I am writing a program in Dev c++, and I am trying to include several ROOT libraries.

When my code attempts to compile and run I get error such as:


An example of some of the libraries I am trying to include:

TTree.h
TStyle.h... etc

they are located in E:\root\libraries and I have made sure to include that folder in the library section of the compiler options window under tools.

Any ideas suggestions on how to link or resolve this error?

Hi I'm new to this forum and computer programming in general, this is my first post (Just a warning of potentially offensive mistakes I might make)

Apparently the compiler found TStyle.h; otherwise it never would have reached the linker stage. The header contains the class definition, including function prototypes. It apparently does not contain the actual implementation of the class methods. (This is normal.)


Now, here's the question: Were you given a library file (probably named "something.a").? If you were, then note that this must have been compiled with system libraries consistent with your particular vintage compiler and libraries.

Or were you given source files (probably with names like "TStyle.cpp" or "Tstyle.cxx" and other .cpp or .cxx files)?

If TStyle is a derived class, then you will need source for the base class(es) also.

Bottom line: You will have to put the library or the source files in your project in order to use these classes in your application. If you weren't given source files, then you will have to get them from wherever you got the header files.
