Is there any method to call C++ class

[weichao]

I have some codes were written by C++. There are many CLASS definition. Is there any method could use variables and fumctions of C++ CLASS. Or I have to modify C++ code to C.

You cannot call C++ class members directly, at not easily. You don't have to rewrite the C++ code, but you can write either C-style wrappers or C++ static class member functions around C++ class methods. These are callable from Fortran as they don't expect this as the first hidden argument. You have to find the means to pass this (i.e. pointer to class object) around -- usually, you pass this from C++ to Fortran as an INTEGER, and pass it back to above-mentioned wrapper unmodified.

See this thread for a sample.
