RE: Building ssh on Windows

["Zeldin, Boris" <boris.zeldin@xxxxxxx>]

I would like to report my experience building SSH on Windows.


1. It is important to have the right version of OpenSSL installed. By chance I had previous version 0.9.8h on my machine. Its include and lib files do not compile. 

2. The Prebuilt ZLIB library for versions 1.2.5 and 1.2.7 does not work
	(http://www.winimage.com/zLibDll/zlib125dll.zip)
Linker complains on missing symbols. I had to compile LIBSSH against ZLIB version 1.2.3 
	(http://gnuwin32.sourceforge.net/packages/zlib.htm)
At the same time, I had to overwrite include files of v 1.2.3 with include files of v.1.2.5

After resolving issues with the external libraries, the build proceeds effortlessly. 

Also, I think that libssh.org should put a distributable pre-built version of the Windows library. The current library posted on the website cannot be distributed to the end users. It contains a reference to the non-distributable library MSVCR100D.DLL.

After reinstalling OpenSSL and fixing my registry, I was able to fix most of the build problem. 
Still my build complains on missing symbols related to ZLIB

1>gzip.obj : error LNK2019: unresolved external symbol _deflate referenced in function _gzip_compress
1>gzip.obj : error LNK2019: unresolved external symbol _deflateInit_ referenced in function _initcompress
1>gzip.obj : error LNK2019: unresolved external symbol _inflate referenced in function _gzip_decompress
1>gzip.obj : error LNK2019: unresolved external symbol _inflateInit_ referenced in function _initdecompress
1>wrapper.obj : error LNK2019: unresolved external symbol _inflateEnd referenced in function _crypto_free
1>wrapper.obj : error LNK2019: unresolved external symbol _deflateEnd referenced in function _crypto_free

Any suggestion will be greatly appreciated.

I download zlib and ssl from here:

http://www.winimage.com/zLibDll/
http://www.winimage.com/zLibDll/zlib125dll.zip

http://slproweb.com/products/Win32OpenSSL.html
http://slproweb.com/download/Win32OpenSSL-1_0_1c.exe

I install them both in C:\Program Files


Then I start cmake, select Visual Studio or MinGW and click on configure. 
OpenSSL and ZLIB are automatically found.

Then I call make or click on compile in VS. I'm not a Windows user but it 
can't be easier. I wonder what all you guys are doing to not get it working.
