[size=x-large][b]简介[/b][/size]
osmocom是GSM协议栈(Protocols stack)的开源实现,全称是Open source mobile communication Baseband。目的是要实现手机端从物理层(layer1)到layer3的三层实现。

[size=x-large][b]环境[/b][/size]
基本kali linux,安装过程见上篇

[size=x-large][b]安装依赖[/b][/size]

sudo apt-get install libtool shtool autoconf git-core pkg-config make gcc build-essential libgmp3-dev libmpfr-dev libx11-6 libx11-dev texinfo flex bison libncurses5 libncurses5-dbg libncurses5-dev libncursesw5 libncursesw5-dbg libncursesw5-dev zlibc zlib1g-dev libmpfr4 libmpc-dev


[size=x-large][b]安装交叉编译环境[/b][/size]
参考:http://bb.osmocom.org/trac/wiki/GnuArmToolchain

[*]交叉编译环境的依赖

sudo apt-get install build-essential libgmp3-dev libmpfr-dev libx11-6 libx11-dev texinfo flex bison libncurses5 libncurses5-dbg libncurses5-dev libncursesw5 libncursesw5-dbg libncursesw5-dev zlibc zlib1g-dev libmpfr4 libmpc-dev


[*]创建文件夹

mkdir ~/lib/gnuarm
cd ~/lib/gnuarm
mkdir build install src


[*]下载build脚本

wget http://bb.osmocom.org/trac/raw-attachment/wiki/GnuArmToolchain/gnu-arm-build.2.sh
chmod +x gnu-arm-build.2.sh


[*]下载相关源代码

cd src/
wget http://ftp.gnu.org/gnu/gcc/gcc-4.5.2/gcc-4.5.2.tar.bz2
wget http://ftp.gnu.org/gnu/binutils/binutils-2.21.1a.tar.bz2
wget ftp://sources.redhat.com/pub/newlib/newlib-1.19.0.tar.gz


[*]开始build
这一步非常耗时,一边去看个电影吧

cd ..
./gnu-arm-build.2.sh


[*]设置环境变量
~/.bashrc 添加一行

$vi ~/.bashrc
# 添加下面这一行,记得替换用户名
export PATH=$PATH:/home/${username}/lib/gnuarm/install/bin

$source ~/.bashrc


没有设置此环境变量的情况下,编译osmocombb的时候会遇到以下错误

src/target/firmware/include/asm/swab.h:32: Error: no such instruction: `eor %edx,%ecx,%ecx,ror'

[size=x-large][b]安装osmocombb、libosmocore[/b][/size]
[*]下载源码

cd ~
git clone git://git.osmocom.org/osmocom-bb.git
git clone git://git.osmocom.org/libosmocore.git


[*]编译 libosmocore

cd ~/libosmocore
autoreconf -i
./configure
make
sudo make install
sudo /sbin/ldconfig


[*]编译osmocombb

cd ~/osmocom-bb
git checkout --track origin/luca/gsmmap
cd src
make

第一次编译的时候遇到以下错误,原因是最初没有设置gcc交叉编译环境,后来设置交叉编译环境的时候移动了gnuarm的位置,导致的错误,严格按照以上步骤执行即可。

报错:没有规则可以创建“apps/hello_world/main.o”需要的目标“/home/${username}/gnuarm/bin/../lib/gcc/arm-elf/3.4.3/../../../../arm-elf/sys-include/sys/types.h” 停止。

finally, done~
