using all the correct libraries. But there is one thing you
cannot do
in MSC compiler:

#if defined(WIN32)
#if (defined(gdcmCommon_EXPORTS)
#define GDCM_EXPORT __declspec( dllexport )
#else
#define GDCM_EXPORT __declspec( dllimport )
#endif
#else
#define GDCM_EXPORT
#endif

class GDCM_EXPORT String : public std::string { ... }

Could someone please let a poor UNIX guy understand what is the
issue
here (I have very little knowledge on ho dll actually works) ?

You said that Toolkit 2003 does not support dynamic linking. If it
is so, then you cannot share standard containers between modules.
It happens because each module has its own instance of CRT, which
tracks allocations. Hope this helps:
