Openssl-1.1.1-pre1 Windows environment Compilation

Scene
VS2015 compiling Openssl-1.1.1-pre1

Tools
Nasm-2.14rc0-installer-x64.exe
Activeperl-5.24.3.2404-mswin32-x64-404865.exe
Openssl-1.1.1-pre1.tar.gz

Environment variables
C:\Program files\nasm (add assembler path)
C:\Program Files (x86) \microsoft Visual Studio 14.0\vc\bin (VS2015 compilation path)

Operation
1) Perl Configure Vc-win32 [no-shared] [no-asm] [no-tests] [--debug]--prefix=d:\openssllib
Vc-win32: Can be modified as required to 64 bits, etc., no-shared to compile a static library, not add the default compiler is a dynamic library, no-tests do not need to tests function, if only the OpenSSL can be added to the library, otherwise there may be many errors caused by the compilation but --debug to compile the debug version, the release version is not compiled by default.
2) NMAKE, after compiling the pass, then nmake install to the directory specified by--prefix=.
3) If you want to compile multiple versions (RELEASE,DEBUG), it is best to first nmake clean, then repeat the 3rd step.
Attention:
The runtime Library of the 1.VS project should be selected to match the compiled OpenSSL library, especially the dynamic library, which might otherwise compile
2. If you need to use a static library, you may also need to add a ws2_32.lib,crypt32.lib library if you compile the error such as LNK2019.
3.NASM Assembler does not install the following error
C:\users\admin\downloads\openssl-1.1.1-pre1>perl Configure Vc-win32
Using Implicit seed configuration
Configuring OpenSSL version 1.1.1-pre1 (0x10101001l) for Vc-win32
NASM not found-please read INSTALL and NOTES. WIN for further details
4It looks like you don ' t has either nmake.exe or Dmake.exe on your path error solution
It looks like you don ' t has either nmake.exe or Dmake.exe on your PATH,
Able to execute the commands from a Makefile. You can
Install Dmake.exe with the Perl package Manager by running:
PPM Install Dmake
Resolution: Perform PPM install dmake, installing Dmake.
Description: PPM is a Perl graphical package management tool, Dmake is a tool similar to GNU make, supporting cross-platform
Current installation VS2015, search to Nmake.exe, then execute Vcvarsall.bat, and add the NMAKE path to VS to environment variable or there is a problem
