网上关于mingw编译dcmtk的文章太少，不方便查阅，期间遇到各种问题。特意将整个编译过程记录下来。为了保证所有编译出来的文件方便我在Qt5.5.0中使用，将所有的dcmtk依赖的外部库下载下来并进行编译。整个编译过程如下。注，除msys外，其余所有依赖库，均在此处下载：http://www.dcmtk.org/dcmtk.php.en，所有安装包，依赖库，均解压到d盘下；
Msys
版本：1.0.11
下载地址：http://download.csdn.net/detail/syz9011/9246179
一路安装下去即可
ZLIB
版本：1.2.5
新建文件夹libzlib，并将zlib解压后放置在libzlib文件夹中，同时，再在内部新建文件夹out，方便讲编译出来的文件提取安装到out中。（即源码路径为：d:/libzlib/zlib-1.2.5。输入文件路径为d:/libzlib/out）
在zlib文件夹中打开命令行，输入：
copy win32\makefile.gcc makefile.gcc
mingw32-make -f makefile.gcc
1
2
目前为止，暂未编译通过，每次生成dll都会失败，但因为不需要dll，只需要动态库，故暂时未管。将zonf.h提取到out中的include文件夹中，将libz.a放到out中的lib文件夹中。

LIBPNG
版本：1.4.3
新建文件夹libpng，并将libpng-1.4.3解压后放置在libpng文件夹中，同时，再在内部新建文件夹out，方便讲编译出来的文件提取安装到out中.（即源码路径为：d:/libpng/libpng-1.4.3。输入文件路径为d:/libpng/out）
打开scripts/makefile.gcc设置zlib路径：
ZLIBINC = d:/libzlib/out
ZLIBLIB = d:/libzlib/out
1
2
运行msys.bat，并cd到libpng-1.4.3路径中，输入如下：
./configure --prefix=d:/libpng/out
make
make install
1
2
3

LIBJPEG
因编译LIBTIFF需要依赖于LIBJPG，故需要编译此库
下载地址：http://www.ijg.org/files/jpegsr9a.zip
路径放置同上：
即源码路径为：d:/libjpeg/jpeg-9a。输入文件路径为d:/libjpeg/out
运行msys.bat，并cd到jpeg-9a路径中，输入如下：
./configure --prefix=d:/libpng/out
1
打开jconfig.h，增加以下定义：
#define HAVE_PROTOTYPES 1
1
保存，然后继续在msys.bat中输入如下：
make
make install
1
2

LIBTIFF
路径放置同上：
即源码路径为：d:/libtiff/tiff-3.9.4。输入文件路径为d:/libtiff/out
运行msys.bat，并cd到tiff-3.9.4路径中，输入如下：
./configure --with-zlib-include-dir=d:/libzlib/out --with-zlib-lib-dir=d:/libzlib/out --with-jpeg-include-dir=d:/libjpeg/out/include --with-jpeg-lib-dir=d:/libjpeg/out/lib --prefix=d:/libtiff/out
make
make install
1
2
3
注意，编译完成后，需要将libjpeg中的libjpeg.dll.a拷贝到libtiff的out的lib文件夹下，否则dcmtk编译会出错。

LIBICONV
路径放置同上：
即源码路径为：d:/libiconv/libiconv-1.13.1。输入文件路径为d:/libiconv/out
运行msys.bat，并cd到libiconv-1.13.1路径中，输入如下：
./configure --prefix=d:/libiconv/out
make
make install
1
2
3
编译后的下载链接：http://download.csdn.net/detail/syz9011/9247017
openssl
路径放置同上：
即源码路径为：d:/libopenssl/openssl-1.0.0c。输入文件路径为d:/libopenssl/out
此时，进入到d:/libopenssl/openssl-1.0.0c/test文件夹下，打开md2test.c，将内容从 dummytest.c 改为 #include “dummytest.c”,同样的还有rc5test.c以及jpaketest.c
运行msys.bat，并cd到openssl-1.0.0c路径中，输入如下：
./config shared --prefix=d:/libopenssl/out
make depend
make
make test
make install
1
2
3
4
5
编译后的下载链接：http://download.csdn.net/detail/syz9011/9261499
LIBXML
路径放置同上：
即源码路径为：d:/libxml/libxml2-2.7.7。输入文件路径为d:/libxml/out
运行msys.bat，并cd到libxml2-2.7.7路径中，输入如下：
./configure --prefix=d:/libxml/out
make
make install
1
2
3
注意，编译完成之后，需要到out路径下，打开include文件夹，并将libxml2文件夹内的libxml文件夹拷贝到include文件夹下面，否则之后编译DCMTK时，会出现找不到libxml头文件的情况。另外，将libiconv中编译出来的.dll.a文件拷贝到libxml中的out中的lib文件夹下
ps:mingw4.8版本make过程中会报错，undefined reference _imp__xmlfree。mingw4.9.2不会

DCMTK
路径放置同上：
即源码路径为：d:/dcmtk/dcmtk-3.6.1_20150924。输入文件路径为d:/dcmtk/out。编译输出路径为d:/dcmtk/gcc.
打开源码路径下CMake文件夹下的3rdparty.cmake，并做如下更改：
