I followed this link
http://wiki.osdev.org/GCC_Cross-Compiler to create cross compiler , downloaded following files gcc-4.8.2 , mpc-1.0 , isl-0.14 , mpfr -3.1.2 and gmp 6.0.0a and extracted to folder gccx .It works fine for
Code: Select all
cd $HOME/src
mkdir build-binutils
cd build-binutils
../binutils-x.y.z/configure --target=$TARGET --prefix="$PREFIX" --with-sysroot --disable-nls --disable-werror
make
make install
When i run "make all-gcc" then it produces errors which can be found here
http://pastebin.com/cjfX43C8
I tried by downloading gcc-4.9.0 but it didn't work .
gcc and g++ are already installed version 4.8.2 , OS ubuntu 14.04 LTS.
How to resolve this error ?

You are not following the instructions. You are not giving us enough information to help you.
There is no "make gcc-all" command. You mean "make all-gcc". This means we cannot trust anything you say if it is wrong.
You need to:
- Go into the preferences of your terminal emulator and set scrollback to unlimited.
- Delete what you currently have. Build directories, extracted source code, delete it all.
- Close your terminal.
- Open a new terminal.
- Start over.
- Follow the instructions carefully.
- When things go wrong, stop.
- Copy everything in your terminal into a text file.
- Upload that text file in a pastebin.
- Post a link to the paste.
This way we can see *exactly* what you did. If you don't follow the instructions and tell us exactly what you did, then you won't succeed.
Don't be stupid. Replace gcc-x.y.z with gcc 4.9.1 if that is the version you used.

I had some similar trouble once. Adding the extra option to the configure command line fixed it for me
Code: Select all
../binutils-x.y.z/configure --target=$TARGET --prefix="$PREFIX" --with-sysroot --disable-nls --disable-werror CC=gcc-4.8.2

This setting didn't work for make all-gcc .

What are your exact configure and make command lines? (Copy/paste, no typos this time please.)

why --prefix="$PREFIX" and not --prefix=$PREFIX?

I just did the same on my Ubuntu 14.04.1 Ubuntu LTS notebook - for i786-elf, x86_64-elf, mips-elf... and m68k-elf is compiling right now. I expect it to work for arm-eabi, powerpc-elf and my other build targets as well.

Ok let forget about typo error . Check pastebin file , there is an error . This error doesn't occur due to copy/paste there is something behind the error .
