DCMTK3.6.1(MD支持库)安装说明

【前言】

最近，因为需要开发DICOM网管模块，必须使用DCMTK的DcmNet模块。但是DCMTK3.6.0在DcmNet模块中只提供两个实验阶段的网络类DcmSCU和DcmSCP。而且他们并没有完全实现DICOM的C-Echo、C-Find、C-Get、C-Move和C-store操作。只实现了C-Echo和C-Find操作。

调研了一番，发现DCMTK小组在最新的snapshot版本中（DCMTK3.6.1 2012-08-31），已经实现了DICOM全部操作。而且他们官方论坛中，开发人员在回答疑问时候，针对3.6.0中出现的bug等问题。他们也是鼓励大家直接用最新的DCMTK3.6.1.

当然他们也建议大家自己去通过底层代码实现DcmScu的其他的操作。不过对于我们这种新手来讲确实很困难，而且关键问题在后期的3.6.1版本的代码变化很大。我们自己手写的，以后不方便兼容。

所以最终我还是下载了最新的DCMTK3.6.1-20120831，但是他有一个问题，目前只支持在linux上编译和运行。windows环境，他们并没有提供支持库。于是又让我踌躇了一番，自己也手动试着基于3.6.0写了点代码，但是真的是超级难。最终下定决心在win7上编译3.6.1，并利用DCMTK3.6.0的support（MD）Library。在DCMTK官方论坛开发人员的帮助下，最终编译成功。也实现DcmScu的例子网络访问。

【开发环境】

操作系统：win7 32bit

开发工具：VS2008 + Qt4.7.4

1、DCMTK： DCMTK3.6.120120831

2、DCMTK support libraries for windows： dcmtk-3.6.0-win32-i386-support_MD.zip

3、CMake：cmake-2.8.9-win32-x86.exe

目前我的Qt项目都是基于MD/MDd的运行时库。

【安装过程】

1、将支持库中的相应lib文件，include文件，bin文件拷贝到VS2008安装目录的相应文件夹下。

2、CMake编译

A、设置source code 路径: D:\DCMTK\dcmtk-3.6.1_20120831

B、设置binaries路径： D:\DCMTK\DCMTK-bin

C、选择Configure：visual studio 9 2008

D、等待configure完毕后，会有很多find和not find，无所谓。

E、选中Advanced单选框，然后在红色区域设置：

set DCMTK_OVERWRITE_WIN32_COMPILER_FLAG = OFF；（不选中，这样可以使生成项目运行时库都是MD/MDd，而不是默认的MT/MTd）

set "DCMTK_WITH_ICONV" to "ON" （选中)

set "DCMTK_WITH_OPENSSL" to "ON"（选中)

set "DCMTK_WITH_PNG" to "ON" （选中)

set "DCMTK_WITH_TIFF" to "ON" （选中)

set "DCMTK_WITH_XML" to "ON" （选中)

set "DCMTK_WITH_ZLIB" to "ON" （选中)

F、点击Generate，很快就完成。这时候VS项目源码已经生成。

3、VS2008编译项目源码

A、用VS打开 D:\DCMTK\DCMTK-bin\DCMTK.sln

B、点击Build->Batch Build，选择ALL_BUILD项目的debug版，点击右边的Build。耐心等待。会有很多个warning，应该是由字符编码不统一引起的。最后会看到82个编译 成功，0个失败。

C、再选择Build->Batch Build，这次选择INSTALL项目的debug版本，点击右边的Build。最后会显示1个工程编译成功，这时在你选择的安装目录下（默认是C:\Program Files\DCMTK）就会有lib,bin,include,etc,share文件夹，里面就是之后写程序做医学图像处理所需要的库文件了

4、代码测试

F． Debug，ok，编译工程，运行成功。访问了www.dicomserver.co.uk的DICOM服务器。

源代码如下：

The code uses the public DICOM server at www.dicomserver.co.uk which is offered by Dave Harvey (MedicalObjects). There are also logs you can check at the server in order to debug your application.

#include "dcmtk/dcmnet/scu.h"     /* Covers most common dcmdata classes */ 
 
 
class DcmTestSCU : public DcmSCU 
{ 
 
public: 
 
  DcmTestSCU()  {} 
  ~DcmTestSCU() {} 
 
}; 
 
#endif // TESTSCU_H

DCMTK3.6.1编译失败总结

针对DCMTK3.6.1 编译的错误总结：

1、完全默认CMake配置， DCMTK编译成功。但无支持库externallibraries (OpenSSL, zlib, libtiff, libpng, libxml2 and libiconv)

结果：如果不加支持库，运行网上例子，肯定出错。1>Linking...1> LINK : fatal error LNK1181: cannot open input file ‘zlib.lib‘

2、设置了MD支持库，在VC里配置好文件，手动修改CMakeList.txt为MD/MDd。会出现如下错误：warning LNK4098: defaultlib ‘MSVCRTD‘ conflicts with use of other libs; use等运行时库冲突错误。

3、按照DCMTK官方编译方法失败。官方配置CMake属性，加上3.6.0MD支持库，

缺少libiconv的编译后的支持库。

最后还是按照如上方法，完全实现DCMTK3.6.1在win7上的编译。
