Hi again
 Thanks for the info.  The CPLUS_INCLUDE_PATH thing worked.

I've developed a simple little test program, and I seem to be having all
sorts of problems.

File Test.h
.......................
#ifndef TEST_H_INCLUDE
#define TEST_H_INCLUDE


class CTest
{
protected:
 int m_n ;
public:
 CTest( int ) ;
 virtual void print( ) ;
};

#endif //TEST_H_INCLUDE
............................

File main.cpp
.............................

#include ...{{ the relevant headers }}

CTest::CTest( int n )
{
 m_n = n ;
}

void
CTest::print( )
{
 printf("goodbye sanity" ) ;
}

.............................

and I now get this
.............................

/psx2/bin/ld.exe: warning: global constructor
_GLOBAL_$I$__always_have_this_glob
al used
main.o: In function `CTest type_info function':
test.h(.text+0xd4): undefined reference to `__rtti_user'
test.h(.text+0xd4): relocation truncated to fit: JMPADDR __rtti_user
NMAKE : fatal error U1077: '\psx2\bin\ld.exe' : return code '0x1'
Stop.
............................

When I take out the 'virtual' from the 'print' declaration, it works fine,
although the output file 'demo' is almost 20k !


P.S.  I've done a 'bit' of research (in the gcc .txt file), and can find no
mention of this problem.


Yours going berzerk
