Error when compiling libgcc

I'm getting this error:

Google says that error means your cross-binutils is not installed correctly. And looking at your script, I see one possible reason why.

Code: Select all

			--target=$DIR/$COMPILER_TARGET \

There should be no directories in your target triplet.

Now I get this error

Google says that error means you're trying to build GCC in the same directory where you unpacked the GCC source. You need to run the configure script in a separate directory.
