Build mips-elf-gcc4.4.1 cross compiler for MIPS

Because ECOs needs MIPS-elf-GCC to compile the kernel, the GCC compiler of the latest gcc4.4.1 version is compiled today. The steps are as follows:

 

First, you must export the following variables before compiling:

Export target = MIPS-elf

Export prefix =/usr/local/$ Target

Export Path = $ path: $ prefix/bin

Echo $ Target

Echo $ prefix

Echo $ path

==============================

Compiling environment: fc9

The GCC version is as follows:

Use built-in specs.

Goals: i386-redhat-linux

Configuration :.. /configure -- prefix =/usr -- Mandir =/usr/share/man -- infodir =/usr/share/info -- With-bugurl = http://bugzilla.redhat.com/bugzilla -- enable-Bootstrap -- enable-shared -- enable-threads = POSIX -- enable-checking = release -- With-system-zlib -- enable-_ cxa_atexit -- disable-libunwind-exceptions -- enable-versions ages = C, c ++, objc, obj-C ++, Java, Fortran, ADA -- enable-Java-AWT = GTK -- disable-DSSI -- enable-plugin -- With-Java-home =/usr/lib/JVM/java-1.5.0-gcj-1.5.0.0/JRE -- enable-libgcj-Multifile -- enable-Java-maintainer-mode -- With-ECJ-jar =/usr/share/Java/eclipse-ecj.jar -- disable-libjava-multilib -- With-CPU = generic -- Build = i386-redhat-linux

Thread model: POSIX

GCC version 4.3.0 20080428 (Red Hat 4.3.0-8) (GCC)

======================================

Install binutils-2.19.1,

# Tar xjfv binutils-2.19.1.tar.bz2

# Mkdir build-binutils

# Cd build-binutils

# ../Binutils-2.19.1/configure -- target = $ target -- prefix = $ prefix

# Make all

# Make install

======================================

Install libgmp:

Note:

This library is used for high-precision operations.

If your system has a GMP library above 4.1, you do not need to install it.

 

Library used for computing:

Gmp-4.3.1,

# Mkdir build-GMP

# Cd build-GMP

# ../Gmp-4.3.1/configure -- prefix =/usr -- enable-shared

========================================================== ===

Install libmp FR,

Note:

This library is used for high-precision operations.

If your system's mpfr library is above 2.3.2, you do not need to install it.

 

 

# Mkdir build-mpfr

# Cd build-mpfr

# ../Mpfr-2.4.1/configure -- prefix =/usr -- enable-shared -- disable-static

========================================================== ===

Install GCC:

# Tar jxvf gcc-4.4.1.tar.bz2

# Mkdir build-gcc

# Cd build-gcc

# ../Gcc-4.4.1/configure -- target = $ target -- prefix = $ prefix -- without-headers -- With-newlib -- With-GNU-as -- With-GNU-LD

# Make all-GCC (Note: Here is make all-GCC)

# Make install-GCC (Note: Here is make install-GCC)

 

Note:

If you use the make install command for installation, the following error may be prompted (you won't use make install-GCC ):

Make [2]: Entering directory '/home/gcc-4.4.1/build-gcc/MIPS-elf/libstdc ++-V3'

Make [2]: *** the target "Install" can be created without rules ". Stop.

Make [2]: Leaving directory '/home/gcc-4.4.1/build-gcc/MIPS-elf/libstdc ++-V3'

Make [1]: *** [install-target-libstdc ++-V3] Error 2

Make [1]: Leaving directory '/home/gcc-4.4.1/build-GCC'

Make: *** [install] Error 2

 

Ignore it for the moment.

==============================================

Compile newlib-1.17.0,

# Tar jxvf newlib-1.17.0.tar.bz2

# Mkdir build-newlib

# Cd build-newlib

# ../Newlib-1.17.0/configure -- target = $ target -- prefix = $ prefix

# Make all

# Make install

========================================================

Recompile GCC,

Gcc-4.4.1

 

# Cd build-gcc

#.. /Gcc-4.4.1/configure -- target = $ target -- prefix = $ prefix -- With-newlib -- With-GNU-as -- With-GNU-LD -- disable-shared -- disable-libssp

# Make all (unlike the previous compilation, here is make all)

# Make install

 

With the support of newlib compiled just now, there will be no more errors.

==========================================

Install gdb-6.8

# Tar zxvf gdb-6.8.tar.gz

# Mkdir build-GDB

# Cd build-GDB

# ../Gdb-6.8/configure -- target = $ target -- prefix = $ prefix -- enable-sim-stdio

# Make all

# Make install

 

Done!

**************************************** *****

MIPs-elf-GCC is used to develop MIPS hardware programs. It cannot use dynamic libraries. Another interesting tool is MIPS-elf-run.

It is a MIPS simulator (simulator) in a PC. It can simulate and run the MIPs ELF Program.

 

The test is as follows:

mips-elf-gcc -Tidt.ld -mips4 -EL hello.c -o hello

mips-elf-run hello

The printed information is displayed.

 

The compile option-T specifies a default entry for the program. Otherwise, a warning is reported.

-El is used to generate an LSB program, that is, the small-end mode.
