    13 How to build openssl library for MinGW ?

    14 				

    15 1)Download the source code for openssl 9.7b version from http://www.openssl.org/ openssl-0.9.7b.tar.gz (currently we support 9.7b)

    16 

    17 2) 	untar it using  tar -zxvf openssl-0.9.7b.tar.gz

    18 

    19 3)	release version :

    20 	run ms/mingw32.bat in cygwin : It will generate  libcrypto.a in /out directory, which is a static version (Release) of openssl.

    21 

    22 4)	debug version :

    23 

    24 	a)	replace  line  " perl util/mk1mf.pl gaswin  Mingw32 >ms/mingw32a.mak "  with "perl util/mk1mf.pl gaswin debug Mingw32 >ms/mingw32a.mak"

    25 	b)	run ms/mingw32.bat in cygwin : it will generate libcrypto.a in /out.dbg directory which is a static version (Debug) of openssl.
