使用Openssl库的编译问题 [英] using Openssl library compilation issue
问题描述
你好编码员，
我正在尝试将一些DES加密功能从C ++ NewcamD项目转换为.NET，但是我需要一些帮助，因为它正在使用特定的DES转换，并且我想对其进行正确的测试. C ++使用额外的带有三重DES加密的OPENSSL库.我不需要任何套接字来进行测试，但是我需要加密/解密测试，因此我尝试用C ++创建简单的加密/解密项目，但编译失败，并出现一些错误:
错误5错误LNK2019:在函数专用:无效__thiscall cTripleDes :: SetOddParity(unsigned char *)"中引用了未解析的外部符号_DES_set_odd_parity(?SetOddParity @ cTripleDes @@ AAEXPAE @ Z)cTripleDes.obj NewCamD_test

该问题出现在我无法为OpenSSL配置的ActivePerl中.但是我确实发现在使用选项1将它们添加到项目中之后，提供的链接和错误列表上的lib文件现在似乎已经缩小了范围.

解决方案
您确定要链接到OpenSSL库吗?这些未解析的外部符号是OpenSSL函数...
选项1:
您需要将OpenSSL库添加到项目链接程序依赖项中:
连结器->输入->其他依赖项
选项2:
或者，您可以将其添加到您的cTripleDes.cpp文件中:
#pragma comment(lib，"ssleay32.lib")
#pragma comment(lib，"libeay32.lib")
如果使用选项2，请确保将这些lib文件添加到lib路径中的目录中.您可能应该使用选项1 ...，以便学习如何在项目中正确设置lib路径.
如果您没有OpenSSL库，请下载它们: http://www.openssl.org/related/binaries.html [^ ]
另外...请确保使用正确的运行时库 [ ^ ].从OpenSSL站点下载的库将包含每个运行时的库.
最好的祝福，

Hello coders,
I am trying to convert few DES encryption functions from C++ NewcamD project to .NET but I need some help as it is using specific DES convertion and I want test it properly. C++ uses extra OPENSSL library with Triple DES encryption. I don''t need any sockets for testing but I need encryption/decryption testing so I''ve tried to create simple encryption/decryption project in C++ but it fails on compilation with some errors:

Thanks David,
The problem appears in ActivePerl which I am unable to configure for OpenSSL. But I did found lib files on provided link and error list now seems to be narrowed down after adding them to the project using Option 1:
Error 4 error LNK2019: unresolved external symbol ___security_cookie referenced in function "protected: unsigned char const * __thiscall cTripleDes::Encrypt(unsigned char const *,int,unsigned char *)" (?Encrypt@cTripleDes@@IAEPBEPBEHPAE@Z) cTripleDes.obj NewCamD_test
Error 5 error LNK2019: unresolved external symbol @__security_check_cookie@4 referenced in function "protected: unsigned char const * __thiscall cTripleDes::Encrypt(unsigned char const *,int,unsigned char *)" (?Encrypt@cTripleDes@@IAEPBEPBEHPAE@Z) cTripleDes.obj NewCamD_test
Error 6 fatal error LNK1120: 2 unresolved externals C:\PROJECTS\C++\NewCamD_test\Debug\NewCamD_test.exe 1 NewCamD_test
解决方案 Are you sure that you are linking with the OpenSSL library? Those unresolved external symbols are OpenSSL functions...
Option 1:
You need to add the OpenSSL libs to your project linker dependencies:
Linker -> Input -> Additional Dependencies
Option 2:
Alternatively you could add this to your cTripleDes.cpp file:
#pragma comment(lib, "ssleay32.lib")
#pragma comment(lib, "libeay32.lib")
If you use option 2 make sure that you add those lib files to the directory in your lib path. You should probably use option 1... so you learn how to correctly setup lib paths within your projects.
If you do not have the OpenSSL libraries then download them: http://www.openssl.org/related/binaries.html[^]
Also... make sure that you use the correct Run-Time Library[^]. The libs downloaded from the OpenSSL site will contain a library for each run-time.
Best Wishes,
