Not sure why the switch would have done this, but:

exception doesn't exist in the top-level namespace. std::exception
should work.

I think some implementations of the STL (e.g. the Dinkumware STL that
came with MSVC++6; don't know if Dinkum-for-Linux does) define exception
in the top level namespace and then imports it into std with using
::exception. In other words, you can get away with either exception or
std::exception. Skimming the C++ standard quickly, you should probably
only rely on std::exception.

In general, 'Parse Error' really means 'undefined type'.

Hope that helps,
Rup.

Hi! 

I'm currently trying to compile a program that worked fine when I compiled
it on a g++ on SuSE 7.3. Then I switched to  g++ (GCC) 3.2 20020903 on
RedHat 8.0. 

This is what i get now: 
make -k 
g++ -ggdb -I../../include -c cexception.cc 
In file included from cexception.cc:17: 
cexception.h:31: parse error before `{' token 
cexception.h:36: destructors must be member functions 
cexception.h:36: virtual outside class declaration 
cexception.h:37: virtual outside class declaration 
cexception.h:38: virtual outside class declaration 
cexception.h:38: non-member function `int GetErrorMessageBufferSize()'
cannot 
   have `const' method qualifier 
.... 

from the headerfile cexception.h:

  virtual ~CException (); 
  virtual void SetErrorMessage (va_list args);

  CString m_sErrMsg; 
  int m_iErrNr; 
  PErrMsgList m_pErrMsg; 
};

#endif 

What is going wrong??? 

Please advise, 
Reinhard.
