Hi, Greg.
I just read again you mail, more carefully.
You said that you used gdcm1.2.2 and your own programs linked corectly;
You downloaded gdcm1.3.2, and you get link errors on your programs, right?
In gdcm1.2, we made some stupid things, and we had to break the API, on
gdcm1.3 ...
On :
http://www.creatis.univ-lyon1.fr/Public/Gdcm
--> News
you can find :
* Stupid difference between gdcm::ValEntry and gdcm::BinEntry removed.
Only gdcm::DataEntry exist, now. Should have been considered as a
'Bug Fix'.
Actually, it's an API breaking modification ...
o std::string const &DataEntry::GetString() const
returns as a string (when possible) the value of the DataEntry
o void DataEntry::SetString(std::string const &value)
Sets the 'value' of a DataEntry, passed as a std::string
o void DataEntry::SetBinArea( uint8_t *area, bool self )
Sets the value (non string) of the current Dicom DataEntry
o void DataEntry::CopyBinArea( uint8_t *area, uint32_t length )
Inserts the value (non string) into the current DataEntry
o void DataEntry::SetValue(const uint32_t &id, const double &val)
Inserts the elementary (non string) value into the current
(multivaluated) DataEntry, at the id> position.
o double DataEntry::GetValue(const uint32_t &id) const
returns, as a double one of the values (when entry is
multivaluated), identified by its index id.
* DocEntrySet::GetEntryValue() replaced by DocEntrySet::GetEntryString()
API breaking modifications (since previous version)
* Stupid difference between gdcm::ValEntry and gdcm::BinEntry removed.
Only gdcm::DataEntry exist, now.
ValEntry(DictEntry *e);
BinEntry(DictEntry *e);
-->DataEntry *New(uint16_t group,uint16_t elem, VRKey const &vr);
std::string const &ValEntry::GetValue() const;
std::string const &BinEntry::GetValue() const;
-->std::string const &DataEntry::GetString() const;
uint8_t *BinEntry::GetBinArea();
-->uint8_t *DataEntry::GetBinArea();
void ValEntry::SetValue(std::string const &value);
void BinEntry::SetValue(std::string const &value);
-->void DataEntry::SetString(std::string const &value);
void BinEntry::SetBinArea( uint8_t *area, bool self = true );
-->void DataEntry::SetBinArea( uint8_t *area, bool self = true );
void ValEntry::CopyValEntry(uint16_t gr, uint16_t el);
-->void DataEntry::CopyDataEntry(uint16_t gr, uint16_t el, VRKey const &vr);
Example :
old way :
DocEntry *p3 = item2->GetDocEntry(0x0018,0x0050);
if( !p3 ) return false;
ContentEntry *entry2 = dynamic_cast(p3);
std::string thickness = entry2->GetValue();
new way :
DocEntry *p3 = item2->GetDocEntry(0x0018,0x0050);
if( !p3 ) return false;
DataEntry *entry2 = dynamic_cast(p3);
std::string thickness = entry2->GetString();
* Avoid too many source file modifications from gdcm1.2 to gdcm1.3
use :
#define ValEntry DataEntry
#define BinEntry DataEntry
#define GetEntryValue(g,e) GetEntryString(g,e)
#define GetEntryForcedAsciiValue(g,e) GetEntryString(g,e)
#define GetValEntry(g,e) GetDataEntry(g,e)
#define GetBinEntry(g,e) GetDataEntry(g,e)
#define GetValue() GetString()
#define InsertValEntry(v,g,e,vr) InsertEntryString(v,g,e,vr) // warning mind the VR!
#define InsertBinEntry(b,l,g,e,vr) InsertEntryBinArea(b,l,g,e,vr)
#define SetValEntry(c,g,e) SetEntryString(c,g,e) | !!
#define SetValEntry(c,en) SetEntryString(c,en) | !!
#define SetBinEntry(c,l,en) SetEntryBinArea(c,l,en) | !!
#define SetBinEntry(c,l,g,e) SetEntryBinArea(c,l,g,e) | !!
#define NewValEntry(g,e,vr) NewDataEntry(g,e,vr)
#define NewBinEntry(g,e,vr) NewDataEntry(g,e,vr)
Maybe this is the cause of your problems?
(Mathieu compiles, links and runs without any problem on VC2005)
