Tizen Developers

Hello - When I compile a Tizen 2.0.0a package I see this version of gcc in use within the scratch.i586.0 folder hierarchy : /path/to/GBS-ROOT-profile.tizen2.0a/local/scratch.i586.0/usr/bin/gcc --version gcc (GCC) 4.5.3 Copyright (C) 2010 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. Questions: 1 - Is this the only g++ compiler available in Tizen? 2 - It *appears* that this g++ compiler does not support the Intel SSSE3 ( http://en.wikipedia.org/wiki/SSSE3 ) instruction set. Is this true? 3 - Does the Tizen IVI profile use the same g++ compiler? Thank You, Carlos
