Re: [Tutor] [tutor] Calling python from a c program

[Varsha Purohit]

I am gettng following linking errors

  [Linker error] undefined reference to `_imp__Py_Initialize'
  [Linker error] undefined reference to `PyRun_SampleString'
  [Linker error] undefined reference to `_imp__Py_Finalize'

I think i need to set the path to the linker... may be i need to pass
linking options of python to the c compiler... but wat are those options :(
??

Where did you read it? There are several sources of info 
on embedding Python in C, some better than others.

You don't call the python interpreter screen
(ie the >>> prompt) from C you call the interpreter itself.
The interactive interpreter is a C program in its own right.

You could write your own fairly easily or you could use 
the PyShell GUI component that is part of the wxPython 
package.

But usually you just want to interpret some Python 
commands much as you did in your example.

HTH,

It might help to tell us
- what platform you are using
- what compiler
- what link errors

[Tutor] [tutor] Calling python from a c program

[Varsha Purohit]

Hi,
   I just read about how to call python from a c program. This is the
function for that

int main()
{
 Py_Initialize();
PyRun_SampleString("print 76");
Py_Finalize();

return 0;
}


But i am getting an error of header file. python.h not found. Can anybody
tell me where can i get this header file ?? And how can i call the python
interpreter screen from c program ??
