在Google上搜了一下opensc的简介，没有，算了还是自己说吧。
opensc官方网站
http://www.opensc-project.org/工程简介：对于智能卡的访问，opensc工程提供了一套库和工具。opensc重点放在了卡片的密码操作，推进卡片的应用如邮件加密、认证和签名。opensc实现了PKCS#11的API以便支持Mozilla FireFox（浏览器）和Thunderbird（邮件客户端）能使用它。opensc实现了PKCS#15标准以便兼容所有的应用。
opensc支持以下卡片：
National ID Cards
Smart Cards
USB Tokens
二、编译环境
操作系统：Windows XP SP3
开发工具：vistual studio 2003 sp1
代码：
opensc-0.11.6.tar.gz库：openssl 0.9.7e.tar.gz、
libtool-1.5.26-bin.zip三、编译过程
libtool：把zip包解压至c:\（或者别的目录）下
openssl：把tar.gz包解压至c:\下，编译之，步骤略（google上有很多在windows下编译openssl的例子）
opensc：把tar.gz包解压至c:\下，编辑 win32/Make.rules.mak。下面贴出编辑好的文件：
# Note: these instructions obsolete the instructions in opensc.html# You first need to download the gnuwin32 libtool (e.g. the "Binaries" and "Developer
# files" from http://gnuwin32.sourceforge.net/packages/libtool.htm)
# Then fill in the directory path to ltdl.h on the LIBLTDL_INCL line below, preceeded
# by an "/I"; and fill in the path to the libltdl.lib on the LIBLTDL_LIB line below.
# Then you can build this OpenSC package; and afterwards you'll need to copy the
# libltdl3.dll somewhere on your execution path.
LIBLTDL_INCL = /IC:\libtool-1.5.26-bin\include # E.g. /IC:\libtool-1.5.8-lib\include （这里改成你自己的路径，我的是c盘）
LIBLTDL_LIB = C:\libtool-1.5.26-bin\lib\ltdl.lib # E.g. C:\libtool-1.5.8-lib\lib\libltdl.lib（这里改成你自己的路径，我的是c盘）

# - set the OPENSSL_LIB below to your openssl lib file
OPENSSL_DEF = /DENABLE_OPENSSL #把这个选项打开，源代码中使用了openssl，不然会报错
!IF "$(OPENSSL_DEF)" == "/DENABLE_OPENSSL"
OPENSSL_INCL_DIR = /IE:\软件\加密库\openssl\openssl-0.9.7c\include #改这里的路径
OPENSSL_LIB = E:\软件\加密库\openssl\openssl-0.9.7c\out32dll\Debug\libeay32.lib #指向编译好的libeay32.lib

# - set the ZLIB_LIB below to your zlib lib file
#ZLIB_DEF = /DENABLE_ZLIB
!IF "$(ZLIB_DEF)" == "/DENABLE_ZLIB"
ZLIB_INCL_DIR = /IC:\ZLIB\INCLUDE
ZLIB_LIB = C:\ZLIB\LIB\zlib.lib
OPENSC_FEATURES = $(OPENSC_FEATURES) zlib

打开vistudio studio .net 2003 command prompt 窗口，然后在opensc根目录下执行 nmake -f Makefile.mak，编译成功！（文/adylee 出处/博客园）
