PyImport_Import Module("cString IO") failure with undefinedsymbol

[Borse, Ganesh]

Hi,
Can you please guide me for the following problem?
The call to "PyImport_Impor tModule("cStrin gIO");" is failing with an error of "undefined symbol: PyObject_SelfIt er".

Before importing this module, I am importing only the sys module.

Py_SetProgramNa me("/usr/bin/python");
Py_Initialize() ;
char* argv[] = { "python","-v",""};
PySys_SetArgv(2 ,argv);
PyRun_SimpleStr ing("import sys");

PyObject *modStringIO = NULL;
// Import cStringIO module
modStringIO = PyImport_Import Module("cString IO");

Should I be importing any other additional module(s) to make this import work?

Please help.

I am trying to use the function GetPythonErrorM essage provided in this post:

Thanks in advance for your help.
Regards.

Function "PyObject_SelfI ter" is part of libPython.a. But when library
which is linked with libPython.a tries to import cStringIO (which is
nothing but dlopen("lib-dynload/cStringIO.so"), ld.so does not find
this symbol.
So, as a workaround, we can get the cStringIO.so also linked with the
library which has linked libPython.a.
By this we ensure that PyObject_SelfIt er is already resolved in the
library.
Then at the time of importing cStringIO at runtime, this symbol is
already referenced & won't cause problems.
