1.1 安装交叉编译环境
sudo apt-get update sudo apt-get install libtool shtool autoconf git-core pkg-config make gcc build-essential libgmp3-dev libmpfr-dev libx11- libx11-dev texinfo flex bison libncurses5 libncurses5-dbg libusb-0.1- libpcsclite1 libccid pcscd libncurses5-dev libncursesw5 libncursesw5-dbg libncursesw5-dev zlibc zlib1g-dev libmpfr4 libmpc-dev libpcsclite-dev
sudo ldconfig mkdir osm
cd osm
mkdir build install src
wget http://bb.osmocom.org/trac/raw-attachment/wiki/GnuArmToolchain/gnu-arm-build.3.sh
cd src
wget http://ftp.gnu.org/gnu/gcc/gcc-4.8.2/gcc-4.8.2.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 cd ..
chmod +x gnu-arm-build..sh
sudo bash gnu-arm-build..sh
1.2 设置交叉编译环境变量
cd install/bin
pwd vi ~/./.bashrc
export PATH=$PATH:/home/$username(change this to your name)/osm/install/bin #save and quit
source ~/.bashrc
0x02 源码编译CalypsoBTS
2.1 编译libosmo-dsp
git clone git://git.osmocom.org/libosmo-dsp.git
cd libosmo-dsp/
autoreconf -i
./configure
make
sudo make install
cd ..
2.2 编译osmocom-bb
git clone git://git.osmocom.org/osmocom-bb.git trx
cd trx/
git checkout jolly/testing
cd src/ # 需要 TX 功能支持
# 取消target/firmware/Makefile代码中'CFLAGS += -DCONFIG_TX_ENABLE' 前边的注释
# 并在make时启用transceiver功能支持
make HOST_layer23_CONFARGS=--enable-transceiver
2.3 安装依赖包
sudo apt-get install sqlite3 libdbi-dev libdbd-sqlite3 libsctp-dev
2.4 编译 Ortp
wget http://download.savannah.gnu.org/releases/linphone/ortp/sources/ortp-0.22.0.tar.gz
tar -xvf ortp-0.22..tar.gz
cd ortp-0.22./
./configure
make
sudo make install
sudo ldconfig
cd ..
2.5 编译libosmo-abis
git clone git://git.osmocom.org/libosmo-abis.git
cd libosmo-abis
autoreconf -i
./configure
make
sudo make install
sudo ldconfig
cd ..
2.6 编译libosmo-netif
git clone git://git.osmocom.org/libosmo-netif.git
cd libosmo-netif/
autoreconf -i
./configure
make

2.7 编译openbsc
编译Openbsc时需用到PCAP库文件，编译前先搜索&安装依赖包：
apt-cache search PCAP
sudo pat-get install libpcap-dev libpcap0. libpcap0.-dbg libpcap0.-dev
sudo ldconfig git clone git://git.osmocom.org/openbsc.git
cd openbsc/openbsc/
autoreconf -i
./configure
make
sudo make install
cd ../..
git clone git://git.osmocom.org/openbsc.git
cd openbsc/openbsc/
autoreconf -i
./configure
make
sudo make install
cd ../..
2.8 编译osmo-bts
git clone git://git.osmocom.org/osmo-bts.git
cd osmo-bts
autoreconf -i
./configure --enable-trx
make
sudo make install
cd ..
2.9 创建OpenBSC配置文件
#如果配置文件不存在需要先创建 Create the configuration folder if it isn't exist yet
mkdir ~/.osmocom
cd ~/.osmocom
touch ~/.osmocom/open-bsc.cfg
touch ~/.osmocom/osmo-bts.cfg

0x04 配置OpenBSC
4.1 启动BTS
终端1：
osmo-nitb -c ~/.osmocom/open-bsc.cfg -l ~/.osmocom/hlr.sqlite3 -P -C --debug=DRLL:DCC:DMM:DRR:DRSL:DNM
终端2：
telnet localhost

PC
IP：192.168.31.147 (通过WiFi连接)
路由器
IP:192.168.31.1
3G Access Point
IP:未知
方法1：进入路由后台，查找3G Access Point IP
方法2：通过abissip-find找到3G Access Point IP
cd openbsc/openbsc/src/ipaccess
#or
cd openbsc/openbsc/build-2G/src/ipaccess sudo ./abisip-find
4.3 Telnet连入3G Access Point
telnet 3G Access Point's IP 8090
