Rtems development environment Construction--based on FreeBSD system

December 08, 2015 Tuesday

This article is a record of the installation of the RTEMS-4.10.2 development environment, and is only a record, not the process of doing too much research on the principle.

1, the use of the FreeBSD 9.3 version of the system, the system comes with the gcc-4.2.1 compiler, and it will complete the environment in the construction of the various programs compiled work;

2, this article uses RTEMS-4.10.2 edition source code;

3, the following describes the installation process of the development environment:

(1) Install bash

FreeBSD defaults to the/BIN/CSH and/bin/sh two shell, but in my testing process, I found neither of these shells can successfully compile Rtems source code, but in the use of bash can be successful.

Therefore, you need to install bash first, which can be installed by port:

Cd/usr/port/shell/bash

Make install

Use the CHSH command to change the user's default shell to bash, where you can refer to the relevant FreeBSD manuals;

(2) Install GNU make

Since FreeBSD 9.3 uses Berkeley make as the default, and the programs we want to compile are all managed by GNU made, we need to install GNU makes;

Download the make-3.82.tar.bz2 source code from the ftp://ftp.gnu.org website and install the following:

TAR-XJF make-3.82.tar.bz2

mkdir Build_make

CD Build_make

.. /make-3.82/configure

Make

Make install

When the installation is complete, both make and gmake are present in the system, and gmake management is used by default.

(3) Installation Texinfo

Download the texinfo-4.9.tar.gz source code from the ftp://ftp.gnu.org website and install the following:

Tar-xzf texinfo-4.9.tar.gz

mkdir Build_texinfo

CD Build_texinfo

.. /texinfo-4.9/configure

Gmake

Gmake Install

(4) Installation of GMP, MPFR, MPC Library

Download gmp-5.0.4.tar.bz2, mpfr-2.4.2.tar.bz2, mpc-1.0.3.tar.gz source from ftp://ftp.gnu.org website, install in the following order:

A. Install gmp-5.0.4:

TAR-XJF gmp-5.0.4.tar.bz2

mkdir Build_gmp

CD BUILD_GMP

.. /gmp-5.0.4/configure--prefix=/usr/local/gmp (prefix for specifying the installation directory)

Gmake

Gmake Install

B. Install mpfr-2.4.2:

TAR-XJF mpfr-2.4.2.tar.bz2

mkdir BUILD_MPFR

CD BUILD_MPFR

.. /mpfr-2.4.2/configure--PREFIX=/USR/LOCAL/MPFR--with-gmp=/usr/local/gmp (reference GMP)

Gmake

Gmake Install

C. Install mpc-1.0.3:

Tar-xzf mpc-1.0.3.tar.gz

mkdir BUILD_MPC

CD BUILD_MPC

.. /mpc-1.0.3/configure--PREFIX=/USR/LOCAL/MPC--with-gmp=/usr/local/gmp--WITH-MPFR=/USR/LOCAL/MPFR (reference GMP,MPFR)

Gmake

Gmake Install

D. Adding environment variables

At the end of/etc/profile, add the following:

Export Ld_library_path=/usr/local/gmp/lib:/usr/local/mpfr/lib:/usr/local/mpc/lib: $LD _library_path

Source/etc/profile (update environment variables)

(5) Installation of binutils, GCC

Download the following source code from ftp://ftp.rtems.com/pub/rtems/SOURCES/4.10/official website:

binutils-2.20.1.tar.bz2

Binutils-2.20.1-rtems4.10-20140214.diff

Newlib-1.18.0.tar.gz

Newlib-1.18.0-rtems4.10-20130320.diff

gcc-4.4.7.tar.bz2

Gcc-4.4.7-rtems4.10-20130320.diff

A. Install Binutils:

TAR-XJF binutils-2.20.1.tar.bz2

CD binutils-2.20.1

Cat.. /binutils-2.20.1-rtems4.10-20140214.diff | Patch-p1

Cd..

mkdir build_binutils

CD Build_binutils

.. /binutils-2.20.1/configure--target=arm-rtems4.10--prefix=/opt/rtems-4.10--disable-werror

Gmake

Gmake install (requires root access)

Insert a row at the end of ~/.profile:

Export Path=/opt/rtems-4.10/bin:${path}

To execute the command again:

SOURCE ~/.profile (Update environment variable)

B. Installing GCC:

TAR-XJF gcc-4.4.7.tar.bz2

CD gcc-4.4.7

Cat.. /gcc-4.4.7-rtems4.10-20130320.diff | Patch-p1

Cd..

Tar-xzf newlib-1.18.0.tar.gz

CD newlib-1.18.0

Cat.. /newlib-1.18.0-rtems4.10-20130302.diff | Patch-p1

Cd.. /gcc-4.4.7

Ln-s.  /newlib-1.18.0/newlib. (Create a soft link)

Cd..

mkdir BUILD_GCC

CD BUILD_GCC

.. /gcc-4.4.7/configure--target=arm-rtems4.10--with-gnu-as--with-gnu-ld--with-newlib--verbose--enable-threads-- Enable-languages= "c,c++"--prefix=/opt/rtems-4.10--with-gmp=/usr/local/gmp--WITH-MPFR=/USR/LOCAL/MPFR

Gmke All

Gmake Info

Gmake install (requires root access)

When all of the above compiles and installs successfully, the installation process for the compilation environment ends.

4. Verify that the environment is installed correctly

(1) from the Rtems official website ftp://ftp.rtems.com/pub/rtems/4.10.2/download rtems-4.10.2 source code;

(2) Compile the source code;

TAR-XJF rtems-4.10.2.tar.bz2

mkdir Build_rtems

CD Build_rtems

.. /rtems-4.10.2/configure--target=arm-rtems4.10--enable-posix--enable-networking--enable-cxx--enable-rtemsbsp= smdk2410--prefix=/opt/rtems-4.10/

Gmake All

SU Root (switch to root account)

Gmake Install (root privilege)

If there is no error, it indicates success.

At this point, the end!
