errors in linking dcmtk libraries!

[sivasankari]

hello everybody, i try to link dcmtk with my code(DicomData) .
My CmakeLists.txt looks like this.

Aren't you compiling under Linux? In a previous thread you said so and from the command line dumps you provide it is kind of obvious.

If you are compiling under Linux, please note the following remark from the INSTALL file: "On Windows platforms (and only on Windows platforms!), the CMake utility can be used to turn the support for the above mentioned external libraries (OpenSSL, zlib, libtiff, libpng and libxml2) on or off manually (libwrap is currently not supported on Windows platforms)."

So the CMakeLists.txt files that come with DCMTK are not meant to be used under Linux. They are meant to be used on Windows Systems only. In fact, we have never tested compiling DCMTK based on CMake on any other platform but Windows, so we cannot help you in this respect.

How to compile DCMTK on Linux is thoroughly described in the INSTALL file. Make sure you have read and understood this file.

[sivasankari]

I have NOT used the Cmake to compile dcmtk on LINUX. Instead,
I have compiled the dcmtk files as per the instructions given in the INSTALL file.
(./configure
make install)

I am getting the problem and the above-said errors when I link those dcmtk libraries with my own application DicomData, using Cmake under LINUX.


Please help me with needed solution

[Marco Eichelberg]

On Linux, the link order of libraries is significant. Possibly you are not linking them in the correct order (e.g. -ldcmnet needs to be specified before -ldcmdata and this must be specified before -lofstd). A complete overview of library dependencies is provided in FAQ #27.

[sivasankari]

Thanks for your suggestion. It worked out well. But still i am getting few errors. I have arranged the dcmtk libraries in the order as given in DCMTK forum.
Now my cmakelists.txt look like this.

You are not linking all system libraries needed. In this case, -lpthread is missing. See config/Makefile.def for the various system libraries that DCMTK needs on your particular platform and configuration.
