c++_calls_f90_test


c++_calls_f90_test, C++ programs which illustrates how a C++ main program can call a FORTRAN90 subroutine.

For this example, the KRONROD package is used. Note that the KRONROD library is available in C++ and in FORTRAN90, so this example is not created out of necessity (the C++ main program could have simply called the C++ version of KRONROD). Instead, it is intended as an example of how to do this when you have to (you don't have a C++ version of the routines you want to use.)

When calling a FORTRAN90 routine from a C++ function, there are some simple things that may be enough to guarantee success.

Source Code:

kronrod_test is the C++ source code for the main program. Some changes have been made from the standard version in order to adjust for the fact that we are calling a FORTRAN77 subroutine.
