Establishment of MIPS-ELF-GCC cross-compilation environment

/**************************************************************************************

Mips-elf's cross compilation environment originates from an article in the network, but I can't find the source. At the same time, after my

Some modifications, and finally I successfully configured this cross compilation environment in Slackware 12.0 Linux. As for

Other versions of Linux I believe should be able to compile successfully, but I will be in other Linux as soon as possible

Verified, so as to facilitate everyone's reference. Please correct me for the deficiencies.

**************************************************************************************/

The following is steps to build cross compilers. So far, I tried a for PowerPC and MIPS.

Basically, all your have to do are to follow the following 9 steps. Download sources Set Environment variables build binutils builds bootstrap gcc build newlib builds gcc again with newlib GDB With PSIM Compile your code Run 1. What do you need?

Have to obtain the following source codes binutils Http://www.gnu.org/software/binutils/GCC http://www.gnu.org /software/gcc/gcc.html newlib Http://sources.redhat.com/newlib/GDB http://www.gnu.org/software/gdb/gdb.html 2. Set Environment Variables

Choose your taget such as Powerpc-eabi, Powerpc-elf, mips-elf, and so on

For bash simply type

% Export Target=powerpc-eabi

% Export prefix=/usr/local/$TARGET

% Export path= $PATH: $PREFIX/bin

3. Build Binutils

% tar xjfv binutils-2.17.tar.bz2

% mkdir build-binutils

% CD Build-binutils

% .. /binutils-2.17/configure--target= $TARGET--prefix= $PREFIX

% make all

% make Install

4. Build Bootstrap GCC

% tar xjfv gcc-4.1.1.tar.bz2

% mkdir BUILD-GCC

% CD BUILD-GCC

% .. /gcc-4.1.1/configure--target= $TARGET--prefix= $PREFIX--without-headers--with-newlib  --with-gnu-as-- With-gnu-ld

% make ALL-GCC

% make INSTALL-GCC

--with-gnu-as--with-gnu-ld prevents native assembler on certain architectures. (For others, this does not have any effects) 5. Build Newlib

Newlib provides standard C library for embedded systems

% mkdir Build-newlib

% CD Build-newlib

% .. /newlib-1.14.0/configure--target= $TARGET--prefix= $PREFIX

% make all

% make Install

6. Build GCC again with Newlib

% CD BUILD-GCC

% .. /gcc-4.1.1/configure--target= $TARGET--prefix= $PREFIX--with-newlib--with-gnu-as--with-gnu-ld--disable-shared- Disable-libssp

% make all

% make Install

7. GDB with PSIM

% tar xjfv gdb-6.3.tar.bz2  

% mkdir Build-gdb

% CD Build-gdb

% .. /gdb-6.3/configure--target= $TARGET--prefix= $PREFIX--enable-sim-powerpc

--enable-sim-stdio

% make all

% make Install

congratulations! Build your tool chain 8. Compile Your code

Now, the IT ' s time to compile your code.

% powerpc-eabi-gcc-mcpu=405 Hello.c-o Hello-msim

% MIPS-ELF-GCC-TIDT.LD-MIPS4 Hello.c-o Hello

-T option specifies libraries that include start code.

To Compile with specific Memory map

% powerpc-eabi-gcc-wl,-ttext,0x4000,-tdata,0xf000 Hello.c-msim

(-wl,-ttext,0x4000,-tdata,0x10000)

9. Run

% Powerpc-eabi-run Hello

% Mips-elf-run Hello
