README for daqman

Installation on RHEL7

On a clean RHEL7 install, need to install the following package to include:

• imake
• boost-devel
• root
• root-spectrum
• zlib-devel

Notes on compiling, running, etc with the daqman system:

General info on daqman can be found on the github pages: http://bloer.github.io/daqman In particular, there is some doxygen code documentation at http://bloer.github.io/daqman/doc/html

Adding a ROOT class for saving:

Two steps are necessary to generate a new dictionary to store a class in a ROOT file or tree. First, in the class header file, you must call the macro

ClassDef(CLASSNAME,VERSION)

So the definition would look something like

class MyClass{
public:
  MyClass();
  ~MyClass();
  //blah blah functions
  ClassDef(MyClass,1)
};

Second, you must add your class to the LinkDef.h file in the top level directory. You must also add any template definitions, such as vectors of your class, if any are to be used. The link commands must be in the order that they are used, lowest level first. e.g., if you have a class Container which contains a vector<MyClass> from above, you would add the following lines to LinkDef.h:

#ifdef __CINT__
#pragma link C++ class MyClass+;
#pragma link C++ class std::vector<MyClass>+;
#pragma link C++ class Container+;
#endif

Notice the trailing + at the end of every link command. If you try to link Container before vector, it will not work.
