Actually according to the above operation, mainly installs the gcc-4.6.2 to appear some problems, originally installs under the Cygwin, the result hint lacks 3 things, compiles gcc to fail.
Under CentOS, yum-y install Mpfr-devel libmpc-devel gmp-devel
Later, I was prompted with an error, (I was installed under 64-bit CentOS), so I need to install glibc-devel.i686, and I may need to install libgcc.i686. Right
After the first installation fails, do not perform the install_gcc-4.6.2.sh again. CD Gcc-graph/objdir,sudo make
Result "/USR/BIN/LD:. Libs/alloc.o:relocation r_x86_64_32 against '. rodata.str1.8 ' can not is used when making a shared object ; Recompile with-fpic "Such errors still reported, it appears that Google needs to see how to install the steps."
