Supports C ++ 0x GCC Installation

There are a lot of tutorials on the Internet, but there are still some problems according to the tutorials...

Some tutorials are misleading:In the configure of GCC, we found that the system does not have GMP and mpfr. On the official website of GNU, I got a GMP and an mpfr on the official website of mpfr.

In fact, it does not need to be so complicated. compile it as follows:

1. Get the latest GCC versionSVN checkout SVN: // gcc.gnu.org/svn/gcc/trunk somelocaldir
2. Obtain the compilation dependency:./Contrib/download_prerequisites
3. ./Configure -- prefix = $ home
4. Make & make install

After compilation, the latest GCC is installed in the $ home/bin folder. You can use g ++ in this folder to compile the C ++ 0x file, you only need to add the-STD = C ++ 0x compilation option.
