从源码编译安装msp430-gcc 4.7.2

背景

遇到的问题

最近在做关于Contiki操作系统在TelosB节点上的一些实验，但是在编译一些Contiki样例的时候遇到了".text"和".rodata"段出现重合无法成功编译的情况，查阅资料显示需要更新Instant Contiki中自带的msp430-gcc来解决这个问题。

本文将我的操作过程做一个记录，希望对读者有所帮助。

硬软件环境

Instant Contiki3.0（Ubuntu 14.04LTS）

1. 安装编译安装必需的应用

sudo apt-get install patch ncurses-dev build-essential bison flex libgmp3-dev libmpfr-dev libmpc-dev texinfo zlib1g-dev

外网上也有不少关于重新编译msp430-gcc的教程，但是他们的要求都是TEXINFO版本<5，但是上一步直接安装的texinfo的版本>5，需要卸载后从源码安装其4.xx版本：

TEXINFO

Remove Latest TEXINFO package using Synaptics.

ubuntu应该直接用apt卸载即可

从源码安装TEXINFO-4.13

wget http://ftp.gnu.org/gnu/texinfo/texinfo-4.13.tar.gz

解压源码:

gzip -dc < texinfo-4.13.tar.gz | tar -xf -

cd texinfo-4.13

Configure, build and install:

./configure

make

sudo make install

删除旧版msp430-gcc

仍然是使用apt卸载，不再赘述

编译安装新版msp430-gcc

准备工作

INSTALL_PREFIX="${HOME}/mspgcc-4.7.2"

echo The installatoin prefix:$INSTALL_PREFIX

创建放置源码的文件夹

# Switch to the tmp directory

mkdir tmp 

cd tmp

# Unpacking the tars 

tar xvfj binutils-2.22.tar.bz2

将msp430相关的patch合并到binutils和gcc中，编译并安装

# 1) Incorporating the changes contained in the patch delievered in mspgcc-20120911

cd binutils-2.22

patch -p1<../mspgcc-20120911/msp430-binutils-2.22-20120911.patch

cd ..

# 2) Incorporating the changes contained in the patch delievered in mspgcc-20120911

cd gcc-4.7.2

patch --force -p1<../mspgcc-20120911/msp430-gcc-4.7.0-20120911.patch

patch --force -p1<../0001-SF-352-Bad-code-generated-pushing-a20-from-stack.patch

patch --force -p1<../0001-SF-357-Shift-operations-may-produce-incorrect-result.patch

cd ..

# 3) Creating new directories

mkdir binutils-2.22-msp430

mkdir gcc-4.7.2-msp430

安装patch过的binutil

# 4) installing binutils in INSTALL_PREFIX

cd binutils-2.22-msp430/

../binutils-2.22/configure --target=msp430 --program-prefix="msp430-" --prefix=$INSTALL_PREFIX

make

make install

安装patch过的gcc

# 5) Download the prerequisites

cd ../gcc-4.7.2

./contrib/download_prerequisites

# 6) compiling gcc-4.7.0 in INSTALL_PREFIX

cd ../gcc-4.7.2-msp430

../gcc-4.7.2/configure --target=msp430 --enable-languages=c --program-prefix="msp430-" --prefix=$INSTALL_PREFIX

make

make install

编译和安装msp430所需的硬件描述文件与库文件

# 7) compiping msp430mcu in INSTALL_PREFIX

cd ../msp430mcu-20120716

MSP430MCU_ROOT=`pwd` ./scripts/install.sh ${INSTALL_PREFIX}/

# 8) compiling the msp430 lib in INSTALL_PREFIX

cd ../msp430-libc-20120716

cd src

PATH=${INSTALL_PREFIX}/bin:$PATH

make

make PREFIX=$INSTALL_PREFIX install

检查是否安装完毕

使用命令查看msp430-gcc的版本，如果是4.7.2则完成

msp430-gcc --version
