VS2013 compiling OpenSSL under Windows environment

OpenSSL version: 1.0.2H

Compiler: MSVC (VS2013)

Need to prepare the tool: Perl.

Perl download for Windows environment Please poke here: Http://www.activestate.com/activeperl

Open the VS2013 x86 Native command Prompt (compiled by the 32-bit version) and switch to the SSL solution path:

Perl Configure vc-win32 --prefix=C:\build-openssl-vc-32 #rel Ease version with Vc-win32 Debug version with Debug-vc-win32

ms\do_ms.bat nmake -F MS\NT. Mak nmake -F MS\NT. Mak Install

Run the command above, resulting in an error:

ssembling: tmp32\sha1-586.asm

tmp32\sha1-586.asm(1432) : error A2070:invalid instruction operands

tmp32\sha1-586.asm(1576) : error A2070:invalid instruction operands

Then the reason traced here: https://github.com/openssl/openssl/issues/169

See after the reason is that the original Do_ms.bat compilation is used MASM compiler, MASM compile sha1-586.asm file error. Issue above someone said do not use MASM compile, replace NASM compile,

Then I downloaded the NASM from NASM's official website, with the environment variable, run the following command:

Perl Configure vc-win32 --prefix=C:\build-openssl-vc-32 #rel Ease version with Vc-win32 Debug version with Debug-vc-win32

ms\do_nasm.bat nmake -F MS\NT. Mak nmake -F MS\NT. Mak Install

Then you can build it successfully.
