用MinGW编译openssl

1. Download
http://openssl.org/source/
Get openssl-1.0.0.tar.gz.
http://www.activestate.com/activeperl/downloads
Get ActivePerl msi installer.
http://sourceforge.net/projects/mingw/files/
Get msysCORE-1.0.14-1-msys-1.0.14-bin.tar.lzma and gzip-1.3.12-1-msys-1.0.11-bin.tar.lzma. Unpack to C:/MSYS.

Follow C:/MSYS/share/doc/MSYS/msysCORE-1.0.14-1-msys-RELEASE_NOTES.txt and get packages that meet the “Build requirements”, unpack to MSYS or MinGW directory accordingly.

2. Prepare

Install ActivePerl.

Run C:/MSYS/postinstall/pi.bat for MSYS post installation.

Run C:/MSYS/msys.bat.

因为openssl-1.0.0.tar.gz中包含了符号链接文件，如果用7-Zip解压可能会出现大小为0字节的文件，所以应在MSYS中解压：

cd /d/download/tool/dev

tar -xvzf openssl-1.0.0.tar.gz

修改cms-test.pl中影响后续"make test"步骤的问题。

3. Compile

cd openssl-1.0.0

./config -t

./config threads shared no-capieng

make depend

make

make test

make install

因为目前MinGW版本的wincrypt.h头文件还未同步某些Windows CryptoAPI新特性，所以要在config时使用no-capieng选项防止编译相关代码。另外，要注意config时不要使用--prefix选项，避免因为MSYS与Windows的目录结构不同导致问题。
