告诉你Ubuntu 12.10搭建RTEMS开发环境的方法及命令

2015-06-05 18:08:08 来源:中存储网

1.首先下载工具包

2.使用tar zxvf或tar jxvf解压下载下来的工具包;

3.为各工具包打上补丁,接下来以binutils为例,gcc和newlib步骤相同:

cd binutils-2.20.1/
cat ../binutils-2.20.1-rtems4.10-20100826.diff | patch -p1

4.安装binutils:

cd ../
mkdir build-binutils
cd build-binutils
../binutils-2.20.1/configure --target=i386-rtems4.10 --prefix=/opt/rtems-4.10 --disable-werror
make
make install

若不添加部分选项,则会出现以下错误:

../../binutils-2.20.1/bfd/compress.c: 在函数‘bfd_uncompress_section_contents’中:
../../binutils-2.20.1/bfd/compress.c:54:45: 错误: 形参‘buffer’被设定但未被使用 [-Werror=unused-but-set-parameter]
../../binutils-2.20.1/bfd/compress.c:54:68: 错误: 形参‘size’被设定但未被使用 [-Werror=unused-but-set-parameter]
cc1: all warnings being treated as errors
make[4]: *** [compress.lo] 错误 1
make[4]:正在离开目录 `/home/rtems/tools/build-binutils/bfd'
make[3]: *** [all-recursive] 错误 1
make[3]:正在离开目录 `/home/rtems/tools/build-binutils/bfd'
make[2]: *** [all] 错误 2
make[2]:正在离开目录 `/home/rtems/tools/build-binutils/bfd'
make[1]: *** [all-bfd] 错误 2
make[1]:正在离开目录 `/home/rtems/tools/build-binutils'

make: *** [all] 错误 2

5.将工具链目录添加到系统环境变量,打开/etc/bash.bashrc(之前版本的ubuntu是bashrc文件),在文件末尾加入以下内容:

export PATH=/opt/rtems-4.10/bin:${PATH}

然后使修改生效:source /etc/bash.bashrc

6.安装gcc:

由于gcc的安装依赖gmp和mpfr,gmp又依赖m4,因此首先安装m4、gmp和mpfr:

安装m4:

apt-get install m4

安装gmp:

cd ../

mkdir build-gmp

cd build-gmp

../gmp-4.2/configure --prefix=/usr/local/gmp(该部分为安装目录)

make

make check

make install

安装mpfr:

cd ../

mkdir build-mpfr

cd build-mpfr

../mpfr-2.4.2/configure --prefix=/usr/local/mpfr --with-gmp=/usr/local/gmp(指定gmp的安装位置)

make

make check

make install

安装gcc:

cd ../

cd gcc-core-4.4.7/

ln -s ../newlib-1.18.0/newlib

cd ../

mkdir build-gcc

cd build-gcc

在/root/.profile中加入以下内容:

export LD_LIBRARY_PATH=/usr/local/mpfr/lib:/usr/local/gmp/lib:${LD_LIBRARY_PATH}

然后使修改生效:source /root/.profile

../gcc-4.4.7/configure --target=i386-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

make all(编译时间比较长,请耐心等待)

make info

make install

7.编译rtems源码包:

从官网下载rtems-4.10源码包;

然后:

tar jxvf rtems-4.10.2.tar.bz2

mkdir build-rtems

cd build-rtems

../rtems-4.10.2/configure --target=i386-rtems4.10 --enable-posix --enable-networking --enable-cxx --enable-rtemsbsp=pc386 --prefix=/opt/rtems-4.10/

make all install

一旦编译rtems没有出现错误,则说明工具链安装成功!
