1、安装一些必要的依赖库
apt-get install build-essential git-core checkinstall yasm texi2html libvorbis-dev libx11-dev libvpx-dev libxfixes-dev zlib1g-dev
apt-get install pkg-config netcat libncurses5-dev
apt-get install nasm libx264-dev
apt-get install libv4l-dev
apt-get install libasound2-dev
apt-get install libsdl2-dev
apt-get install libxext-devhtml
2、交叉编译asoundlinux
先下载alsa-lib-1.2.1.2.tar.bz2解压缩。c++
而后./configure CC=arm-linux-gnueabihf-gcc --host=arm-linux-gnueabihf git
makeweb
make installide
3、编译pjsip函数
./configure CC=arm-linux-gnueabihf-gcc --host=arm-linux-gnueabihf --disable-libwebrtc --disable-ssl --disable-openh264 --disable-libyuv --enable-static --prefix=/system/binoop
makeui
make installes5
4、使用pjsip静态库编译一个demo
makefile以下
OBJ= main CC= arm-linux-gnueabihf-gcc CFLAGS= -Wall -O -O2 -DPJ_IS_BIG_ENDIAN=0 -DPJ_IS_LITTLE_ENDIAN=1 VPATH= ./ #LIBS= -lpthread -lm INCLUDE= -I$(VPATH)include LIB_DIR= -L$(VPATH)lib LIB= -lpjsua2-arm-unknown-linux-gnueabihf -lstdc++ -lpjsua-arm-unknown-linux-gnueabihf -lpjsip-ua-arm-unknown-linux-gnueabihf -lpjsip-simple-arm-unknown-linux-gnueabihf -lpjsip-arm-unknown-linux-gnueabihf -lpjmedia-codec-arm-unknown-linux-gnueabihf -lpjmedia-arm-unknown-linux-gnueabihf -lpjmedia-videodev-arm-unknown-linux-gnueabihf -lpjmedia-audiodev-arm-unknown-linux-gnueabihf -lpjmedia-arm-unknown-linux-gnueabihf -lpjnath-arm-unknown-linux-gnueabihf -lpjlib-util-arm-unknown-linux-gnueabihf -lsrtp-arm-unknown-linux-gnueabihf -lresample-arm-unknown-linux-gnueabihf -lgsmcodec-arm-unknown-linux-gnueabihf -lspeex-arm-unknown-linux-gnueabihf -lilbccodec-arm-unknown-linux-gnueabihf -lg7221codec-arm-unknown-linux-gnueabihf -lpj-arm-unknown-linux-gnueabihf -lrt -lpthread -lasound -ldl -lm $(OBJ): $(CC) -o main.o main.c -Wall $(INCLUDE) $(LIB_DIR) $(LIB) -static clean: rm -f main
