Help!! libstdc++-v3 build for cross compiler target powerpc

[Xiaopeng Gong]

Hello,
      Help!!!

      The cross compiler build failed to build libstdc++ for powerpc .  Any
help will be greatly appreciated!


	I am trying to build the cross compiler GCC on Red Hat 6.2 target to
powerpc embeded system.

	The source I have downloaded are:
	binutils 2.10.1
	GCC-core 2.95.2
	GCC-g++  2.95.2

	I have successfully build and installed the C compiler and tested the Hello
World program, however, the C++ compiler was built, but the libstdc++ was
unsuccessful, thus I got a C++ compiler can generate object code, but the
link needs to link to the library -- which failed to build.

	I have tried in the GCC directory just build the library ..
	ie:  in the GCC source directory
		GCC/gcc-2.95.2/libstdc++
		GCC/gcc-2.95.2/mklibstdc++

		cd GCC/gcc-2.95.2/mklibstdc++,


../configure --target=powwerpc-unknown-eabi --prefix=/tools --with-gnu-as --
with-gnu-ld
		make

	Now it gives me the error of

	I have also downloaded the libstdc++ package and just try to make the
library, however I got about the same problem as
