[Dcmlib] Undefined Symbols error - GDCM::Sorter

[Dr Nick Patterson]

Hi,
  I am using GDCM in a project that I am working on which handles DICOM images. I have been successfully developing this on Ubuntu linux, but recently when porting over to MacOSX (Mavericks) I am having some difficulties with some of the functionality of GDCM that worked without flaw on Linux, but will not compile on Mac.

 I tested the most basic code that will replicate the problem that I have ( Undefined symbols for architecture x86_64), and it seems that the code at http://gdcm.sourceforge.net/html/SortImage_8cxx-example.html is an example of some code which throws up this error. Incidentally, it is the gdcm::sorter type stuff that I am using in my project which causes this problem, hence why I chose this example.

  I thought that it had something to do with the libraries not linking correctly upon compilations, but there are other GDCM examples which do compile, suggesting that everything is defined ok.


The full output of the compilation failure is:-

Undefined symbols for architecture x86_64:

If someone could offer advice on this error, it would be very much appreciated.
