Linking error on Mac OS X

Hi,
On Mac OS 10.2, using CodeWarrior 8.3, I was using UnicodeString class.
While using the three of the functions (which includes  a constructor), I
was getting the following link error.

Link Error   : undefined: 'icu_2_6::UnicodeString::doCaseCompare(long, long,
const wchar_t*, long, long, unsigned long)const ' (code) Referenced from
'icu_2_6::UnicodeString::doCaseCompare(long, long, icu_2_6::UnicodeString&,
long, long, unsigned long)const ' in HelloWorld.cpp

Link Error   : undefined: 'icu_2_6::UnicodeString::UnicodeString(const
char*, const char)' (code) Referenced from 'main' in HelloWorld.cpp

Link Error   : undefined: 'icu_2_6::UnicodeString::extract(int, int, char*,
unsigned long, const char*)const ' (code)
Referenced from 'main' in HelloWorld.cpp 

Just to give a back ground, I build ICU using gcc compiler and using the
dynamic libs in a CW project.
I have changed to umachine.h with the following to use plaform.h (this is to
avoid redefinition of int32_t)

#if defined(WIN32) || defined(_WIN32) || defined(WIN64) || 
defined(_WIN64)
#   include "unicode/pwin32.h"
#elif defined(__OS400__)
#   include "unicode/pos400.h"
#elif defined(__MWERKS__) && !defined(__MACH__)		//!defined(__MACH__)
added
#   include "unicode/pmacos.h"
#else
#   include "unicode/platform.h"
#endif

I suspect that the typedefs are not getting properly.  Or some thing is
going wrong.
In my program I have different typedefs to int32(signed long), uchar
(unsigned char), uchar16 (unsigned short), uint32(unsigned long).
The same code is working fine on Windows.
Please suggest.
thanks,
Venkat

I agree, there should be another way to detect Classic.

yes.,   if you like, could you file it on  
http://www.jtcsv.com/cgibin/icu-bugs please ? if not, I can file it.

could you try changing it to:

	#elif defined(__MWERKS__) && !defined(__MACH__)

and see if that works.
