Static Build Possible?

[Anonymous]

Thanks for this great library.
I was wondering if it is possible to perform a static build of pythonqt lib? If so, what parameters do I need to change in the build process?
Thanks

Never tried, you probably just use the "staticlib" instead of the "dll" keyword in the CONFIG line of PythonQt.

So I was able to successfully compile static PythonQt lib. But I get these errors when using the lib to compile examples…

From my limited understanding of dynamic libs… it seems that the compiler expects the functions and objects to be dll linked in the lib rather than static, since the classes and methods were defined as such.

Is there a way around that? What I hoped to achieve was a single static PythonQt.lib (or PythonQt_All.lib) such that my exe would only require the python26.dll upon execution.

Thanks

You need to patch PythonQtSystem.h
and always define PYTHONQT_EXPORT as empty:

#define PYTHONQT_EXPORT

otherwise the VC compiler will expect that the symbols are in an external DLL.

I compiled replacing code in PythonQtSystem.h

#ifndef _PYTHONQTSYSTEM_
#define _PYTHONQTSYSTEM_
/*
 * Copyright (C) 2010....
    .....
 */
#ifdef WIN32
  #ifdef PYTHONQT_EXPORTS
    #ifdef PYTHONQT_STATIC_LIB
      #define PYTHONQT_EXPORT
    #else
      #define PYTHONQT_EXPORT __declspec(dllexport)
    #endif
  #else
    #ifdef PYTHONQT_STATIC_LIB
      #define PYTHONQT_EXPORT
    #else
      #define PYTHONQT_EXPORT __declspec(dllimport)
    #endif
  #endif
#else
  #define PYTHONQT_EXPORT
#endif

And define PYTHONQT_STATIC_LIB in PythonQt library and application
