Hello:
I have a linbrary named as PWLib which has been suceessfully compiled using gcc. But when I using a cross compiler on arm7tdmi+uclinux, there are many warnings such as the following:
/home/stone/pwlib/include/ptlib/object.h: In function `class _STL:ostream
& operator <<(_STL:ostream &, const PFloat80l &)':
/home/stone/pwlib/include/ptlib/object.h:2604: ambiguous overload for
`_STL::basic_ostream<char,_STL::char_traits<char> > & << const long double &
/usr/local/arm-elf/stlport/stl/_ostream.h6: candidates are: class
_STL::basic_ostream<char,_STL::char_traits<char> > &
_STL::basic_ostream<char,_STL::char_traits<char> >:operator <<(unsigned
char)
/usr/local/arm-elf/stlport/stl/_ostream.h8: class
_STL::basic_ostream<char,_STL::char_traits<char> > &
_STL::basic_ostream<char,_STL::char_traits<char> >:operator <<(short int)
Someone told me that is becuase the gcc using libstdc++ while the cross compiler STLport C++. So would you please tell me what is the difference between libstdc++ and STLportC++. How can I change the pwlib codes so that it can cooperate with STLport C++.
Thank you very much in advanced.
Bestwishes
