PJSIP交叉编译

 

 

一、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-dev

二、交叉编译asound

       先下载alsa-lib-1.2.1.2.tar.bz2解压缩。

      然后./configure CC=arm-linux-gnueabihf-gcc --host=arm-linux-gnueabihf 

              make

              make install

三、编译pjsip

        ./configure CC=arm-linux-gnueabihf-gcc --host=arm-linux-gnueabihf  --disable-libwebrtc --disable-ssl --disable-openh264 --disable-libyuv --enable-static --prefix=/system/bin

        make

       make install

 

四、使用pjsip静态库编译一个demo

       makefile如下

        

OBJ= main

CFLAGS= -Wall -O -O2 -DPJ_IS_BIG_ENDIAN=0 -DPJ_IS_LITTLE_ENDIAN=1

$(OBJ):
    $(CC) -o main.o main.c -Wall $(INCLUDE) $(LIB_DIR) $(LIB) -static 

clean:
    rm -f main
