Compile Errors After Upgrading to GCC 3.0.2 from GCC 2.95.2

Compile Errors After Upgrading to GCC 3.0.2 from GCC 2.95.2

[dannyngo]

Hi,

I have a source file that compiles successfully with g++ 2.95.2 but not
with
g++ 3.0.2.  I'm running it on SuSE Linux 7.1.  Here's an example of the
kind
of errors I'm getting:

g++ -w -Wall -I. -c ggRasterSurfaceTexture.C
ggRasterSurfaceTexture.C: In constructor
   `ggRasterSurfaceTexture::ggRasterSurfaceTexture(std::istream&)':
ggRasterSurfaceTexture.C:58: no matching function for call to
   `std::basic_istream<char, std::char_traits<char> >::get(unsigned char&)'

/usr/local/include/g++-v3/bits/istream.tcc:471: candidates are: typename
   _Traits::int_type std::basic_istream<_CharT, _Traits>::get() [with
_CharT
=
   char, _Traits = std::char_traits<char>]
/usr/local/include/g++-v3/bits/istream.tcc:503:
   std::basic_istream<_CharT, _Traits>& std::basic_istream<_CharT,
   _Traits>::get(_CharT&) [with _CharT = char, _Traits =
   std::char_traits<char>]
/usr/local/include/g++-v3/bits/istream.tcc:537:
   std::basic_istream<_CharT, _Traits>& std::basic_istream<_CharT,
   _Traits>::get(_CharT*, int, _CharT) [with _CharT = char, _Traits =
   std::char_traits<char>]
/usr/local/include/g++-v3/bits/std_istream.h:157:
   std::basic_istream<_CharT, _Traits>& std::basic_istream<_CharT,
   _Traits>::get(_CharT*, int) [with _CharT = char, _Traits =
   std::char_traits<char>]
/usr/local/include/g++-v3/bits/istream.tcc:583:
   std::basic_istream<_CharT, _Traits>& std::basic_istream<_CharT,
   _Traits>::get(std::basic_streambuf<_CharT, _Traits>&, _CharT) [with
_CharT =
   char, _Traits = std::char_traits<char>]
/usr/local/include/g++-v3/bits/std_istream.h:164:
   std::basic_istream<_CharT, _Traits>& std::basic_istream<_CharT,
   _Traits>::get(std::basic_streambuf<_CharT, _Traits>&) [with _CharT =
char,
   _Traits = std::char_traits<char>]

Any ideas on the cause of such errors?  Thanks for any help!

You can't get a 'unsigned char' out of a 'char' stream directly.

GCC already told you what kind of `get' functions the
std::basic_istream class provides, just select the appropriate one.
