This posting is to help people to build OpenSSL 1.0.1 with Microsoft
Visual Studio. It may also indicate a required change to the build
instructions for Microsoft Visual Studio.
Summary:
----------
I found I needed to install the Windows SDK and manually configure my
build environment to successfully build OpenSSL 1.0.1
Details:
-------
I recently had to move my build machine to another PC, and I needed to
build OpenSSL 1.0.1.
I had installed MS Visual Studio 2005 on a Win XP system.
I followed the excellent build instructions in the INSTALL.W32 file. I
built from a Visual Studio 2005 Command Prompt window as I always do.
Unfortunately my first build failed in the link phase because it
couldn't find crypt32.lib.
On further investigation I found that crypt32.lib was in the Microsoft
SDK which I had to download and install on my build machine.
I trashed my build directory and unpacked a new one, so I could go
through the configure script with the installed SDK. I started a new
Visual Studio 2005 Command Prompt Window for the build. Unfortunately
the configure script did not find the SDK libraries and my build failed
in the same place.
So I manually modified the vsvars32.bat file that the "Visual Studio
Command Prompt" uses to load its environment variables. I added:
%Program Files%\Microsoft SDKs\Windows\7.0\Bin to PATH
%Program Files%\Microsoft SDKs\Windows\7.0\Include to INCLUDE
%Program Files%\Microsoft SDKs\Windows\7.0\Lib to LIB
(On my system this file can be found in %Program Files%\Microsoft Visual
Studio 8\Common7\Tools)
Again I trashed the build directory and unpacked a new one. I started a
new Visual Studio 2005 Command Prompt Window and went from the configure
phase right through to build and test. Everything worked beautifully.
All modules were built and all the tests passed successfully.
As I said, I hope this helps others and, if appropriate, the developers
might want to state the Microsoft SDK is a requirement for Visual Studio
builds.
Regards,
Jeremy
