)
################

os.remove(openssl_tar_file)

2）创建文件：CompileOpenSSL_vs.cmd
