I am using root version 5.22/0 on Vista. I have a class that inherits from TObject. The .h file contains#if !defined(__CINT__) || defined(__MAKECINT__)
ClassDef(CScopeHeader,1)
#endif
and the .cpp file contains#if !defined(__CINT__) || defined(__MAKECINT__)
ClassImp(CScopeHeader)
#endif
I have written my own Streamer for the class. I can build a .DLL using this class with a linkdef.h file containing the line#pragma link C++ class CScopeHeader-;
and everything works just fine. However, if I try to use ACLiC[quote].L ScopeHeader.cpp+[/quote]I get the following error[quote]root [12] .L CScopeHeader.cpp+
Info in TWinNTSystem::ACLiC: creating shared library c:\Analysis01\CScopeHeader_cpp.dll

Error in : Compilation failed![/quote]Is there a way to work around this problem? Is there some way to let ACLiC know that there is already a Streamer()? Thanks
You need to make sure that ACLiC sees the line:#pragma link C++ class CScopeHeader-; which you can do by either putting it inside your header file or within a file named ScopeHeader_linkdef.h
Still unsing root 5.22/0 on Vista. Another problem that appears to be aclic related. I have a class that has members that are of type MATCHSTRUCT defined by a typedef that I would like to include within the class definition section of the .h file:private:
typedef struct{
char cat;
char nhits;
short x;
short y;
.
.
} MATCHSTRUCT
.
.
.
MATCHSTRUCT *fMatch;
When I try to compile from the commandline with.L CThreeHit.cpp+I get all these errors:[quote]Info in TWinNTSystem::ACLiC: creating shared library c:\Analysis01\CThreeHit_cpp.dll

Error in : Compilation failed![/quote]However, if I put the typedef OUTSIDE the class definition, it compiles and runs fine. However, since the struct is only used within the class, I would prefer to hide it there… I have tried including a CThreeHit_linkdef.h - makes not difference.
Finally,when I include the .h and .cpp as part of a Visual Studio 2008 .DLL project, it compiles and runs just fine regardless of where the typedefs are located (inside the class definition or outside)
? Can you try:
