2019-07-08 又一次更新
这次是为了升级到可以支持TLS1.3,所以又要编译OpenSSL,再次记录一下。
- 不能再用VS2005编译了,我怎么试验也不行。手头现成的VS是2012所以就以它为示例
- 首先就是要安装ActivePerl
- 启动 Developer Command Prompt For VS2012
- 然后运行如下命令
> perl Configure VC-WIN32 #生成Makefile > nmake #直接编译,以前会调用ms\do_ms之类的,新的OpenSSL中没有这东西了
这样就OK了
这之后在把编译好的库放入原来的工程中编译的时候又出问题了,主要是编译选项的Runtime Library:MDD MTD MD MT这个有冲突。那么这种冲突如何解决呢?以MD改MT为例
- 找到目录下生成的Makefile
- 搜索MD (CFLAGS中的),找到后改成MT
- 重新 nmake
就可以了
下面那一大堆都是自己以前的记录,但是前几天在翻看OpenSSL的源代码的时候突然想调试一下,所以就想着怎么用编出给VS调试用的OpenSSL Library。虽然后来没有实现自己的想法,不过找到一个不错的网站,上面有已经编译好的OpenSSL的Library还有编译方法。相比我的记录就更加全面了,所以记录一下。
Building OpenSSL with Visual Studio
@1
- Uncompress the openssl-1.0.1c.tar.gz, For example at C:\openssl-1.0.1c
- Install the ActivePerl
- Use the VS2005 Command Prompt
Start->All Programs->Microsoft Vistual Studio 2005->Visual Studio Tools->Visual Studio 2005 Command Prompt
> perl configure VC-WIN32
> ms\do_ms
If you want to build the dlls, input:
> nmake -f ms\ntdll.mak
if you want to build the libs, input:
> nmake -f ms\nt.mak
- when the compiling is finished, you can find the dll&exe in
folder or you can find the lib&exe in folder. - If you want use openssl api in you project, please include the
folder in you project.

The all asm SHOULD use NASM to build, so use NASM to replace the MS:
- Install the NASM, download from http://www.nasm.us/
- Add the NASM path to the $PATH
Build the OpenSSL:
> perl configure VC-WIN32
> ms\do_nasm
> nmake -f ms\nt.mak
