How to build OpenSSL on Windows.
================================

Requirements.
	* Perl Installation    : http://www.activestate.com/activeperl/downloads
	* OpenSSL source code  : http://www.openssl.org/source/
	* C compiler


How to build OpenSSL with VisualStudio  
======================================
Tutorial :http://developer.covenanteyes.com/building-openssl-for-visual-studio/

Building OpenSSL for Visual Studio on Windows:

	Visual Studio 2010 (this will likely work with older versions as well).

Setting up for the build

Unzip the OpenSSL source code into two different folders, one for the 32-bit build and one for the 64-bit build. 
So, for example, you might end up with C:\openssl-src-32 and C:\openssl-src-64.

Building the 32-bit static libraries

Open the Visual Studio Command Prompt (2010)5.
cd to your OpenSSL source folder for 32-bit (e.g. cd C:\openssl-src-32).
Run the following: 

1: perl Configure VC-WIN32 --prefix=C:\Build-OpenSSL-VC-32
2: ms\do_ms
3: nmake -f ms\nt.mak 
4: nmake -f ms\nt.mak install

Your outputs will be in C:\Build-OpenSSL-VC-32.

Building the 32-bit static libraries with debug symbols

These steps will embed the debug symbols directly into the .lib files. Don’t expect to see any .pdb files.

Open the Visual Studio Command Prompt (2010).
cd to your OpenSSL source folder for 32-bit (e.g. cd C:\openssl-src-32).
Run the following:


1: perl Configure debug-VC-WIN32 --prefix=C:\Build-OpenSSL-VC-32-dbg
2: ms\do_ms

In a text editor (like Notepad), open ms\nt.mak and replace all occurrences of /Zi with /Z7. There should be three replacements.
Run the following:


1: nmake -f ms\nt.mak
2: nmake -f ms\nt.mak install
Your outputs will be in C:\Build-OpenSSL-VC-32-dbg. Make sure you rename them to something like libeay32-debug.lib and ssleay32-debug.lib.

Building the 64-bit static libraries

Open the Visual Studio x64 Win64 Command Prompt (2010) (in the Start menu).
cd to your OpenSSL source folder for 64-bit (e.g. cd C:\openssl-src-64).
Run the following:

1: perl Configure VC-WIN64A --prefix=C:\Build-OpenSSL-VC-64
2: ms\do_win64a
3: nmake -f ms\nt.mak
4: nmake -f ms\nt.mak install

Your outputs will be in C:\Build-OpenSSL-VC-64.

Note: The outputs of the 64-bit build are still named libeay32.lib and ssleay32.lib. You’ll have to rename them more sensibly yourself.

Building the 64-bit static libraries with debug symbols

These steps will embed the debug symbols directly into the .lib files. Don’t expect to see any .pdb files.

Open the Visual Studio x64 Win64 Command Prompt (2010).
cd to your OpenSSL source folder for 64-bit (e.g. cd C:\openssl-src-64).
Run the following:


1: perl Configure debug-VC-WIN64A --prefix=C:\Build-OpenSSL-VC-64-dbg
2: ms\do_win64a

In a text editor (like Notepad), open ms\nt.mak and replace all occurrences of /Zi with /Z7 except on the line starting with ASM. There should be two replacements. 
Run the following:



1: nmake -f ms\nt.mak
2: nmake -f ms\nt.mak install
Your outputs will be in C:\Build-OpenSSL-VC-64-dbg. Make sure you rename them to something like libeay64-debug.lib and ssleay64-debug.lib



Building OpenSSL with MingGW
============================
Tutorial: https://github.com/freelan-developers/freelan-buildtools/blob/6ffc5f758ab1f240fe1f052e77e7a5a814578184/INSTALL.md

Windows 32/64 bits - MinGW

You must run these commands from a MSys console.

For 32 bits:

	perl Configure mingw no-shared no-asm --prefix=/c/OpenSSL

For 64 bits:

	perl Configure mingw64 no-shared no-asm --prefix=/C/OpenSSL-x64

Then:

	make depend

	make

	make install


The make depend line is only needed on the most recent OpenSSL version if you specified any of the no-... options.

Note that this will compile OpenSSL in static mode.

If at some point you get a "make (e=2):" error, ensure you don't have another "make.exe" in your PATH or just type /bin/make instead of make.
