Question

我看过有关使用自定义OpenSSL版本编译OpenVPN的帖子。我尝试过它们，并且完美地使用了最新版本的OpenVPN-2.3.11和OpenSSL 1.0.2h。但是在所有这些情况下，OpenSSL的源代码都可用。

我的问题是，如果我没有OpenSSL的任何来源以及某些自定义OpenSSL的预编译二进制文件，该怎么办？如何用这样的二进制文件编译OpenVPN。很抱歉，如果这个问题已被多次回答 - 我无法找到问题的答案。

我的问题是如果我没有OpenSSL的任何来源以及某些自定义OpenSSL的预编译二进制文件。如何使用这些二进制文件编译OpenVPN。

您无法针对[private] OpenSSL构建OpenVPN，因为您需要OpenSSL头文件。

您可能能够使用strings确定[私有] OpenSSL库的版本，然后从OpenSSL download page上的OpenSSL包中获取标头（be如果需要，一定要访问/source/old。以下是从源代码构建并在本地安装的OpenSSL 1.0.2的示例。

如果您想要复制丢失的头文件，请确保运行./config以生成openssl/opensslconf.h和openssl/bn.h。

尝试复制丢失的标头有点冒险，而且真的想要[私有] OpenSSL库中的openssl/opensslconf.h和openssl/bn.h。
