Extern C- Callinf Fortran from C++

[jerome12345]

Thanks a lot,

Please find attached a file anmed calculator.zip.

It is actually generally through the wizard which of an external software which has all the class definitions.

As you see it has extern c defined.

NExt, I have also attached test.zip which ahs the fortran function in test.F

There is also a file test.cpp.

With the same linker and config settings, if I call the FORTRAN function from test.cpp it works.

But, when I call from calculator.cpp it doesn't.

I shall be grateful and obliged if helped as it is giving me sleeples nights for my task .

Thanks in advance
