[Clas_offline] C++ fnc call from Fortran

[Taisiya Mineeva]

Hello,

I am writing to you with the question concerning calling a C++/ROOT
function in Fortran code.

I have a working test example of an external C++ function that is called
in Fortran. This compiles/links well with g77/g++. However, the same
procedure for compiling and linking does not work with gfortran/g++.

My problem is that in order to compile Lepto generator (Fortran), where I
am calling a C++ fnc, I need to use a set of cernlibs that have been
compiled with gfortran.  But the call in Fortran to C++ function does not
compiles with gfortran.

I would appreciate some guidance as to how proceed with gfortran/g++ on
JLab CUE to call C++ from Fortran.

Thank you in advance,
Taya
