我尝试过：



我添加了DCMTK静态库并在QT中包含路径并试图构建但是出错。



请帮助...

解决方案

未定义的引用错误告诉您没有将应用程序与包含对应函数的库链接（ s）。



您必须使用 LIBS 变量在Qt项目文件中添加库路径和名称。在那里，您可以使用 -L 指定其他路径，使用 -l <​​/ code>指定库名称（包含路径不用于库） ）：

 LIBS + = -L<路径到DCMTK-libraries = DCMTK_INSTALL_LIBDIR> -l< library-name> 

动态库示例：

 LIBS + = -L / usr / local / dcmtk12 -ldcmtk12_3.6.2 

静态库的示例：

 LIBS + = -L / usr / local / dcmtk12 -llibdcmtk12_3.6.2.a

What I have tried:

I was added DCMTK static library and include path in QT and tried to build but getting errors.

please help...

解决方案

The "undefined reference" error tells you that you did not link your application with the library containing the correspoding function(s).

You have to add the library path and name in your Qt project file using the LIBS variable. There you can specify additional pathes with -L and library names with -l (the include path is not used for libraries):

LIBS += -L<path-to-DCMTK-libraries = DCMTK_INSTALL_LIBDIR> -l<library-name>

Example for dynamic library:

LIBS += -L/usr/local/dcmtk12 -ldcmtk12_3.6.2

Example for static library:

LIBS += -L/usr/local/dcmtk12 -llibdcmtk12_3.6.2.a
