How to compile a fortran code with a C++ subroutine in Linux system?

[mynumber]

Hi, all!

I am encountering a problem. I write a C++ code and want to connect it witha fortran code,but I do not know how to compile the fortran program with a C++ subroutine.Do you have any ideas? Thanks!

As you don't give any specifics, you should be able to get many relevant ideas by looking things up. Your search should include the documentation of your Fortran compiler. In general, if you want it to work with many brands of Fortran, you would use "extern C" to make the interface C-compatible on the C++ side. Then, you could use any C interface example you find to get it working, before tinkering with sugar such as C++ parameters by reference.

Thanks for your reply!Unfortunately, I am aprimary learner, and I still do not how to deal with it.

Now I describe my situation in detail.I use the Fortran program so as to generate some kinetics data, and then make data processing by the C++ code. Since thedata at each time step need beprocessed, I want to call the C++ code as a subroutine of the Fortran program.But I do not know how to compile the two files and form a single executable file. BTY,the compilersin the LinuxOSareifc and g++.

Could you tell me detailedly?

Make a .o for the C++ code, and include it in the Fortran build. Depending how much C++ you use, you may require C++ library specifications:

icpc -c yourcxx.cpp
ifort yourfort.f yourcxx.o -lstdc++ -lunwind
