gcc of SDE6 cannot compile C++ applications

["colin" <colin@xxxxxxxxxxxxxx>]

Hi there,
I upgrade my SDE from 5 to 6.
Before upgrading, we can compile C++ applications. After doing that, C++
cannot be compiled by the gcc of SDE6.
The warning message is like this:
    mipsel-linux-gcc: main.cpp: C++ compiler not installed on this system

I found that MIPS offers C++ compiler running on MIPS.
Does MIPS want us to compile C++ on MIPS, not on X86?

Regards,
Colin
