永远也记不住的linux环境变量，库文件，头文件，交叉编译...

一、环境变量
1、node-v4.9.1-linux-armv7l
1）安装
cp node-v4.9.1-linux-armv7l.tar.gz /usr/local/
cd /usr/local/
tar xvf node-v4.9.1-linux-armv7l.tar.gz

2）添加环境变量
export PATH=$PATH:/usr/local/node-v4.9.1-linux-armv7l/bin
export LD_LIBRARY_PATH=/usr/local/node-v4.9.1-linux-armv7l/lib:$LD_LIBRARY_PATH
添加到/etc/profile文件或者~/.bashrc文件
vi /etc/profie
export PATH=$PATH:/usr/local/node-v4.9.1-linux-armv7l/bin
export LD_LIBRARY_PATH=/usr/local/node-v4.9.1-linux-armv7l/lib:$LD_LIBRARY_PATH
source /etc/profile
vi ~/.bashrc
export PATH=$PATH:/usr/local/node-v4.9.1-linux-armv7l/bin
source ~/.bashrc
或者直接echo "export PATH=$PATH:/usr/local/node-v4.9.1-linux-armv7l/bin " >> ~/.bashrc

二、交叉编译，库文件，头文件
1、redis服务端
1）redis编译
wget http://download.redis.io/releases/redis-4.0.11.tar.gz
tar xvf redis-4.0.11.tar.gz
cd redis-4.0.11
#make MALLOC=libc
make MALLOC=Jemalloc
make install PREFIX=/usr/local/redis
sudo mkdir -p /usr/local/redis/etc
sudo cp redis.conf /usr/local/redis/etc
vi /etc/profile
export PATH=$PATH:/usr/local/redis/bin
source /etc/profile
/usr/local/redis/redis-server /usr/local/redis/etc/redis.conf

2）redis交叉编译
tar xvf redis-4.0.11.tar.gz
cd redis-4.0.11
export CC=arm-linux-gnueabihf-gcc
export CXX=arm-linux-gnueabihf-g++
export LD=arm-linux-gnueabihf-ld
export RAINLIB=arm-linux-gnueabihf-rainlib
export AR=arm-linux-gnueabihf-ar
export LINK=arm-linux-gnueabihf-g++
#make MALLOC=libc
make MALLOC=Jemalloc
make install PREFIX=_install
mkdir _install/etc
sudo cp redis.conf _install/etc
vi /etc/profile
export PATH=$PATH:/usr/local/xxx/bin
source /etc/profile
./redis-server /usr/local/xxx/redis/etc/redis.conf

2、redis c语言客户端
1）hiredis编译
make
make install PREFIX=_install
gcc -o example example.c -I ./_install/include/hiredis -L ./_install/lib -lhiredis
export LD_LIBRARY_PATH=/usr/local/hiredis/lib:$LD_LIBRARY_PATH
./example

2）hiredis交叉编译
export CC=arm-linux-gnueabihf-gcc
export CXX=arm-linux-gnueabihf-g++
export LD=arm-linux-gnueabihf-ld
export RAINLIB=arm-linux-gnueabihf-rainlib
export AR=arm-linux-gnueabihf-ar
export LINK=arm-linux-gnueabihf-g++
make
make install PREFIX=_install
arm-linux-gnueabihf-gcc -o example example.c -I ./_install/include/hiredis -L ./_install/lib -lhiredis
export LD_LIBRARY_PATH=/usr/local/hiredis/lib:$LD_LIBRARY_PATH
./example

3、pjsip移植

1）alsa交叉编译

export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabihf
tar xjvf alsa-lib-1.1.7.tar.bz2
cd alsa-lib-1.1.7/
./configure --host=arm-linux-gnueabihf CC=arm-linux-gnueabihf-gcc --prefix=/home/dong/alsa-lib-1.1.7/_install
make
make install

2）pjsip交叉编译

./configure --prefix=/home/dong/pjproject-2.8/_install --host=arm-linux-gnueabihf CC=/usr/local/gcc-linaro-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc --disable-libwebrtc CFLAGS=-I/home/dong/alsa-lib-1.1.7/_install/include LDFLAGS=-L/home/dong/alsa-lib-1.1.7/_install/lib

make dep

make

make install
