Dear Fons and Valery,
Good Day...
How do we deal with the LinkDef.h file in a compile code?
Do we need to write it as a header-include-line
(i.e., #include "testLinkDef.h") in the class prototype/declaration?
In the manual, creation of this file is explained. But I would like to
know how this file relates to the main file or Dictonary file or the class
declaration file. Is it automatically detected during compilation?
My intention is to create a global variable like gROOT. Then I will use
this variable for the TButton functionality.
>From this file,
http://root.cern.ch/root/roottalk/roottalk98/0277.html
I created a test code and appended them here.
I used the command line:
g++ -o myexe test.cc testDict.cc `root-config --cflags --glibs`
But error mesg is: gSB undeclared
What is wrong with this test code, and how do we correct it?
Sorry for being slow here...
I would appreciate very much your reply.
Thank you.
