从fortran调用C ++函数而不是C [英] calling C++ function from fortran not C

问题描述

是否可以从FORTRAN调用一个C ++函数，比如

  #include< iostream.h> 
 externC
 {
 void single_cell（void）
 {
 cout<<Hi from C ++; 
 
 
 
 
 
 
 $ b 
所以当我使用C时，它工作正常，但使用C ++函数时，它会给出错误，例如
对cout等的未定义错误。
解决方案
 
 g ++和gfortran都用作链接器，带来额外的图书馆。这就是为什么Fortran / C ++组合比Fortran / C组合更复杂的原因......只需使用正确的编译器作为链接器就行不通，您需要添加一个库。已经建议与gfortran链接并指定C ++运行时库。您还可以链接到g ++并指定Fortran运行时库。有关这两种方法的详细信息，请参阅使用gcc链接fortran和c ++二进制文件 。
 
is it possible to call a C++ function from FORTRAN such as 
#include <iostream.h>
extern "C"
{
    void single_cell(void)
    {
        cout<<"Hi from C++";
    }
}
So when I am using C it is working fine but with the C++ function it gives errors like 
Undefined error to cout  etc 
解决方案
Both g++ and gfortran, used as linkers, bring in extra libraries.  That is why the Fortran/C++ combination is trickier than the Fortran/C combination ... just using the correct compiler as the linker won't work, you need to add a libary.   Already suggested is to link with gfortran and specify the C++ runtime libraries.   You can also link with g++ and specify the Fortran runtime libraries.   See Linking fortran and c++ binaries using gcc for the details of both approaches.
