C++ And Loaded Code And Static Lib

• SD C++ And Loaded Code And Static Lib Apr 16 2010, 21:25
  I have a static library that I've built.  This library consists of
  mostly C++ classes in a separate namespace (call it MyNameSpace).
  
  I also have two pref panes (think of them as Code bundles that get
  loaded into an app).  Both of these pref panes statically link with
  my library.
  
  However, when the second pref pane/code bundle is loaded, it uses the
  classes loaded from the first pref pane/code bundle (even if the
  classes have different implementations but the same names).
  
  How do I get each pref pane/code bundle to use the classes it linked
  with, rather than looking them up from previously loadded code?
  
  I knew this was a problem with Objective-C, but I had though C++
  didn't have this problem.
  
  Thank you muchly, this a huge problem for me.
  
  SD.

  Shouldn't two-level namespaces solve this problem?

  Wow, twisted stuff.
  
  One of my API extern C functions was using some functions that had
  the inline keyword on them.  When using inline, the wrong someFunx()
  gets called.  Remove the inline and it seems to work fine.
  
  What a waste of a day.
  
  -----------------------------------------------------------
  inline void someFunx()
  {
    someOtherFunx();
  }
  
  extern apiFunx()
  {
    //calls the wrong someFunx() if inline used on someFunx()
    someFunx();
  }
  -----------------------------------------------------------
  
  Thanx for the responses, hope this helps someone in the future (come
  get me Google).
